What's New in Global Mapper v17.1

SDK-Specific Changes

Added support for loading generic ASCII text files with a coordinate order other than X-first or Y-first with GM_LoadGenericAsciiTextLayer. The old GM_AsciiFormatInfo_t.mYCoordFirst member is now named mCoordOrder and uses a new enumeration (GM_AsciiCoordOrder_t8). This change is binary compatible with old versions, but will require a code change if you are using that member. [Item #16864]
Added support for limiting which layers are listed in the online source dialog. New INC_LAYER and EXC_LAYER values are recognized in the extra flags parameter for GM_LoadOnlineLayer to allow providing include/exclude lists for filtering what is shown. [Item #17495]

Users can right-click with the Path Profile Tool active to switch to perpendicular profile mode and set the length of the perpendicular profiles.
New Custom Feature Extraction Tool for extracting 3D area and line features by graphically selecting the associated location for each feature on the perpendicular profile display. This provides a very easy way to digitize highly accurate 3D features from Lidar or terrain data, such as road edge and curb lines, powerlines, and buildings.
Added support for adding the path profile display to the multi-view layout. Users can now choose to add a new view of type Profile and the Path Profile Tool will use that for displaying the active path profile. Users can also add any path profile dialog to the multi-view interface via a new button or pop a multi-view profile view to its own dialog through a right-click option.
Added support for loading and saving the multi-view layout. By default the multi-view layout is now saved to and restored from workspace (GMW) files.

Added support for editing which classification groups a Lidar class belongs to. Right-click on a class on the Lidar filter configuration dialog and choose to Set Class Group(s) to choose if a class is a surface point (i.e. ground, water, road), vegetation, structure, etc. This makes it easier to use a classification system that differs from the standard ASPRS classifications. [Item #16561]
Fixed issue with the height above ground for some non-ground points being marked as 0 rather than the actual height above ground. [Item #15370]
Fixed issue with per-vertex elevation values for extracted building and tree features being interpreted as feet rather than meters when the Elevation Display/Export Units setting set to Statute. [Item #16593]
Fixed color “fuzziness” selector on Lidar filter dialog. The selected value was previously ignored and a value of 16 always used. [Item #16661]
Fixed issue with elevation modifications from Alter Elevation Values tab of Options dialog for Lidar point cloud layers (i.e. scale, offset, etc.) not saving to workspace files. [Item #16872]

LiDAR Changes

New Custom Feature Extraction Tool for extracting 3D area and line features by graphically selecting the associated location for each feature on the perpendicular profile display. This provides a very easy way to digitize highly accurate 3D features from Lidar or terrain data, such as road edge and curb lines, powerlines, and buildings.
[LIDAR MODULE ONLY] Added button to Lidar toolbar to allow quickly marking points as a ground point (class 2). [Item #16524]
[LIDAR MODULE ONLY] Added support for editing which classification groups a Lidar class belongs to. Right-click on a class on the Lidar filter configuration dialog and choose to Set Class Group(s) to choose if a class is a surface point (i.e. ground, water, road), vegetation, structure, etc. This makes it easier to use a classification system that differs from the standard ASPRS classifications. [Item #16561]
Made Lidar point clouds render before line features by default so that line features are more visible on top of dense Lidar point clouds even when zoomed out. [Item #16716]
Improved load of Lidar point clouds from generic ASCII text files. Additional column layouts are recognized, including XYZI, XYZRGB, and XYZIRGB. In addition, if the file has named columns, any column layout works as long as it has recognized column names, like RED, GREEN, BLUE, INTENSITY, NIR, etc. [Item #16811]
When selecting with a left click in the Feature Info and Digitizer Tools, make normal line and point features be of higher precedence than Lidar point cloud points, making it easy to select normal features that are drawn with Lidar data. [Item #16716]
Made Lidar Model Key Points be treated as surface/ground points so they can be used for calculating height-above-ground. [Item #15370]
Reduced load time for Lidar point clouds, GMP files in particular. [Item #16313]
Added display of 24-bit RGB color as RGB attribute in Feature Info dialog for Lidar points in clouds with 16-bit per band colors to make it easier to filter based on color. [Item #16641]
When loading LAS/LAZ files that have points outside the bounding box specified in the header, give the user the option to keep or toss these points for all files in the current load operation rather than prompting for each one. [Item #16813]
[LIDAR MODULE ONLY] Fixed issue with the height above ground for some non-ground points being marked as 0 rather than the actual height above ground. [Item #15370]
[LIDAR MODULE ONLY] Fixed issue with per-vertex elevation values for extracted building and tree features being interpreted as feet rather than meters when the Elevation Display/Export Units setting set to Statute. [Item #16593]
[LIDAR MODULE ONLY] Fixed color “fuzziness” selector on Lidar filter dialog. The selected value was previously ignored and a value of 16 always used. [Item #16661]
[LIDAR MODULE ONLY] Fixed issue with elevation modifications from Alter Elevation Values tab of Options dialog for Lidar point cloud layers (i.e. scale, offset, etc.) not saving to workspace files. [Item #16872]

3D Viewer Changes

Selections for Lidar points are now rendered as cubes rather than squares. [Item #16618]
When adding models in the Configure Features dialog, the units chosen by the user are now used to scale the models in the 3D viewer. Any units/scaling information in the model itself is ignored. [Item #16455]
Fixed 3D display of Lidar point clouds when loaded with raster layers or from a map catalog when no gridded terrain data is loaded. The flat raster surface now draws at the height of the lowest Lidar point rather than at a height of 0. [Item #16644]
Made Flythrough Path Edit dialog resizable. [Item #16772]
Fixed display of model points added by creating a new feature type with a 3D model on the Edit Feature dialog. [Item #16625]

Fixed handling of 3D point features that have height values that are interpreted as “Above elevation” in the Feature Types/Labels/Elevations tab of the Vector Options dialog. [Item #17005]
Fixed scaling of 3D point models that have height of 0, and use a symbol scale that is a fixed distance in ground units. [Item #17090]
Path profiles are now automatically added to the 3D view, and tracking of the profile in a path profile view is now reflected in the 3D view, similar to how its done in a 2D view. [Item #17022]
Fixed issue with 3D view dialog not remembering its size and position. [Item #17354]

Path Profile/Line of Sight Function Changes

Added support for extracting/digitizing 3D area and line features along linear paths using the path profile tool while displaying perpendicular profiles along the source path. This powerful new feature includes the following capabilities: [Item #15950]

Improved responsiveness of path profile dialog when dragging a path. [Item #16669]
Fixed error in v17.0.0-v17.0.1 when a path profile is being displayed and user unloads all data or change the view projection. [Item #16520]

Analysis Function Changes

Updated reported results for volume between surfaces to include information about the layers being compared, the time the analysis was performed, and the area features the volume was calculated within (if applicable). [Item #15803]
Updated reported cut-and-fill volume results so that the net volume (cut minus fill) is now reported as a NET_VOLUME value and the TOTAL_VOLUME is the sum of the cut and fill volumes. [Item #15812]
Added support for TRANSMITTER_HEIGHT_MS and RECEIVER_HEIGHT_MS as recognized attributes when creating view sheds from selected point features. They contain the transmitter and receiver heights relative to sea level (as compared to relative to ground for the non-MS versions). They respectively are the same as the OFFSETA_MS and OFFSETB_MS attributes. [Item #16710]
Added option to copy the results of measurement (including volume) of one or more features to the clipboard as text, either from the Analysis menu or Digitizer Tool right-click menu. [Item #17044]
Added new functions to the raster calculator: the trigonometric functions sin, cos, tan (sine, cosine and tangent, angle specified in radians), asin, acos, atan (arcsine, arccosine and arctangent, result specified in degrees), sin_deg, cos_deg, tan_deg (sine, cosine and tangent, angle specified in degrees), and sqrt (square root). [Item #17184]
Updated Layer Statistics dialog to include ‘Check All’ button for quickly selecting all attributes as well as be resizable. [Item #17364]

Digitizer Tool Changes

Improved display of selected area features using a solid fill style. Now rather than being completely transparent with a cross-hatch, they will be filled with a partially transparent background the same color as the fill style of the area. The same applies for the Feature Info Tool. Those selected areas will be filled with a partially transparent background as well. [Item #17230]
Updated calculation of chainage (connecting selected points to nearest selected line) to include the name and layer of the connected point and line in the attribute list for the chainage line. Also renamed the right-click menu entry for this option to add CHAINAGE at the start to make it easier to find. [Item #15867]
Added option when copying attributes from point features to area features they are included in to create cloned copies of the area features for each point if there are multiple points within an area. [Item #15774]
Fixed placement of point features created at centroid of selected area features. Some centroids were not exactly where they needed to be. [Item #16337]
Fixed issue with selection of vertices only in selected areas by holding down S when dragging a selection box. This operation was correctly updating the selection, but was not automatically redrawing so users couldnt see the results until user forced a redraw. [Item #17036]

Scripting Changes

Added support for exporting ADRG or ASRP format files using the EXPORT_RASTER script command. [Item #17109]
Added EXPORT_PDF3D command to export to 3D PDF file from a script. [Item #17116]

Added support for specifying the COVERAGE_SMOOTHING_FACTOR when using the GENERATE_LAYER_BOUNDS command to create polygonal coverages rather than prompting the user for the smoothing to use. [Item #16586]
Added new parameter, USE_EXACT_BOUNDS, to be used when defining the bounds in a script command so that the command uses the specified bounds instead of the intersection between the specified bounds and the full data bounds. [Item #16827]
Added progress reporting when exporting multiple tiles from a single EXPORT_ELEVATION/EXPORT_RASTER/EXPORT_VECTOR script command. [Item #17031]
Added option to DEFINE_SHADER script command to control whether or not the shader is saved between runs to the custom_shaders.txt file. Enabled by default, add SAVE_SHADER=NO to cause defined shader to NOT be saved between runs. [Item #17150]
Allow loading workspace (.gmw) or script (.gms) files using the IMPORT script command. Just provide a workspace or script in the FILENAME parameter and it will now act like EMBED_SCRIPT was used. [Item #17188]
Fixed bug with specified SAMPLING_METHOD not being obeyed when exporting from the EXPORT_RASTER or EXPORT_ELEVATION script command. [Item #16903]
Fixed bug causing extra pixel to be added to right and bottom of EXPORT_RASTER results in some cases. [Item #16997]
Fixed crash using LAYER_LOOP_START…LAYER_LOOP_END with a script command that unloads some layers that were loaded when the loop started, like SPLIT_LAYER. [Item #17168]

Online Source Changes

Fixed issue with slow display of some tiled online sources. [Item #16575]
Fixed issue with exporting high resolution terrain to OSM web tiles for display as a streaming source. Now the full elevation units will be maintained for all zoom levels that can handle that much detail and not just the most detailed layer. The default elevation units selection is now also much better based on the loaded data. [Item #16575]
Fixed issue with initial display of elevation legend range when loading streaming online sources. [Item #16659]

Projection/Datum Changes

Changed priority to prefer projections from .aux.xml and .prj files when loading raster/image files that have known position information but not known projections (i.e. ECW). [Item #16768]
Added support for ground-to-grid scale factor in load-time coordinate transformations via a .gm_xform file in the same folder as the projected vector file being loaded. [Item #17001]
Fixed reprojected display of some images when converting between orthogonal projections (i.e. Mercator and Geographic). At some zoom levels the display would look striped. [Item #16869]
Fixed issues using a custom datum based on a control point file when transforming coordinates outside the control point convex hull. [Item #16976]
Fixed displayed lat/lon locations on the status bar when the option is checked to always display using WGS84. [Item #17207]

Format Specific Changes

Allow high bit depth JPEG2000 files to be exported from the 64-bit version of Global Mapper. [Item #16528]
Significantly sped up display of NITF images with embedded JPEG2000 data, especially when zoomed out. [Item #16838]
Added code page (language) support to GMP files. Any exported GMP files retain the code page of the layers being exported. If the GMP files includes multiple layers with varying code pages in a single GMP layer, all text is converted to UTF-8 so all text can be properly maintained. [Item #16744]
Added option to generate PRJ (projection) files when exporting BIL/BIP/BSQ files. [Item #16727]
Updated import of 3D model formats to show the import options dialog at least once for each group of 3D models loaded. The Use for All button on that dialog now applies just to the current load operation, so the options dialog is no longer gone forever. [Item #16740]
No longer show prompt to confirm load of file when a layer based on the same filename is already loaded for file types that provide a list of layers to the user to select from, like HDF5 or NetCDF format files. [Item #16742]
Improved export to multi-band image files with 32-bit float samples to support filling gaps by interpolating nearby values. [Item #16760]
Updated the load of NITF images with RPC geolocation information. Now if both RPC and corner positions are known, the user is prompted for which to use as RPC is not always the desired choice. If RPC is used, the coordinate conversions are now done at the elevation for each location rather than a height of 0. If terrain data is loaded that is used to get the elevation, otherwise the mid-point elevation for the entire file scene is used from the header. [Item #16782]
Updated Control Center right-click option to add selected layers to a new map catalog to allow adding to an existing map catalog file rather than always creating a new one. [Item #17153]
Added option to Advanced section of General tab of Configuration dialog to allow the use of an alternate PDF rendering engine when loading PDF files. This option can be useful if the default rendering engine is not providing the desired results. [Item #16859]
Made 3D text imported from DGN files keep the elevation. [Item #16987]
Updated GeoJSON export to keep per-vertex elevations. [Item #17051]

Updated MapInfo import to use font information for text point features so imported data looks more like it did when saved from MapInfo. [Item #17201]
Added support for additional projections when exporting to GeoTIFF. Now projections that cant be directly encoded will store their WKT projection string in the PCS citation key. For example this now allows storing Mollewide projections. [Item #17266]
Added support for reading and writing DPI values for PNG files. Now a PNG file with a DPI set will display that in the metadata. Exports to PNG via a script also now support the DPI parameter. [Item #17351]
Added ability for user to specify that a base be added to the generated STL mesh when exporting DEM. A new script option, “ADD_BASE” is also provided for the export script command. [Item #17340]

Updated default font character set to be based on the system locale (code page) set for non-Unicode applications. If set to Polish (for example), the default character set will be Eastern European. Users can change the setting from Default to a specific character set if users don’t want it based on the current system locale. [Item #16739]
Added built-in Band Setup presets for Worldview 2/3 DigitalGlobe images for easy selection of Natural Color and Color Infrared (CIR) bands from those 8-band products. [Item #16838]
Made point/text features with rotated text keep the text rotated the same angle relative to the map features when map view rotation is also used. [Item #16987]
Fixed issue with changes to the Band Setup not being correctly reflected in images using shared automatic contrast adjustment settings. [Item #16838]
Fixed issue with right-click options on elevation legend and scale bar to hide the [Items or change their styles not updating them until user zooms or pans the map. [Item #16633]
Fixed error rendering lines with some styles when they are small enough to be a single pixel on the screen. [Item #16639]
Fixed slope display and hill shading for layers using a distorted projection (i.e. Geographic, Mercator, etc.) covering a large area and using native elevation units other than meters. The calculated slope and applied shadow would be off by the elevation unit conversion factor to meters. [Item #16453]
Fixed issue with display of area features using some complex border styles (i.e. offset line styles). [Item #16852]
Allow map layout elements (scale bar, legend, grid lines) to be included when exporting selected layers from the Control Center to a raster image format (i.e. JPG, GeoTIFF, etc.). Before the export of selected layers would only include the layer even if user selected to include map layout [Items on the export options dialog. [Item #16541]
Improved image rectification and vector layer transformations based on control points in many cases where the results were not ideal. [Item #16976]
Made files loaded by dragging and dropping from Windows Explorer be added to the recently opened files list and used to update the Recently Used File Types filter. [Item #16815]

Added option to save selected result [Items to a CSV / Excel file on the Search dialog. [Item #17026]
When generating polygonal coverage areas from vector/Lidar layers from the Control Center only show a single dialog prompting the user for the smoothing factor to use rather than a separate dialog for each layer. [Item #16586]
Assign feature description from recognized attributes (i.e. LAYER, DESC, etc.) when loading vector formats. [Item #16530]
Updated export option to keep an input pixel if any part of the pixel is inside the export crop area to also work for non-polygonal crops. This means that if the option is checked in the Advanced section of the General tab of the Configuration dialog, any source pixels that at least partially overlap an output pixel bounds will be used and not just those that include the output pixel center. [Item #17193]
When cropping to area features for export or loading Lidar LAS/LAZ files and area features are selected both in the Feature Info Tool and Digitizer Tool, prefer the Digitizer Tool selection over the Feature Info selection. Previously the reverse order of preference was used, making it impossible to crop to a selected polygon while loading a Lidar file referenced in attributes of an area selected with the Feature Info Tool. [Item #17370]
Fixed issue with image rectification with 2 points using the automatic mode if the points result in negative X or Y scales. The rectifier was switching to Helmert in some situations that didnt provide good results. [Item #16502]
Fixed crash with large amounts of data loaded (several hundred layers) with some operations, like view shed. [Item #16713]
Fixed bug exporting to raster format (i.e. JPG, GeoTIFF, etc.) when all that is loaded is vector data in the User Created Features layer. No data was exported in that case. [Item #17006]
Fixed a bug in the Feature Types/Labels/Elevations tab on the Vector Options dialog: the height attribute value and height above/below elevation setting value were not handled correctly, so that the settings did not affect Global Mapper operations, particularly 3D display. [Item #17054]
Fixed a bug where the Export model as Y-up setting in the 3D File Export Options tab was ignored. [Item #17101]
Fixed join of attributes to a vector layer from a text file encoded using UTF-8 when non-ASCII characters are present. [Item #17220]

Misc. Changes

Added support for adding the path profile display to the multi-view layout. Users can now choose to add a new view of type Profile and the Path Profile Tool will use that for displaying the active path profile. Users can also add any path profile dialog to the multi-view interface via a new button or pop a multi-view profile view to its own dialog through a right-click option. [Item #16294]
Added support for loading and saving the multi-view layout. By default the multi-view layout is now saved to and restored from workspace (GMW) files. There is an option on the Map View Manager dialog to disable the save and restore of the multi-view layout. There are also Load and Save buttons on the Map View Manager dialog. [Item #16292]
Added support for filtering which layers are displayed in each 2D map view in the multi-view interface. Users can right-click on a 2D map view on the View Manager dialog and choose to select which layers are displayed in each view. [Item #17089]
Added support for splitting containers of multiple map views. This allows adding a new map view that crosses multiple existing maps, like have 2 side-by-side maps, then adding a new view (like a path profile) above or below those and spanning both maps. Previously users could only insert a new view by splitting an existing single map view. [Item #17281]

Added the ability to control whether toolbar/menu items for an extension are enabled/disabled and checked/unchecked using a new GM_Event_GetExtensionCommandState event. This event will be set whenever the state of the command item is needed. The extension simply needs to handle it in the HandleGMEvent function to set the state.
Added new options for the ‘keep GPS vessel on screen’ (GM_MiscOpt_GPSCenterOnVehicle) and ‘orient view to GPS vessel heading’ (GM_MiscOpt_GPSOrientTrackUp) options.

Significant New Features

Dramatically sped up nearly all Lidar operations, including load, display, gridding, and automatic classification.
Added support for automatically classifying powerline points from a Lidar point cloud. The new powerline classification options are available on the non-ground Lidar classification dialog and via the LIDAR_CLASSIFY script command.
Added support for automatically extracting powerline line features from a Lidar point cloud with Lidar points classified as a powerline type. The new powerline extraction options are available on the Lidar extraction dialog and via the LIDAR_EXTRACT script command.
Added support for automatically identifying high and low noise points from a Lidar point cloud. There is a new button on the Lidar toolbar providing this option as well as support in the LIDAR_CLASSIFY script command.
Added support for editing which classification groups a Lidar class belongs to. Right-click on a class on the Lidar filter configuration dialog and choose to ‘Set Class Group(s)’ to choose if a class is a surface point (i.e. ground, water, road), vegetation, structure, etc. This makes it easier to use a classification system that differs from the standard ASPRS classifications.
Added new Multi-View interface, allowing the embedding of multiple resizable 2D and 3D map views inside the main map view. The new Add/Remove Map Views toolbar and menu option allows adding any number of additional map views to the main map window. The maps fit together like a puzzle and can be dragged to resize within the main map view as desired. The views are independently zoomed and panned, allowing you to visualize your data in new and exciting ways!
Dramatically sped up nearly all Lidar operations, including load, display, gridding, and automatic classification.
Made Lidar Model Key Points be treated as surface/ground points so they can be used for calculating height-above-ground.
Support 3D Models as Custom Symbols for Point Types. The Configure Point Styles dialog allows the user to add 3D models to be used for rendering point features in the 3D viewer. Models can be attached to point styles or to individual features. Models can be sized automatically or by attribute.
Added several built-in online sources, including US National Map sources (w/ 1 foot color imagery source), World Navigation Charts (1:1M Scale ONC Charts), and Australian water sources.
Fixed issue with the height above ground for some non-ground points being marked as 0 rather than the actual height above ground.
Fixed issue with per-vertex elevation values for extracted building and tree features being interpreted as feet rather than meters when the Elevation Display/Export Units setting set to Statute.

[LIDAR MODULE ONLY] Fixed issue with extraction of separate roof pieces from classified Lidar point clouds. It would not work if the point cloud used linear units other than meters. [Item #16380]

3D Viewer Changes

Support 3D Models as Custom Symbols for Point Types. The Configure Point Styles dialog allows the user to add 3D models to be used for rendering point features in the 3D viewer. Models can be attached to point styles or to individual features. Models can be sized automatically or by attribute. [Item #14378]
Behavior of 3D Viewer Zoom and Arrow toolbar button change. The Zoom In and Zoom Out toolbar buttons in the 3D Viewer move behave the same as the mouse scrollwheel. The Left, Right, Up, and Down toolbar buttons now behave the same as their respective arrow keys on the keyboard. They no longer cause redraws in the 2D view, nor do they affect the bounds of the 3D view scene. [Item# 15805]
Allow cancelling a draw of 3D Lidar that is taking a while by pressing the Escape key, an arrow key, or clicking with the mouse. [Item #15811]
Made 3D progress bar display progress while rendering Lidar point data. [Item #15811]

Added ability to save fly-through frames as a series of BMP, JPG, or PNG files. [Item #15970]
Fixed issue where fly-through would not maintain height above terrain surface between key frames. Regenerate path data using “Relative” altitude mode to enable. [Item #15253]
Fixed issue where fly-through view would not be correct if path layer is not in global projection. [Item #16125]
Fixed issue where toolbar buttons would not show correct option enabled state when clicked during fly-through. [Item #16371]
Support 3D Models as Custom Symbols for Point Types. The Configure Point Styles dialog allows the user to add 3D models to be used for rendering point features in the 3D viewer. Models can be attached to point styles or to individual features. Models can be sized automatically or by attribute. [Item #14378]
Speed up performance of texture-based point symbols in the 3D viewer. For point features that use a standard bitmap-based rendering in the 2D viewer, panning and zooming is greatly enhanced in the 3D viewer. In general, texture handling for point symbols and meshes has been improved in the 3D viewer, and some standard symbols (e.g. the dot symbols) are now implemented using a non-texture based approach. [Item #16312]

Path Profile/Line of Sight Function Changes

[LIDAR MODULE ONLY] Allow undeleting deleted Lidar points on the Lidar path profile. If deleted features are displayed and some deleted Lidar points are selected, the user will be prompted whether to undelete the deleted points or to delete the selected normal points. [Item #16018]
Fixed display of path profile for a multi-point line when changing the sampling to only show the heights at vertices/endpoints. [Item #15817]

[LIDAR MODULE ONLY] Fixed issue with deleted Lidar points still being used for selection on the Lidar path profile when deleted features aren’t being displayed. [Item #16018]
Analysis Function Changes
When creating/modifying attributes via formula, either in the Attribute Calculation Setup dialog or by script, the formula is now persisted, along with the associated attribute, into the layer(s) being modified. The Attribute Calculation Setup dialog can now reference and display the previous formula for the new attribute, if one exists, so that a user can have an idea of what changes a previous formula made to an attribute. [Item #15322]
The Attribute Calculator and Raster Formula Calculator have new Excel-like AND() and OR() logical functions, which function similarly to equivalent infix operations. That is, the formula “AND( A, B, C )” is equivalent to the formula “A AND B AND C”; likewise for the new OR() function. [Item #15322]
Updated Watershed analysis tracing flow to or from selected area, line, or point features to include a TRACE_FLOW_DIR attribute in each generated area with the traced flow with a value of ‘FLOW_FROM’ or ‘FLOW_TO’ to indicate what direction the flow in the area is indicating. This can be useful for modifying styling based on the type of flow watershed. [Item #16289]

Digitizer Tool Changes

Added a new right-click option on the Feature Vertex dialog so you can easily duplicate vertices for an area feature. This allows you to use the “Pen Up” draw mode option to turn off the drawing of some segments of the area border. [Item #15997]
When creating a regular grid of features with the cell count or size calculated from a rectangle, make the rectangle bounds option of all loaded data actually use all loaded data and not the screen bounds. [Item #16108]

Support using parts of the filename for each grid cell in the parameters for an EXPORT command that grids the operation in to multiple pieces. You can use one of %TILE_DIR%, %TILE_FNAME_W_DIR%, %TILE_FNAME%, and %TILE_FNAME_WO_EXT% in the parameter list for the gridded command to have the corresponding part of the grid cell filename replaced in the parameter value. [Item #16247]
Support sending LOG_MESSAGE text to a different file than default script messages by using SET_LOG_FILE with a USER_FILENAME parameter specifying the file to send explicit LOG_MESSAGE text to. [Item #15940]
Fixed issue with LOG_MESSAGE command adding extra blank line. [Item #16259]
Updated LOG_MESSAGE command to support adding your own line breaks with \n and tabs with \t. [Item #16259]
Added SNAP_BOUNDS_TO_SPACING and SNAP_BOUNDS_TO_MULTIPLE parameters for EXPORT script commands to allow snapping the operation bounds either to the nearest sample spacing (for raster/elevation operations) as well as to the nearest multiple of a provided number. If SNAP_BOUNDS_TO_SPACING is not provided, the snapping for spacing will obey the option to snap export bounds to the nearest sample spacing bounds found in the Advanced section of the General tab of the Configuration dialog and set-able using the SET_OPT command with MISC_OPT=EXPORT_BOUNDS_SNAP_SPACING. [Item #16228]
Added pre-defined variables for using the script folder (%SCRIPT_FOLDER%) and Global Mapper version (%GM_MAJOR_VER%, %GM_FULL_VER_W_DATE%, %GM_FULL_VER_NO_DATE%) in a script. [Item #16285]
Added Global Mapper version (GM_VERSION) and saved time (TIMESTAMP) to the GLOBAL_MAPPER_SCRIPT command at the start of a saved workspace. [Item #15864]
Removed requirement that a VERSION parameter be included with the GLOBAL_MAPPER_SCRIPT command at the start of a script. If the parameter is there, it must have a value of 1.00. [Item #15864]
Allow providing number of sample points for CREATE_POINTS_ALONG_FEATURES, RESAMPLE_FEATURES, and CREATE_PERP_LINES_ALONG_FEATURES options for EDIT_VECTOR script command. Use a negative number for those values to specify a sample count rather than sample distance in meters. [Item #16059]
Allow selecting a file that doesn’t exist yet (i.e. filename to save) with the DEFINE_VAR script command with PROMPT=FILE. Just add FILE_MUST_EXIST=NO to the command to allow entering any filename. [item #15875]
Added support for specifying the attribute to use for the layer name in DWG/DXF exports using the LAYER_NAME parameter for the EXPORT_VECTOR script command. [Item #15935]

Allow variable replacement for lines in a DEFINE_PROJ section. [Item #16001]
Added support for extruding the edges of the generated mesh when exporting elevation data to STL format when using the EXPORT_ELEVATION command. Just add EXTRUDE_EDGES=YES to the command to enable extrusions, and optionally, add, for example, BASE_ELEVATION=50 to extrude to an elevation of 50 (the default is 0). When extrusion is enabled, any grid rectangle that has a corner that's invalid (i.e., is not present in the gridded data) or below the base elevation setting is excluded from the export. These options are also supported in the UI when exporting elevation data to STL. [Item #15914]
Added scripting control for exporting 3D models in “Z-up” and “Y-up” orientations. When using the EXPORT_ELEVATION command to export elevation data to STL format, which exports to Y-up orientation by default, add Z_UP=YES to export to Z-up orientation instead. Conversely, when using the EXPORT-VECTOR command to export vector features to 3D model formats like OBJ, STL, DAE, etc. (but not SketchUp), add Y_UP=YES to the command to cause it to export to Y-up orientation instead. In addition, you can add NO_PROMPTING=YES to the EXPORT_VECTOR command to prevent the 3D export options dialog from popping up during your script. [Item #16045]
Made EXPORT_ELEVATION and EXPORT_RASTER script commands obey the option to snap export bounds to the nearest sample spacing bounds. [Item #16228]
Fixed issue with SAVE_WORKSPACE command not writing out all of the needed DEFINE_PROJ commands for layers using user-specified projections. [Item #16347]

[Item #16048]
Make it easier to add ESRI RESTful services. The [Item to use was renamed from ‘Google Maps Tiles’ to ‘ESRI RESTful/Google Maps Tiles’ to make it more obvious. In addition, common URL mistakes are automatically detected, including missing slashes at the end or incorrect tile sizes. The server will be checked to see which of several options creates a working source rather than depending on the user to get everything correct to start with. [Item #15838]
Added built-in Korean VWorld DEM streaming terrain source with high resolution terrain for part of the world. This source requires an API key from the data provider. You can script these sources with the IMPORT_OSM_TILE command and SOURCE_TYPE=”VWORLD_DEM” provided. [Item #16103]
Fixed issue with newly added sources not showing up in the source list the next time you run Global Mapper due to an incorrect <MaxVersion> value being saved for the source in the user_online_sources.xml file. [Item #15836]
Fixed issue load data from some WFS sources (like FEMA Hazards) that expect the lat/lon bounding box in a different order than the standards would require. [Item #16004]
Fixed issue with default bounds for some WMS sources not being cropped to the max lat/lon bounds specified for the source. [Item #16184]
Fixed issue with custom TMS online sources with a custom tile URL not using the correct row numbering. [Item #16227]

Projection/Datum Changes

Improved projection names stored in PRJ files and GeoTIFF headers (PCSCitation and GTCitation). Now if you load a WKT PRJ file, the projection name will be remembered and used for export. If no name is known on export, a web service is queried to try and determine the projection name. A good default is used for common projections. There is also a new epsg_codes.txt file in the user settings folder that allows overriding EPSG code definitions and adding ‘name=’ parameters to the end to specify the friendly PROJCS name. [Item #13814]
Improved assignment of datums from WKT PRJ files when a TOWGS84 transformation is defined. If multiple datums match the name specified, the datum transformation closest to the specified TOWGS84 is used. [Item #16104]

Updated Hotine Oblique Mercator B projection to save name in WKT PRJ files as ‘Hotine_Oblique_Mercator_Azimuth_Center’ rather than just ‘Hotine_Oblique_Mercator’ which is also written out for the Hotine Oblique Mercator Azimuth Natural Origin projection. [Item #15888]
Made Hotine Oblique Mercator Two Point Natural Origin projections load from WKT PRJ files. [Item #16203]
Fixed initialization of lat/lon crop boundary on Cropping tab of Options dialog and actual crop to lat/lon bounds for UPS North/South and other projections that are highly non-orthogonal to the lat/lon grid. [Item #16017]

Format Specific Changes

[16.2.5] Fixed issue with metadata for layers in a map catalog just flashing for a second and going away if that layer wasn’t already displayed. [Item #16124]
Improved performance of OTF feature load. [Item #16140]
Made OTF import as map catalog optional to permit splitting of features into separate layers. [Item #16153]
Fixed issue where GeoCalc transform information was not saved for all layers in a workspace, requiring user to pick transforms again when loaded. [Item #14051]
Updated DXF and DWG export when exporting feature labels as attributes to place the attribute at the appropriate Z (elevation) rather than at 0.0. [Item #16161]
Fixed display of Tobin BAS files with border segments turned off. [Item #16168]

Added new GPS toolbar buttons to control whether or not the main display centers on the GPS vessel location and automatically rotates to keep the GPS heading towards the top of the display. [Item #16043]
Allow update of GPS location on display up to 10 times per second (vs. about 3 before). In addition, new GPS locations are drawn more immediately after they are received in most cases. This helps with high frequency GPS devices traveling at high speed, such as in an aircraft. [Item #15937]

Rendering/Style Changes

Made vertical lines and lines that are a single pixel at a zoom level draw as a single pixel on the screen rather than not drawing at all. [Item #16229]
Updated Feature Info Tool when selecting a sample/pixel from a loaded raster/elevation layer to display the full bounds of the sample when zoomed in and to also draw the circle at the center of the cell and not the clicked location. [Item #16426]
When not displaying all labels regardless of overlap and drawing each vector layer (and labels) separately based on the Vector Display Order During Draw setting, don’t draw labels further down in the layer list that would overlap an already drawn label. [Item #15913]
Allow symbol scale factor to work when applied to a custom shape symbol that is defined with a default size and color. [Item #16115]
Fixed issue with fixed screen position layers (including scale bar, legend, etc.) briefly jumping around when playing back video linked to a line feature. [Item #15897]
Fixed issue with partially see-through raster layers not updating automatically when the display of a terrain layer underneath changes. [Item #15792]

Fixed a problem where dragging a rotated map using the middle mouse button didn’t re-center correctly [Item #15974]

Misc. Changes

Updated display of coordinates on the status bar. UTM projections now include the zone number. If there is a terrain value available and the Z units are not the same as the XY units, the XY and Z units will be display separately to avoid confusion. [Item #15853]
Added ‘LOAD TIME’ to metadata for all layers showing how long it took to load the layer. [Item #15928]
Fixed loading of layers with a faked position to use arc seconds rather than arc degrees for the ground units so the data doesn’t cover a huge part of the earth or become invalid. [Item #16069]
Automatically use the Helmert transformation for layer rectification when provided just 2 control points that result in the X and Y pixels being significantly different in size and/or inverted when a simple Linear transformation is used. [Item #16035]
Made changing of user settings file path on Help->About dialog copy over all files from the old settings path. Previously some settings, like the user online sources, were not being copied when changing to a new settings path. In addition you are now prompted to delete all files that were successfully moved over so you don’t end up with the old copy sticking around. [Item #15934]
New Cartographic Map Publishing tool including:
- A paper scale interface that actually lets you see the layout in the paper proportions.
- Easier addition of overlays for graphics, text, legend, scale bar, north arrows, etc. and positioning these elements through click and drag
- Template creation and template library
Made resampling method box on many dialogs (watershed, water rise, raster/terrain export, etc.) reset X and Y sample spacing to defaults when changing from a box resampler to a normal one if the user hasn't changed the spacing manually. [Item #15972]
Fixed issue with attributes containing ‘ELE’ somewhere in the string being treated as elevation attributes when no other obvious elevation choices can be found. For example, a file with a ‘PipeLength’ attribute was treating that attribute as elevation automatically. [Item #15840]
Fixed rare crash doing multi-threaded operations that also does reprojection, like roughness grid area finding, equal-area creation from rasters. [Item #15815]
Fixed issue with file associations not being correctly set on install for Global Mapper formats (.gmg, .gmp, etc.). [Item #14513]
Fixed issue with yellow border around exported image formats when drawing a box to specify the export bounds and including map layout elements (scale, legend, etc.). [Item #16204]

What's New in Global Mapper v16.2

SDK-Specific Changes

Added new GM_SetProjectionEx function to allow easily selecting the best zoned projection (like UTM) for a lat/lon bounding box. You just provide the basic zoned projection setup (i.e. projection system, datum, and units) and the lat/lon bounds and the SDK will automatically determine what zone to use. [Item #15720]
Added new GM_MapCatalogChangeMapOrder function to allow re-ordering maps in a loaded map catalog. [Item #15794]
Improved match on online source names for GM_LoadOnlineLayer function. The search for a matching source name is no longer case sensitive and also supports wildcards (like * and ?). [Item #15720]

Added support for Lidar with NIR (near infrared) sensor data. The following new functionality makes use of 4-band RGB+NIR LAS files [Item #15439]
- Three new draw modes were added, CIR for Color Infrared display of the 4-band data, NDVI for coloring points by the NDVI vegetation value, and NDWI for coloring points by the NDWI water value. [Item #15439]
- Automatic classification of high vegetation/building points will make use of the calculated NDVI/NDWI value to more accurately identify which points are high vegetation/trees and which are likely buildings. [Item #15440]
- The attributes for each Lidar point now include the NIR value as well as calculated NDWI and NDVI values. [Item #15439]
- Exports to Lidar LAS v1.4 files with color values included and input data with NIR values will write out the NIR data using LAS point format 8. [Item #15439]
- Grid calculated NDVI or NDWI values when creating an elevation grid from Lidar layers using the Analysis->Create Elevation Grid menu command. [Item #15447]
Automatically break up very large automatic Lidar classification and feature extraction operations in to smaller pieces so that the process can always do all work in memory. This allows automatically classifying much larger Lidar data sets without having to manually break the operation in to smaller pieces. [Item #14246]
Improved the default settings when automatically classifying Lidar points from high resolution Lidar scans (i.e. multiple returns per square meter). [Item #15440]
When selecting Lidar points in the path profile, the selected points are also automatically selected in the Digitizer Tool and highlighted on the main map view.
Allow changing the name to use for Lidar classifications by right-clicking on the classification on the Lidar tab of the Configuration dialog. Any exported LAS/LAZ files will also store the custom Lidar names in the header. You can also change the color assigned to Lidar points in that manner now as well. [Item #15357]
Added all Lidar class that aren’t reserved for ASPRS definition to the Favorites toolbar, including for keyboard shortcut assignment. This also includes any Lidar classes that have a custom name. [Item #15358]
Improved coloring (faster and more accurate) as ‘height above ground’ for high resolution/terrestrial Lidar data sets. [Item #15588]
Added ‘Don’t Ask Again’ checkbox on the prompt to confirm the change of classification of selected Lidar points from the Lidar toolbar (in the main view or the path profile) or from a Favorites option. [Item #15378]
Fixed issue with the Lidar draw selection of RGB/elevation on the path profile dialog using the current global setting rather than the RGB/elevation setting.
Made Alter Elevations options changes for Lidar point clouds be properly reflected when coloring by elevation and searching on the ELEVATION attribute. [Item #15551]
Fixed crash automatically classifying Lidar points from a map catalog with many large point cloud maps in it. [Item #15729]
When batch converting to LAS/LAZ 1.1 format files and checking to apply color from loaded imagery, bump the version up to 1.2 since color wasn’t added until that version. [Item #15745]
Fixed batch converting to LAS/LAZ format files and checking to apply color from loaded imagery when the projection in the main map view was different than that of the Lidar files being converted. [Item #15745]
When selecting Lidar points in the path profile, the selected points are also automatically selected in the Digitizer Tool and highlighted on the main map view.
When clicking to select Lidar points or add to the polygon selection for a Lidar path profile, allow clicks just outside the profile to make it easier to select points near the edge of the profile display. [Item #15426]

Data with recognized U/V vector components at a series of XY locations are also automatically loaded as a quiver plot, useful for things like ocean currents with velocity or directional wind speeds.
Added support for GGM Gravity Acceleration/Disturbance Grid Files (.ga, .dg, .xi, .eta, .ha extensions).
Added support for BIL (generic raster grid) files with 1, 2, or 4 bit samples.

LiDAR Changes

[LIDAR MODULE ONLY] Added support for Lidar with NIR (near infrared) sensor data. The following new functionality makes use of 4-band RGB+NIR LAS files [Item #15439]

[LIDAR MODULE ONLY] Automatically break up very large automatic Lidar classification and feature extraction operations in to smaller pieces so that the process can always do all work in memory. This allows automatically classifying much larger Lidar data sets without having to manually break the operation in to smaller pieces. [Item #14246]
[LIDAR MODULE ONLY] Improved the default settings when automatically classifying Lidar points from high resolution Lidar scans (i.e. multiple returns per square meter). [Item #15440]

[LIDAR MODULE ONLY] Improved coloring (faster and more accurate) as ‘height above ground’ for high resolution/terrestrial Lidar data sets. [Item #15588]
[LIDAR MODULE ONLY] Added ‘Don’t Ask Again’ checkbox on the prompt to confirm the change of classification of selected Lidar points from the Lidar toolbar (in the main view or the path profile) or from a Favorites option. [Item #15378]
Updated export of Lidar point clouds to vector formats, like Shapefiles, to not include the Lidar class name in the CLASS attribute. Where before you would get a CLASS value of ‘2 (Ground)’, you will now just get ‘2’. This allows for simpler searches and editing and smaller files.
Update the display and export of attribute lists for Lidar points to include SCAN_ANGLE and INTENSITY even when the values of those are 0.
[LIDAR MODULE ONLY] Fixed issue with the Lidar draw selection of RGB/elevation on the path profile dialog using the current global setting rather than the RGB/elevation setting.
Decoupled the point feature types for Lidar points from the Lidar class code filter for everything but styling. The point type filter on the Vector Display tab of the Configuration dialog no longer has any effect on what points will draw from a Lidar point cloud. Only the Lidar classification filter on the Lidar tab of the Configuration dialog affects that now. Previously you could inadvertently turn off the display of some Lidar classifications by turning off some point feature types. [Item #15379]
Added support for custom Lidar class names from LAS/LAZ files. Any custom type names are now displayed on the Lidar import dialog and on the Feature Info dialog when displaying information about a selected point. [Item #15591]
Updated search dialog to use the Lidar class name as the <Feature Type> value for points in Lidar point clouds rather than the name of the most similar Lidar point feature type. This allows custom Lidar class names to be displayed in the search dialog. [Item #15379]
Display point count and point density in Metadata dialog for map catalogs with Lidar point clouds in them. [Item #15729]
[LIDAR MODULE ONLY] Made Alter Elevations options changes for Lidar point clouds be properly reflected when coloring by elevation and searching on the ELEVATION attribute. [Item #15551]
[LIDAR MODULE ONLY] Fixed crash automatically classifying Lidar points from a map catalog with many large point cloud maps in it. [Item #15729]

[LIDAR MODULE ONLY] Fixed batch converting to LAS/LAZ format files and checking to apply color from loaded imagery when the projection in the main map view was different than that of the Lidar files being converted. [Item #15745]

3D Viewer Changes

When recording a fly-through video file, the video file will automatically be associated with the fly-through feature so you can easily play it back from the Feature Info or Digitizer Tool. [Item #15609]
Added option to play a video file synced with a selected line or point feature with time information. To do this, simply select the feature with the 3D Digitizer Tool, then right-click and select the ‘Play Associated Video File’ option. You will be prompted to select the video to play if a video has not already been associated. [Item #15609]
Fixed issue where fly-through frame rate would be accelerated for a short time after pause/resume.
Fixed a problem with shading on extruded objects. [Item #15190]
Lengths and areas reported in the 3D view now take elevations into account, if they’re present [Item #15245]
Added a new hotkey for use when measuring: pressing the Enter key operates the same as the right click menu option "Close polygon and stop measuring”.
Added a new hotkey, Ctrl+H, which toggles the mouse hover feature reporting behavior (which may be slow) on or off. This operation may also be performed using an entry on the 3D right-click context menu.
Fixed an issue where the 3D view zoom reverted to the default when switching from a scene that includes terrain to a scene that doesn’t. [Item #15247]
Added a new 3D navigational aid, the pivot axis, which shows the scene rotation pivot location. This may be toggled on or off using the 3D right-click context menu or by using the Ctrl+Shift+P hotkey.
Fixed an issue with selection in 3D allowing selection of points outside the scene boundary (which is governed by the 2D view). [Issue #15232]
Made several changes to mitigate lag when mouse hover mode is enabled. [Item #15158]
Added ability to lock the 3D mouse to either horizontal or vertical movement, when rotating the scene. To do this, hold down either the ‘H’ or the ‘V’ key while performing a rotation (e.g. When in Rotation mode, hold down the left mouse button and move the cursor; adding either ‘H’ or ‘V’ will lock the rotation to the horizontal plane or the vertical plane, respectively). [Item #15401]
Fixed an issue with rotated symbols in the 3D viewer [Item #15412]
Fixed an issue where notification text on the 3D view was hard to read. [Item #15647]

Path Profile/Line of Sight Function Changes

[LIDAR MODULE ONLY] When selecting Lidar points in the path profile, the selected points are also automatically selected in the Digitizer Tool and highlighted on the main map view.
[LIDAR MODULE ONLY] When clicking to select Lidar points or add to the polygon selection for a Lidar path profile, allow clicks just outside the profile to make it easier to select points near the edge of the profile display. [Item #15426]
Made the option to match the scale of the elevation and distance be remembered between dialogs rather than requiring re-entering that each time if you always want to match the scales.
Fixed display of crossing area/line features in a path profile when the default system elevation units are set to Statute (Feet).

Analysis Function Changes

Added option on the Shader Options tab of the Configuration dialog to select the method used to calculate slope values for the Slope Shader (and anywhere else slope is used). You can choose from the default method (Average Maximum of 4 Non-Diagonal Adjacent Samples) or 3 new methods, including the Average Maximum of all 8 Adjacent Samples, or an absolute Maximum Slope from the cell center to either the 4 non-diagonal adjacent cells or all 8 adjacent cells.
Improved accuracy of slope calculations on layers covering a large area using a lat/lon coordinate system or a highly distorted projection, like Mercator.
Updated calculation of view sheds from selected points to recognize additional attribute names to supply the view shed parameters. In particular, RADIUS can now specify the outer radius in kilometers, TRANSMITTER_HEIGHT specifies the transmitter height in meters (or feet with ‘ft’ in the string), RECEIVER_HEIGHT specifies the receiver height in meters (or feet with ‘ft’ in the string), START_ANGLE and SWEPT_ANGLE can be used to provide the angle range, and the COLOR attribute can specify the color to use. [Item #15485]
Updated calculation of area/line volumes with the Measure Tool to include the bounding box of the region being calculated so it is easy to find it from the pasted results.
Updated watershed calculation so that if multiple layers are created (i.e. stream lines, drainage areas, flow accumulation, and/or flow direction arrows), those layers are grouped together under the watershed name. [Item #15549]
Updated roughness grid calculation to not allow slope or slope direction shaders that don’t make sense and also to default the roughness grid layer to use its own shader rather than sharing the global one. This prevents the roughness grid values from affecting the coloring of other gridded layers. [Item #15777]
Fixed Flattened Pad Site creation option volume reporting and find optimum flatten height options. The volumes reported by the pad site flatten tool were not accurate.
Fixed bug causing the elevation units for a new grid layer to be set to Meters when Feet are selecting when gridding vector data. Bug in v16.0.0-v16.0.1, fixed in v16.1.1.
Fixed bug causing deleted holes/islands to still be cut out when creating terrain from 3D area features. This also made selection of areas fail when clicking inside a deleted island with the Feature Info or Digitizer Tool. [Item #15525]
Fixed bug causing generated watershed to not save to a workspace if the option to save the flow accumulation grid was also checked. [Item #15549]

Digitizer Tool Changes

Updated option to calculation point chainage along lines (connect points to nearest selected line feature) to have an option to provide a chainage offset (start distance) as well as an option to reverse the line direction when calculating chainage. Also made the calculated CHAINAGE and a SIDE_OF_LINE (‘L’ or ‘R’) attributes be added to the point feature as well as the created connecting line.
Added calculation mode setting that governs how the +, =, <=, <, >, >=, <> operations are performed. The mode can be set by a setting in the dialog box, or by the new CALC_MODE parameter for the CALC_ATTR_FORMULA script command. The calculation modes: Automatic: the operation is performed as numeric if both arguments are numeric, and as string otherwise; Numeric: the operation is performed as numeric; String: the operation is performed as string. [Item #15321]
Added option to ‘Invert Selection’ to the Digitizer Tool right-click Advanced Selection submenu.
When adding measure attributes to rectangular area features, add LENGTH and WIDTH attributes for the length and width of the rectangle. These attributes are now also displayed for rectangular features on the Display Feature Measures dialog if any of the selected areas are rectangular.
When creating distance/bearing/COGO lines and using the COGO field entry, adding a point (with Enter or by clicking ‘Add Point’) automatically selects all text in the COGO field and sets focus to that field so you can immediately type the next COGO entry. [Item #15415]
Added option to play a video file synced with a selected line or point feature with time information. To do this, simply select the feature with the Digitizer Tool, then right-click and select the ‘Play Associated Video File’ option. You will be prompted to select the video to play if a video has not already been associated. [Item #15609]
Improved connecting of line features to form longer lines or area features so that the elevation is taken in to account. This allowed correctly selecting from multiple lines to find the best one to follow based on the Z value. [Item #15531]
Fixed issue with distance/bearing/COGO line creation crashing in v16.1.0.
Fixed selection of areas within selected areas that caused areas that were inside an area but partially inside a hole/island of that area (but not completely inside the hole) to also be selected.
Fixed creation of point features at grid cell centers when creating a regular grid of features when that is the only creation option checked. [Item #15503]
Made created range rings use the font selected on the range ring dialog. [Item #15539]
Fixed copy of attributes from points to areas so that if you select to keep the minimum or maximum value when multiple points are present that actually happens. [Item #15535]
Fixed creation of min/max elevation points from terrain inside selected areas when the area layer uses a different projection than the current view projection. [Item #15723]

Scripting Changes

New command: GENERATE_VIEWSHED to perform a view shed analysis using loaded elevation grid data with a user-specified transmitter location, height, and radius. All areas within the selected radius that have a clear line of sight to the transmitter are colored with a user-specified color. [Item #14993]
New command: GENERATE_RIDGE_LINES to find ridge lines from loaded terrain data. This command uses the same parameters as the GENERATE_WATERSHED command as internally they are nearly the same operation. [Item #15703]
Updated the LOAD_PROJECTION command to allow automatically selecting the best zone for zoned projection systems, like UTM, or to specify the name of a known grid system with no parameters, like SWISS_GRID. To do this, either use the old-PRJ format in the DEFINE_PROJ command with a ZONE value of 0, or simply provide the name of a built-in zoned projection in the PROJ parameter for LOAD_PROJECTION. For example, LOAD_PROJECTION PROJ=”UTM” will set the projection to a UTM projection with the datum and units of the current projection and the best zone for the center lat/lon of all loaded data. [Item #15548]
Support changing the algorithm used for slope calculation with a new SLOPE_ALGORITHM parameter for the SET_VERT_DISP_OPTS command.
Added support for using %TIMESTAMP_MS% as a variable inside a script. This will embed the current time with millisecond resolution in the format ‘YYYYMMDD_HHMMSSsss’ (where SSsss is 2 seconds digits and 3 millisecond digits). Use to uniquely tag filenames or other values to millisecond resolution.
Added support for using a polygon crop file to only select which grid/tile cells to export, while not cropping within the cells that overlap the crop file. To get this behavior in any script command that supports both polygon crop and gridding, add POLYGON_CROP_GRID_ONLY=YES to the command.
Added EDIT_VECTOR parameters ATTR_EXISTS and ATTR_MISSING to allow features to be selected based on whether or not an attribute exists. [Item #15436]
Updated EDIT_VECTOR command so that any newly created layers from that command (i.e. from NEW_LAYER_NAME parameter) will use the code page of the original layer. [Item #15465]
Added control of the ‘use 4 point polynomial’ option for rectification via a RECTIFY_4_POINT_POLY_ONLY parameter. The setting is now saved on a per-layer basis in workspaces rather than being a global setting per computer. [Item #15557]
When getting a file extension and name w/o extension (i.e. %FNAME_WO_EXT% for DEFINE_VAR command), treat .tar.gz as the full extension and not just the .gz. [Item #15603]
Added support for adding a list of files from an external text file to a map catalog using the new ADD_FILE_LIST parameter for the EDIT_MAP_CATALOG command. [Item #15783]
Updated EXPORT_VECTOR command export to Wasp .map to default the DISCARD_ISLANDS parameter to NO rather than YES to match exports from the user interface by default. [Item #15626]
Fixed handling of EXPORT_DWG_LABELS and EXPORT_DWG_LABELS for EXPORT_VECTOR command. The new values ATTRS, FEATURE_LAYER_POINTS, and LABEL_POINTS weren’t recognized.
Fixed crash in v16.1.0 using the EXPORT_VECTOR or APPLY_FORMULA script command with a polygon crop file.
Fixed error in v16.1.0-v16.1.1 using the IMPORT_ASCII script command with no TYPE parameter. It should default to TYPE=POINT_AND_LINE if not provided.
Fixed bug with SPLIT_AT_INTERSECTIONS parameter for the EDIT_VECTOR command not adding the new split lines. The original lines that would have been split were just marked as deleted.
Fixed bug in EDIT_VECTOR where COMPARE_STR="<attr_name>=*" was matching features that do not have an attribute called <attr_name>. [Item #15434]
Fixed string replacement and comparisons using accent characters against layers using UTF-8, like OpenStreetMaps XML layers. [Item #15465]

Online Source Changes

Added support for WFS 2.0.0 sources and some other WFS sources that weren’t working. [Item #15600]
Added built-in online sources for the ‘Atlas of the Cryosphere’, providing polar data like snow and ice cover for various years. These sources are under the new ENVIRONMENT built-in group on the online source dialog. [Item #15455]
Added built-in online sources for NSW Australia Imagery and Base Map data under the COUNTRY DATA->Australia group. [Item #15725]
Removed old ASTER GDEM source from Popular Sources and Worldwide data (now only in Terrain Data) as it is very unreliable and should almost never be used instead of the ASTER GDEM v2 source.
Updated web page display dialog to be resizable when getting information from a loaded WMS source with the Feature Info Tool. [Item #15796]

Projection/Datum Changes

Allow saving the EPSG AUTHORITY tag in saved PRJ files. You must have the "Include Datum Parameters & EPSG Codes in WKT PRJ Files" option in the Advanced section of the General tab of the Configuration dialog checked for this to be saved. It is not enabled by default because some versions of Esri products are not smart enough to handle PRJ files that include the AUTHORITY. This option also turns on inclusion of datum transformation parameters in exported PRJ files (another problem [Item for Esri products). [Item #15787]
Added built-in datum and ellipsoid for ‘International 1924 Authalic Sphere’. These are used with the EPSG codes 3408 and 3409 and NSIDC EASE-Grid systems for the North and South Pole. [Item #15455]
Added built-in EPSG codes for Louisiana State Plane projections with US Survey Feet. [Item #15489]
Added additional built-in EPSG codes for Illinois State Plane / NAD83 HARN and NSRS2007. [Item #15758]

Format Specific Changes

Significantly sped up display and export of JPEG2000 and MrSID files that are aligned with external files or rotated, particularly when zoomed out further than full resolution for the layer. [Item #15358]
Updated ECW export to save a known EPSG code for the export projection if no known datum code is found but an EPSG code is. This allows the Web Mercator projection and NAD83 HARN/HPGN systems to be maintained exactly. [Item #15385]
Improved export of display labels to DWG files. Now text color and alignment is maintained and multi-line text is properly aligned.
Updated CADRG/CIB data so that the zoom level at which the frame bounding boxes appear rather than the actual data is controlled by the zoom level settings for each layer. You can right-click on the a.toc layer in the Control Center and select which zoom levels to display the data at. [Item #15633]
Updated VPF (VMAP/DNC) import to allow selecting what to load down to the feature class level rather than just selecting coverage libraries to load.
Updated VPF (VMAP/DNC) import to have a ‘Use for All’ checkbox on the category/tile selection so you can remember which types are disabled for all loads in the current command, like batch conversion and not be prompted for each file.
Improved display speed of KML/KMZ files that reference a large number of images.
Updated KML/KMZ export to split lines in to segments of no more than 8,092 vertices to ensure that Google Earth can display them properly.
When exporting 3D areas marked as ‘Extruded’ to KML/KMZ files, only add side wall 3D area features if there is an explicit 3D_EX_HT attribute to create a 3D volume. Extrusion to ground level is handled by the <Extrude> tab. [Item #15688]
Updated map catalog handling to keep more off-screen maps loaded if a lot of memory is available. This prevents extra loading/unloading as you pan and zoom around. [Item #15353]
Allow batch converting from map catalog files. When you add a map catalog, the individual maps from the catalog are added to the list of files to convert. [Item #14078]
Support reading elevation units from Erdas IMG files that include that information. If present those files are also automatically interpreted as elevation rather than prompting the user. The vertical datum is also added to the layer metadata as a VERT_DATUM value if present. [Item #15717]
Updated elevation TIFF import to prompt the user for elevation units if we can’t automatically determine them from the header rather than assuming meters. [Item #15717]

Added option on the Shader Options tab of the Configuration dialog to select the method used to calculate slope values for the Slope Shader (and anywhere else slope is used). You can choose from the default method (Average Maximum of 4 Non-Diagonal Adjacent Samples) or 3 new methods, including the Average Maximum of all 8 Adjacent Samples, or an absolute Maximum Slope from the cell center to either the 4 non-diagonal adjacent cells or all 8 adjacent cells.
Added built-in NDWI shader for coloring NDWI (Normalized Difference Water Index) calculated values. This shader is automatically used when you apply a NDWI formula to multi-spectral raster imagery or display 4-band NIR Lidar data with the new NDWI Lidar draw mode. [Item #15439]
Made cancel of draw with Esc key press much more responsive for large raster layers, especially, ECW, JPEG2000, and MrSID. [Item #15368]
Updated live video tracking from a selected feature in the Feature Info Tool to keep the video playback location on the screen if the GPS menu option to ‘Keep the Vessel On-Screen’ is enabled. The current video playback location is also now displayed using the same icon as the GPS is set to use and will also be oriented how the line being tracked is oriented. [Item #15375]
Added new ‘Aerial Coverage’ built-in area type. [Item #15375]
Fixed zoom with mouse wheel when the view is rotated. The view would zoom correctly but the location under the cursor would not stay fixed in place.

Misc. Changes

Added numeric rounding functions: FLOOR(num), CEILING(num), TRUNCATE(num), MOD(numerator, denominator). Also added ISNUM function: ISNUM(str): returns true if str denotes a floating point value, and false otherwise, new regex function FIND(str, regex): returns 0-based index to start match in str if the regular expression matches, -1 otherwise, new string concatenation function: CONCAT(str [, str]*) : concatenate the arguments to form a single string: e.g. CONCAT(“a”, “b”, “c”) evaluates to “abc”, and allow MIN/MAX functions to take multiple arguments: e.g. MAX(1, 2, 3) evaluates to value 3. [Item #15611]
Added trig functions: SIN(radians), COS(radians), TAN(radians), ASIN(num), ACOS(num), ATAN(num), DEGTORAD(degrees), RADTODEG(radians), plus the constant PI. [Item #15293]
String comparison additions: new operator ‘~=’ that performs case-insensitive string comparison (e.g. “abc” ~= “ABC”); returns true of the strings are equal, and false if not, plus COMPARE(str1, str2), and COMPARENOCASE( str1, str2), which perform case-sensitive and case-insensitive string comparison, returning 0 if the strings are equal, a negative number if str1 is less than str2, and a positive number if str1 is greater than str2. [Item #15694]
Added calculation mode setting that governs how the +, =, <=, <, >, >=, <> operations are performed. The mode can be set by a setting in the dialog box, or by the new CALC_MODE parameter for the CALC_ATTR_FORMULA script command. The calculation modes: Automatic: the operation is performed as numeric if both arguments are numeric, and as string otherwise; Numeric: the operation is performed as numeric; String: the operation is performed as string. [Item #15321]
Allow cropping and tiling to selected closed line features for exports and other operations that allow cropping/tiling. Previously you could only crop to selected areas, not closed lines. [Item #15413]
Added option to reverse the order of selected maps on the Control Center right-click menu.
Update graph display for vector layers/features to support treating attribute values with text after a starting number, like a degree symbol after a slope, as numeric values for graphic purposes. [Item #15420]
Made case-insensitive searches using accented characters work. [Item #15465]
Made the Batch Convert/Reproject dialog resizable.
Update GPS Setup dialog to only show COM ports that are actually available on the system and to also show the friendly name for the COM port (if any) rather than just COM1, COM2, etc. The auto-detect will also check named COM ports for a recognized data signal before un-named ones, with those with Garmin in the name taking the highest priority. [Item #15583]
Fixed issue when displaying/exporting feather-blended terrain layers when multiple terrain layers overlap at a single location where feathering is applied. The wrong underlying terrain was being used in some cases to blend with the top-most terrain.
Fixed crash in v16.1.0 when “Apply settings from previous feature” button on Modify Feature dialog clicked and previous feature does not use the default font.
Fixed load of point types/styles from .gm_style files to read in default attribute lists if present. They were previously saving to .gm_style files, but not loading.

What's New in Global Mapper v16.1

SDK-Specific Changes

Added new GM_GetOnlineSourceInfo function to get detailed information about an online source and also see if the server is available. The lat/lon bounding box of the source is retrieved with this call.
Added ability to set the temporary folder used by SDK operations using the GM_SetMiscOptionEx function with a new option code GM_MiscOpt_SetTempFolder.
Added support for adding online sources from a file by passing the full path and filename as the source name via the GM_LoadOnlineLayer function. Subsequent calls to that function can then load from those sources.
Added support for providing the projection for the aLatLonBounds parameter to the GM_LoadOnlineLayer function so that you can specify the bounds to load in a projection other than lat/lon in the current projection datum. A new BOUNDS_PROJ parameter in the extra load flags for the function allows this. See documentation for more details.
Updated Windsim GWS export to automatically detect which layers are roughness grid layers, removing the need for passing in the ROUGHNESS_LAYER_LIST value in the extra load flags if the roughness grid was created by the SDK.
Fixed error in v16.0.0-v16.0.5 calling GM_MapCatalogCreate.
Fixed crash calling GM_GetAreaFeatureEx with the GM_DontGetPolylineCoords flag on areas with islands/holes when you subsequently call GM_FreeAreaFeature to free the memory.

Significant New Features

Sped up online sources by downloading data in the background. The display and export of online sources is now several times faster in many cases. You can also immediately cancel the drawing of any online source by pressing Escape without having to wait for the server to respond.
Added ability to select features in the 3D viewer. This is a new mode initiated by selecting the selection tool on the 3D viewer toolbar. Any selections are shared by both the 2D and 3D viewer, and the right-click menu allows you to perform operations on the selection.
Added Measure Mode to the 3D viewer. This is a new mode initiated by selecting the Measure tool on the 3D viewer toolbar. Measurements are shared by both the 2D and 3D viewer, and the right-click menu allows you to perform operations on the selection.
Added option to rotate the map view under the View menu. The new menu command allows you to easily rotate the map view to whatever angle you want. You can also use Backspace to rotate the view counter-clockwise.
Added option to automatically rotate the map in whatever direction a connected GPS device is pointing. This new option under the menu allows you to use ‘track up’ mode when connected to a GPS so that forward is always to the top of your display.
Added option to display a video file synced to any line feature with per-vertex times or point features with recognized timestamp attributes. This option is available on the right-click menu of the Feature Info dialog whenever times are found. This allows you to easily play a video file that tracks a line feature and sync up the playback and the location on the map.
Updated the Control Center CALC ATTR dialog (Attribute Calculation Setup) with the ability to calculate new attribute values using spreadsheet-like formulas. The new attribute formulas allow numeric, Boolean and string operations, using standard mathematical notation and predefined functions, which include sophisticated text match, search and replace operations using regular expressions.
Numerous scripting updates, including exporting from specified layers, cropping export to a polygon selected in the user interface, a SET_OPT command to define general options and type filters, and support for using formulas when calculating attribute values (new CALC_ATTR_FORMULA command) and defining variables.
Improved exports using image-optimized palettes for data with more than 256 colors but large areas with the same color.

LiDAR Module Only Highlights

Allow cropping Lidar points to selected area features when automatically classifying.
Default NO_DATA_DIST_MULT value when generating a bin grid with the GENERATE_ELEV_GRID script command to use a value of 6 for filling gaps rather than 0 which is more appropriate as a default for traditional TIN gridding.
Improved automatic classification of high vegetation (trees) from point clouds with lots of high return count (3 or more) points, such as highly forested areas.
Improved assigning of elevation values/attributes when extracting building outlines from classified Lidar data. Also added MAX_ELEV and MIN_ELEV attributes to capture the minimum and maximum elevation of any points used in the building.
Fixed extraction of separate roof pieces when performing building extraction in a projection using linear units other than meters.
Fixed issue with option to filter which Lidar points are considered when gridding a Lidar point cloud not working when doing a TIN grid rather than one of the binned grid methods.
Fixed issue with Lidar points not deleting properly in the Lidar path profile view.
Made automatic classification of Lidar points in map catalogs work. You will want to immediately export the results as the modified Lidar data will be unloaded without saving if the catalog no longer needs them for display.
Support using SPATIAL_RES_METERS for any operation that used GRID_BIN_SIZE for binned Lidar gridding or other Lidar operations.

New Supported Formats

Fixed crash exporting to LAS/LAZ when the current projection doesn’t have a known exact EPSG code.
[LIDAR MODULE ONLY] Made automatic classification of Lidar points in map catalogs work. You will want to immediately export the results as the modified Lidar data will be unloaded without saving if the catalog no longer needs them for display.

3D Viewer Changes

Added ability to select features in the 3D viewer. This is a new mode initiated by selecting the selection tool on the 3D viewer toolbar. Any selections are shared by both the 2D and 3D viewer, and the right-click menu allows you to perform operations on the selection.
Added Measure Mode to the 3D viewer. This is a new mode initiated by selecting the Measure tool on the 3D viewer toolbar. Measurements are shared by both the 2D and 3D viewer, and the right-click menu allows you to perform operations on the selection.
Add option to create a fly-through path from selected line features when using the fly-through controls in the 3D view and no pre-defined fly-through paths are available.
Added fly-through pause toolbar button.
Fixed skybox zoom issues.
Fixed issue where some fly-through avi files were not playable. Allow larger compressed avi files.
Fixed issue where fly-through avi compression options were not available in 64-bit version.

Path Profile/Line of Sight Function Changes

Added the 3D segment and total distance to a CSV file for a 3D path saved from the File menu on the Path Profile/LOS dialog.
Change display of separate lines for multiple overlapping terrain layers to not draw any line for the layer where it does not have valid values rather than drawing a straight line connecting regions with valid elevations.
Limited the available formats when exporting the rendered path profile to a vector format to only include those formats that support non-spatial data, like PDF or CAD (DXF, DGN, DWG, etc.) formats.
Fixed issue with the cursor displayed on the path profile dialog changings to an arrow.
Fixed issue with the option to draw crossing lines on the path profile not being remembered properly.

Analysis Function Changes

Added option to Watershed calculation to create a flow direction point layer with a selected symbol. This allows you to quickly create a quiver plot showing the flow direction and quantity on a terrain surface.
Made the Advanced option to snap bounds to an even multiple of the export spacing also apply when generating an elevation grid from 3D vector/Lidar data, both from the user interface and using the GENERATE_ELEV_GRID script command.
Fixed major issue in volume calculations (any type other than a range of elevations) when the default vertical units are Statute (Feet) rather than Metric (Meters). The results were off by the conversion factor from feet to meters (about 3.28) before this fix.
Ensure volume results when doing a single cut height are the same as for a range of cut heights. Also show 3D surface area when doing a single cut height.
Improved precision of generated contour labels when creating contours with a very small (<0.1 meters/feet) contour interval.
Added option to select the volume units when measuring the volume between surfaces.
Fixed bug in v16.0.0-v16.0.3 with area features used as obstructions in view shed calculations making everything not blocked by the areas visible.
Fixed issue with contrast adjustment automatically being enabled for all multi-band images created by the Raster Calculator and not just those with more than 8 bits per band.
Fixed crash gridding point data sets while cropping to a selected area feature.

Digitizer Tool Changes

The CALC ATTR dialog (Attribute Calculation Setup) may now be invoked on the current feature selection. This option is accessed from the “Attribute/Style Functions” submenu in the right-click menu for selections.
Added “Cut Selected Area(s) from all Overlapping Areas” option. Similar to exiting “Cut Selected Area(s) from Another Area” function, except all areas in specified layers are processed rather than a single layer.
Cropping to selected areas will automatically fix any invalid area geometry when they cause the crop to fail. This will allow many more crop operations to complete without error without needing to manually find and fix invalid polygons before doing the crop. In addition any exports to selected areas will also fix invalid polygons that cause the crop to fail.
Updated creation of strike-and-dip points to visually show the orientation of the point as you drag after left-clicking to much more easily get the desired orientation of the strike/dip. The dip and strike angle are also now displayed on the status bar as you drag with the left mouse button down.
Invalid area geometries where an island is on or outside of the parent are now automatically fixed by the invalid polygon detection and fixing tool.
Added support for copying attributes from points to other nearby point features using the Copy Attributes option in the Digitizer Tool.
Added “Edit Feature Vertices” option under Vertex Editing right-click sub-menu of Digitizer Tool. This allows displaying and editing the vertex list (including per-vertex elevations and times) of any single selected line or area (including hole/island) feature.
When creating lines connecting point features to line features, rename the DIST_ALONG_LINE attribute to CHAINAGE to reflect the more common usage.
Add option to select the native projection for a new layer created from the feature edit dialog. This allows moving/creating new features in a layer with a custom name and whatever projection is desired.
When creating point features from a line feature with per-vertex time-stamps, add SPEED, AVG_SPEED, and ELAPSED_TIME attributes. Do the same if adding from the Feature Vertices dialog for selected points.
Added option to disable the selection of holes/islands in area features when clicking/dragging to select. The option is under the right-click Options menu in the Digitizer Tool.
Updated creating of perpendicular lines to selected lines to add the non-measure attributes of the line/area to the perpendicular lines.
Updated calculation of area elevation statistics to more often determine a predominate slope aspect and report that as an ASPECT attribute. In addition the average slope direction will always be added as an AVG_ASPECT attribute even if there isn’t a dominant direction.
Fixed issue with the orientation of the last line when creating perpendicular lines to selected lines.
Fixed selection of layer in the feature edit dialog when multiple features are selected for editing.
Fixed crash creating new features in a layer other than User Created Features if nothing in User Created Features and auto-save backup workspaces option checked.
Fixed issue with option to chop up areas to reduce the vertex count not always being available if multiple areas are selected.
Fixed issue with option to chop up areas to reduce the vertex count not always reducing all the way to 3 vertices if you want to create triangles from the areas.
Added units of arc seconds and arc minutes for creating a regular grid of features.
Fixed issue with using the Edit->Select All menu command or the right-click Select All Features in Layer option in the Control Center selecting features in the Digitizer Tool that are disabled for selection, such as is if you turned off selection of lines.
Added Create Buffer option to list all attribute values of combined areas, which has been the default behavior, or simply assign a single representative value to each attribute instead.
Fixed issue where square buffers would sometimes have incorrect shape near start/end vertices.

Scripting Changes

Added support for exporting only specific layers from an EXPORT script command. You can now add one or more EXPORT_LAYER parameters to an export command and only those layers that match one of the EXPORT_LAYER filters will be exported.
Added support for exporting everything outside of selected polygons rather than inside by adding POLYGON_CROP_EXCLUDE=YES to any script command where you are cropping to one or more polygons.
Added support for cropping a script EXPORT* command to an area feature selected in the Digitizer Tool. Just add POLYGON_CROP_NAME=”SELECTED” to the command parameters to use any selected area feature(s) from the user interface in the crop.
Updated EDIT_VECTOR command to allow filtering what is operated on to a bounding box. Any of the normal bounding box parameters (i.e. LAYER_BOUNDS, GLOBAL_BOUNDS, LAT_LON_BOUNDS, etc.) are applicable.
Added support for setting a large number of advanced options with the SET_OPT command using new MISC_OPT and MISC_OPT_VALUE parameters. This includes global settings for the snapping of export bounds to pixel or spacing boundaries and maintaining export bounds over sample spacing. You can also set the base temporary files folder used by Global Mapper. See documentation for complete list of options.
Added support for more built-in variable names to allow easily logging the time required for scripts to run. Now %TIME_SINCE_START%, %TIME_SINCE_LAST_LOG%, and %SCRIPT_FILENAME% are available as built-in variables. You would likely use them with the LOG_MESSAGE command.
Added facility for calculating new attribute values using formulas using the new CALC_ATTR_FORMULA script command. The CALC_ATTR_FORMULA is similar to the existing CALC_ATTR formula, except that that you can specify new attribute values using formulas. See the documentation for more information, including a description of attribute formulas.
Added support for new script variables using formulas in the DEFINE_VAR script command. There is now a FORMULA parameter that accepts a formula for assigning a value to a script variable. See the documentation for a more complete description of variable formulas.
Updated export bounds when cropping operations to polygon features. By default, the export bounds will be the intersection of the crop area bounds for the operation and the data export bounds (either default all-data or the explicitly provided bounds). You can also provide a POLYGON_CROP_INT_DATA_BOUNDS=NO parameter to indicate that the export bounds should be the crop area bounds unless you explicitly listed another bounding box (i.e. GLOBAL_BOUNDS or LAYER_BOUNDS parameter), in which case that explicit bounding box will be used.
Support exporting unsigned 16-bit and signed/unsigned 8-bit values with the BIL and GEOTIFF type export with the EXPORT_ELEVATION command. The new USE_UNSIGNED parameter is used to specify that unsigned values should be exported.
Moved type filter functionality to SET_OPT command and deprecated the LOAD_TYPE_FILTER command. It will still work, but any new global options will be part of the SET_OPT command.
Added support for specifying a Lidar return filter both for global display and export with SET_OPT as well as for individual IMPORT and EXPORT commands with a new LIDAR_RETURN_FILTER parameter.
Updated EDIT_VECTOR command to allow just providing a NEW_LAYER_NAME parameter to allow creating any new features from the command in a layer with that name rather than placing them in the layer of the feature(s) they were created from.
Updated EDIT_VECTOR command to support resampling line or area feature vertices by distance using the RESAMPLE_FEATURES parameter.
Added support for copying attributes from points to other nearby point features using the COPY_ATTRS script command.
Support wildcards in the FILENAME parameter for an IMPORT command to allow easily loading all files that match a particular wildcard string, like FILENAME=”*.tif” to load all TIFF files in a folder.
Support NOT recursing sub-folders when using the IMPORT_DIR_TREE command to load files matching a mask string. Now add RECURSE_DIR=NO to the command to only load files in the specified folder.
Added the GRID_OVERLAP_NUM_PIXELS parameter to indicate whether or not the value specified in GRID_OVERLAP should be interpreted as the number of pixels (EXPORT_RASTER command)
Added new command SHIFT_LAYER to move one or more layers by the specified offset distance.
Added support for using the default position and/or projection when loading a layer and that data cannot be automatically determined by adding USE_DEFAULT_POS=YES and/or USE_DEFAULT_PROJ=YES to an IMPORT command.
Added support for setting the vector detail offset (slider from Vector Display tab of Configuration dialog) with a DETAIL_OFFSET parameter for the SET_OPT command.
Added support for hiding any windows that would be shown by a RUN_COMMAND command. Add HIDE_WINDOW=YES to the command to hide the window.
Allow layers to be specified with just a filename with no path rather than requiring a full path or wildcards. Applies to any command where you provide the filename/description of a layer to work on.
Added nested progress dialogs when running a script which loops over a set of files or layers providing much better monitoring of the script progress and allowing simpler cancel.
Added support for specifying the altitude mode for elevations in a layer with an ALT_MODE parameter for an IMPORT or SET_LAYER_OPTIONS command.
Added support for creating a flow direction point layer with the GENERATE_WATERSHED command by adding GEN_FLOW_DIR_POINTS=YES. This layer will have points for each sample location showing the flow direction and magnitude.
Allow specifying the CODE_PAGE for KML vector and GPX exports with the EXPORT_VECTOR command. The default is to use the UTF-8 code page.
[LIDAR MODULE ONLY] Support using SPATIAL_RES_METERS for any operation that used GRID_BIN_SIZE for binned Lidar gridding or other Lidar operations.
Provide more options for label export to DXF/DWG files using the EXPORT_VECTOR command. Now the EXPORT_DWG_LABELS/EXPORT_DXF_LABELS parameters support exporting features labels as attributes, separate points on the features’s layer, or separate points on a label layer. The existing Yes/No support still works as before.
If you explicitly provide bounding box parameters for a command and also crop to one or more polygons, the explicitly provided bounds are used rather than the bounds of the crop polygon(s).
Fixed issue with EDIT_VECTOR command not doing anything if no COMPARE_STR parameter were provided (in v16.0.0-v16.0.3).
Fixed bug passing variables on the command line in v16.0.0-v16.0.3.
Fixed crash using EXPORT_VECTOR command with %SPLIT_ATTR% in the FILENAME parameter in some v16.0.x builds.
Fixed issue with EXPORT_RASTER command that caused the display bounding box in the main application view window to change after running the script in some cases.

Online Source Changes

Sped up online sources by downloading data in the background. The display and export of online sources is now several times faster in many cases. You can also immediately cancel the drawing of any online source by pressing Escape without having to wait for the server to respond.
Added option to create world files for each downloaded tile from an online tiled source. This allows you to directly load the files in to Global Mapper from the local cache, which is especially useful if you create a map catalog for offline use of the data. The option is found in the Advanced section of the General tab of the Configuration dialog
Added support for finding the location associated with a MapCode (www.mapcode.com). The Search->Find Address menu command allows specifying a MapCode as the location to find.
Added Mexico layers from INEGI as built-in sources under the new COUNTRY DATA group. This includes orthophotos and many other types of data covering Mexico.
Added CORINE Land Cover 2006 (100m Resolution) as built-in online source. The previous CORINE online source was from 2000. That is still available as well. The new source can be used for roughness grid/area calculations.
Added FEMA Hazard maps as built-in online sources. Both the WMS (Raster) and WFS (Vector) FEMA sources are available under the U.S. Data group and provide flood and other hazard maps for the entire U.S.
Added built-in link to ESA CCI Soil Moisture global database. This is just a website link so you still have to download the actual data you want and then load it.
Allow easily adding multiple sources at once from a WFS server. You can now select more than one feature when adding a WFS source. If multiple are selected, you get a separate source for each selected feature.
Added right-click option to save any selected online source definitions to a XML file to the online source dialog. This allows easily exporting user-added source definitions to load on another machine and add to that machine’s source list.
Added new option to Add Source dialog when adding a WMS source to allow preferring the use of WMS v1.1.1 rather than whatever the source reports as the default version (i.e. v1.3) if desired. This is useful as some servers don’t properly handle the axis order as the WMS v1.3 specification requires for some coordinate systems.
Allow removing multiple selected sources at once from the online source download dialog. If you have selected a group of source and none of them are built-in sources, they will all be removed when you use the ‘Remove Source’ button.
Improved automatic selection of a SRS (projection) to use for WMS sources with a large list of available projections.
Fixed issue with Brazil Topo Maps source no longer working.
Fixed issue with right-click on source list causing multiple [Items to be selected.

Projection/Datum Changes

Improved speed of reprojection in some cases, particularly map catalogs with a large number of maps to reproject. This was slower in v16.0.0-v16.0.3 than it needed to be.
Fixed issue with small missing sliver near anti-meridian (+180/-180) when reprojecting data that crosses the ATM to Geographic (lat/lon). This affects both display and export to formats that force the projection to lat/lon, like KML/KMZ.
Added built-in EPSG code for MOLDREF99 (EPSG:4026).
Added built-in EPSG codes for Idaho State Plane projections using NAD83 (NSRS2007).
When changing projections on the projection selection dialog and the new projection doesn’t allow the previously selected datum, default to the first datum in the allowed list for the new projection rather than keeping the dis-allowed datum.
Fixed issues with some reprojected maps being cropped when the original bounds go slightly outside the valid bounds, like a Mercator map with a corner that goes just slightly west of -180 or east of +180 with a map centered on 0.

Format Specific Changes

Restored ESRI File Geodabase (FDGB) load to 32-bit Global Mapper with no ESRI license (only for Windows Vista and later).
Added Band Setup tab to Options dialog for multi-band PNG image layers, allowing re-ordering the bands and also disabling the alpha channel.
Updated GPX export to allow including elevations and timestamps in track log (line) exports, descriptions and symbols for export waypoint features, and to choose character encodings other than UTF-8 and ISO-8859-1.
Fixed issue rendering dashed lines in PDF layers in v16.0.0-v16.0.3.
Sped up the load of VPF format data (i.e. VMAP0, VMAP1, etc.).
Added support for loading SHP files over 4GB in size.
Improve load and display of text from XML files that is in a language (code page) other than the current system code page. For example you can now load OSM data with Cyrillic/Korean/Chinese/etc. text and display on an English language Windows machine.
Made DXF export store text justification tags so that text placement is preserved based on what was selected in Global Mapper.
Improved export of ECW and JPEG2000 files when using a projection with International Feet for the units (typically a State Plane projection). The coordinates are no longer converted to US Survey Feet but instead kept as International Feet. The State Plane projection default units for the zone or an external .prj or .aux.xml will be used on import to determine if the file coordinates should be US Survey Feet or International Feet since the ECW format doesn’t have separate unit codes internally for the different flavors of feet.
Fixed issue in DXF export with duplicate POINT and TEXT entities being exported at the same location in some situations when the point feature only has text and no symbol.
Added “Add ELEVATION Attribute” option to batch conversion to Shapefiles.
Added option to export unsigned 16-bit samples for BIL and GeoTIFF elevation exports. There is now an option next to the select for 16-bit elevation export to choose Signed or Unsigned. Previously only signed 16-bit values could be exported.
Update map catalogs to not draw map bounding boxes if zoomed in too far to draw the map when you have the display set up to a range of scales/sizes.
Sped up changes to the map list for very large map catalogs, including sorting the maps and saving modifications.
Automatically use 24-bit RGB PNG files in raster KML/KMZ export if an output file has 256 or more colors. Otherwise a palette-based PNG will be used.
Improved sorting of layers by resolution for map catalogs and when sorting from the Control Center right-click menu, especially for maps in polar regions.
Added progress reporting and option to cancel when embedding large layers in a workspace and exporting large vector layers to a Global Mapper Package (GMP) file.
Corrected progress reporting when loading a workspace file over 4GB in size.
Updated Platte River/Geographix export to use proper number of digits for township and range.
Updated DXF export to include TABLES section at the top to fix problems loading in software that requires that section.
Fixed more issues loading some XTF files with bad ping values.
Improved accuracy of OTF elevation grid.
Made KML/KMZ files that reference images load properly as a map catalog rather than loading as a non-functional map catalog layer and separate working image layers that are always displayed.
Fixed issues loading some Trimble GGF Geoid, including rotated and flipped grids.
Don’t export empty Shapefiles if no features intersect the clip area(s)/bounds. Previously if you exported to a Shapefile and some features had bounding boxes that intersected the clip area(s)/bounds, you would get a file even if none of the features actually intersected the clip area(s)/bounds.
Fixed bug with the attributes loaded from text files without a blank line between features. The first attribute from each feature could be assigned to the previous feature.
Support DGN files with 3D holes/islands in 3D area features. Previously the per-vertex elevations for the holes were not being used.
Save some settings on the Generic ASCII import dialog between runs, such as coordinate order, import type, and coordinate prefix.
When loading multiple ESRI File Geodatabase (gdb) files (or adding to a map catalog), add a ‘Use for All’ button on the table selection dialog so you can load the same set of tables from each GDB being added.
Import benchmark point features when loading Trimble Field Survey XML files.
Made generic ASCII text import with ‘Auto-Detect’ or ‘Space or Tab’ delimiter prefer tab over space so that tab-delimited files with spaces in the coordinate fields can be correctly loaded without having to select ‘Tab’ explicitly.
Fixed issue with exported CADRG/CIB files not working in some software that required a particular ordering of the components in the frame files. Now frame files should order the data internally the same way other CADRG data sets do.
Fixed issue with missing tiles when exporting from map catalogs to PNG files, including as part of a web export.
Fixed problems loading some NetCDF files with time-dependent variables.
Fixed storing of Web Mercator projections in JP2 exports.
Fixed issue in v16.0.0-v16.0.4 with some rare JP2 files being rotated and incorrectly positioned.
Fixed issue in v16.0.0-v16.0.4 with some OCAD files with spline curves failing to load.
Fixed issue with S57 file loads showing warning messages about ignored or mis-placed attributes.
Fixed issue with S63 files only loading the first 10 update files (i.e. no updates over .010).
Fixed issue with BSB charts in map catalogs not displaying.
Fixed export of text in right-to-left character sets (i.e. Hebrew and Arabic) to PDF files.
Fixed issue with font style attributes (like FONT_ANGLE) only applying to the first feature in a file for Shapefiles that only had font-related style attributes.
Fixed issue with cropped export to GMP format losing per-vertex time stamps and fly-through information for any lines that are cropped.
Fixed issue with gaps in OTF terrain layer.

Rendering/Style Changes

Improved visibility of cursor for Measure Tool so that it shows up better on dark backgrounds.
Don’t show font rotation and placement options for features that don’t support those options, like line features.
Updated dialog for naming and saving the current view to have a drop-down list of existing view names to choose from in addition to allowing typing a new name.
Fixed issue with deleted line features disappearing when you zoom in on them far enough that much of the line is offscreen and you have render deleted features enabled.
Fixed issue with small render and selection offset when zoomed in on some reprojected data sets.

Misc. Changes

Updated right-click option to export selected layers from the Control Center to support raster and terrain layers.
Updated the Control Center CALC ATTR dialog (Attribute Calculation Setup) with the ability to calculate new attribute values using spreadsheet-like formulas. The new attribute formulas allow numeric, Boolean and string operations, using standard mathematical notation and predefined functions, which include sophisticated text match, search and replace operations using regular expressions. The new formula language is used in the associated new CALC_ATTR_FORMULA script command, and also in the DEFINE_VAR script command (See Scripting Changes section).
Improved exports using image-optimized palettes for data with more than 256 colors but large areas with the same color.
Added support for embedded generated layers (such as from the Raster Calculator or a gridding operation) over 4GB in size in a workspace file.
Made 64-bit Global Mapper work on 64-bit Windows XP (broken in v16.0.0-v16.0.1).
Add group name to the name of any layers in a layer selection list, such as selecting a layer to move another layer after in the Control Center.
When re-ordering vector layers in the Control Center and your Vector Display Order During Draw setting is set to prefer type over layer order, prompt the user to change this as you typically want the change in layer order to have some visual effect.
Added support for panning the Zoom and Reference map views on the Image Rectification dialog using the Page Up/Down and Arrow keys. These keys work when the cursor is over one of the map views.
Allow use of module licenses, such as the Lidar module, from a USB dongle when the main license is not from a dongle.
Improved the automatic backup of workspaces to save backups when changes are made other than just creating new features, including editing and deleting features.
Add new Histogram tab to the Metadata dialog for elevation grids and Lidar data
Updated Attribute Calculation from Control Center right-click menu (or CALC_ATTR script command) to support numeric operations on formatted degree values or numeric values inside parentheses, braces, or brackets.
Updated Configuration dialog so that resizing it grows the feature type lists on the Area Styles, Line Styles, Point Styles, and Lidar tabs.
Improved display of speed on the Feature Vertices dialog for features with multiple vertices in a single second (i.e. tracklogs with sub-second resolution). Now the speed for the 5 seconds around a point is displayed instead of just the instantaneous speed at the point.
ADVANCED: Added support for a registry key (DWORD key at ‘HKEY_CURRENT_USER\Software\Global Mapper\MaxThreadCount’) to specify the maximum number of background threads/cores to use for operations that support multi-threading. The default value of 0 will use all but one available system thread in most cases.
The Feature Info dialog now shows the index of the feature in the layer in the ‘Map Name’ field.
Fixed error in v16.0.0 saving a workspace with a view shed layer in it.
Fixed issue with right-click in Control Center sometimes keeping extra layers selected.
Fixed issue where the “?” wildcard character was not being recognized as such.
Fixed issue right-clicking on User Created Features layer and exporting to a file from the Overlay Control Center. This option would duplicate the layer.
Fixed crash when displaying GeoCalc dialogs.
Fixed issue with crash when searching Shapefiles with large DBF files in v16.0.0-v16.0.4.
Fixed issue loading workspaces with references to GeoCalc pass-through coordinate transforms.
Fixed issue with copy-paste with both parent areas and islands selected pasting duplicate copies of the selected islands.

Fixed issue with the elevation or color of a clipped layer being shown in the status bar even when you hover over a clipped portion of the layer.
Fixed bug in v16.0.0-v16.0.5 with layers cropped to a polygon becoming a single color when loaded from a workspace which contains the crop.

What's New in Global Mapper v16.0

SDK-Specific Changes

The SDK is now built in Visual Studio 2012. The C runtime library and MFC libraries needed as now those for Visual C++ 11. The older C runtime and MFC are also still needed for some 3rd-party libraries. See the 'what to distribute' files for details.

Updating licensing so that any Lidar module functionality requires an updated license. Please contact sales@bluemarblegeo.com for more information if you need to use functionality that is in the Lidar module in the Global Mapper application. Note this doesn’t affect basic Lidar functionality like loading and rendering Lidar formats and exporting LAS/LAZ files, it is only for functionality like Lidar automatic classification and feature extraction using the scripting functions in the SDK.

Added mUsedDefaultProj to GM_LayerInfo_t so you can tell if the default projection was used for a layer.

Added support for generating contours at just a single height by setting the new GM_ContourParams_t.mSingleLevelOnly to TRUE.

Added new GM_ColorFormat_t32 types for getting 24-bit RGB or BGR in-memory images from GM_DrawLayerListToMemory.

Fix issue with importing/exporting KML/KMZ files in multiple running threads/instances at once. Now the temporary files are stored in separate folders for each instance to avoid collisions.

Significant New Features

Added support for providing a default projection to use when starting the application or unloading everything. If you define a projection in a startup.prj file in either the install folder or the User Settings file list on Help->About, that projection will be automatically selected at application start or when you unload everything.
Dramatically sped up many operations by making use of multiple cores. The following operations are now much faster in most cases:
- Contour Generation
- View Shed Calculation
- Gridding of 3D vector features
- Search by Attributes/Name
- Creation of area features from equal colors/elevation/slopes
- [LIDAR MODULE ONLY] Automatic classification of Lidar ground points (20X as fast or more)
- [LIDAR MODULE ONLY] Initial display of height-above-ground color for Lidar point clouds
Added option to automatically classify building and high vegetation (i.e. tree) points from a raw Lidar point cloud. This is a very powerful option on the Lidar toolbar (and via the LIDAR_CLASSIFY script command) that, combined with the existing (and much-improved) option to automatically classify Lidar ground points, allows automated classification of over 90% of ground, building, and high vegetation points from a raw Lidar point cloud.
Added option to automatically extract building outlines from classified Lidar point clouds. This is a very useful option on the Lidar toolbar that, combined with the automatic classification and manual cleanup tools, can allow very efficient extraction of 3D building outlines from Lidar point clouds.
Added option to automatically extract tree points/areas from classified Lidar point clouds. This is a very useful option on the Lidar toolbar that, combined with the automatic classification and manual cleanup tools, can allow very efficient extraction of tree points (with crown height and width attributes) as well as approximate tree coverage areas from Lidar point clouds.
Added options to filter Lidar points by class/elevation/color/scan-angle/source-ID/etc. when exporting, gridding, and selecting from point clouds.
Added option to plan and record a 3D fly-through as a video file. New toolbar buttons on the 3D dialog allow setting up and recording a high-definition 3D fly-through.
Support rendering textures on 3D polygons in the 3D view. This allows for the creation of photo-realistic 3D model views when loading 3D data that has texture images included. There is a drop-down on the 3D toolbar to select the Skybox background for the 3D display.
Added a Graph and Chart Manager under the Analysis menu to allow creating graphs and charts from loaded data. The following type of operations are supported:
- Bar graph, histogram, line chart, or bar chart from any attribute field in loaded vector layers.
- Histograms for gridded terrain layers (i.e. DEMs)
- You can save the graph to a BMP file and place it on the map as a fixed screen position layer.
- Graph definitions are saved in the workspace file for easy saving and sharing.
Added option to export selected layers with new right-click option in Control Center. This finally lets you easily export just one or more layers without having to disable the others, export, and then re-enable them.
Added built-in streaming online ASTER GDEM v2 worldwide terrain data set at higher resolution (just over 30 meters) and from a much faster/more reliable server than the previous streaming ASTER GDEM v1 data set.
Removed GEM module. All functionality that was present with the GEM add-on module is now part of the base package.
Added new GeoCalc toolbar to access Blue Marble’s Geographic Calculator coordinate transformation library if you have that installed. The new toolbar has buttons to enable/disable GeoCalc projections and settings and also a dedicated button to launch the Geographic Calculator.
Fixed security issue with MAPI.DLL. Secunia Advisory SA 51510/CVE-2013-0727.

LiDAR Module Only Highlights

Added option to automatically classify building and high vegetation (i.e. tree) points from a raw Lidar point cloud. This is a very powerful option on the Lidar toolbar (and via the LIDAR_CLASSIFY script command) that, combined with the existing (and much-improved) option to automatically classify Lidar ground points, allows automated classification of over 90% of ground, building, and high vegetation points from a raw Lidar point cloud.
Added option to automatically extract building outlines from classified Lidar point clouds. This is a very useful option on the Lidar toolbar that, combined with the automatic classification and manual cleanup tools, can allow very efficient extraction of 3D building outlines from Lidar point clouds. This option is available on the Lidar toolbar and in a script via the LIDAR_EXTRACT command.
Added option to automatically extract tree points/areas from classified Lidar point clouds. This is a very useful option on the Lidar toolbar that, combined with the automatic classification and manual cleanup tools, can allow very efficient extraction of tree points (with crown height and width attributes) as well as approximate tree coverage areas from Lidar point clouds. This option is available on the Lidar toolbar and in a script via the LIDAR_EXTRACT command.
Dramatically improved automatic classification of ground points. The following improvements have been made:
- Improved classification to filter out likely buildings and trees before finding nearly certain ground points. This fixes the common issue of the top of flat buildings being classified as ground points. There are parameters controlling this on the ground classify dialog.
- Tremendously sped up automatic classification of ground points. The operation can be 20 times faster or even more on machines with a large number of cores.
- Added option to ground classify dialog to filter the Lidar points that are considered as possible ground. You can manually filter the points by elevation, color, scan angle, etc.
- Allow performing a ground-point automatic classification just on selected Lidar points.
Added option to Lidar LAS/LAZ export to filter the export so that only points that are within a given elevation range, near any one of a list of colors, within a list of allowed classes, within a scan angle range, and/or within a list of point source IDs are exported.
Added option when gridding Lidar point clouds to filter what points are considered in the grid. You can use that to grid only points that are within a given elevation range, near any one of a list of colors, within a list of allowed classes, within a scan angle range, and/or within a list of point source IDs are exported. For example you might use this to quickly create a ground grid from a Lidar point cloud.
Added option to grid Lidar intensity values rather than elevations when doing a bin-based grid of Lidar point clouds. The intensity grid will default to a grayscale rendering, like an aerial image, but can be customized to use any shader. The option is a new Grid Type selection on the grid options dialog. You can also do this from a script by adding GRID_TYPE=INTENSITY to the GENERATE_ELEV_GRID command.
Added option to grid Lidar height above ground values rather than elevations when doing a bin-based grid of Lidar point clouds. The option is a new Grid Type selection on the grid options dialog. You can also do this from a script by adding GRID_TYPE=HEIGHT_ABOVE_GROUND to the GENERATE_ELEV_GRID command.
Enhanced option to filter the selected Lidar points in the Digitizer Tool to also allow filtering the selection by classification, point source ID, and scan angle range.
Greatly improved filling of gaps when doing binned gridding of Lidar point clouds. The filled gaps should now be much smoother and also calculate more quickly.
Sped up display of height-above-ground color for Lidar point clouds on multi-core machines.
Added support for coloring Lidar point clouds by the difference in height between the first and last return of a multiple return pulse. This is useful for visualizing things like potential tree heights or non-penetrable objects like buildings.
Made path profiles through Lidar points in a map catalog show those Lidar points
Made Feature Info dialog and status bar display modifications to elevations from Alter Elevation Values tab of Options dialog for point cloud layer.
Made the elevation legend display with height colors for a ‘height above ground’ rendering of a point cloud.
Fixed coloring of Lidar path profile as height-above-ground if the main map view is not also using the same draw mode.
Fixed coloring of Lidar path profile as height-above-ground if the main map view is not also using the same draw mode.
Added right-click option on main map when the Path Profile Tool is active but nothing is drawn to set the corridor width for a Lidar path profile .
Support automatically classifying building and high vegetation (tree) points using the LIDAR_CLASSIFY script command.
Support automatically extracting building outlines and tree points/outlines from classified Lidar point clouds using the LIDAR_EXTRACT script command.
Support filtering exports to Lidar LAS/LAZ files by point attributes like elevation, scan angle, classification, color, etc. with the EXPORT_VECTOR and GENERATE_ELEV_GRID commands using new parameters LIDAR_FILTER, LIDAR_COLOR_FILTER, LIDAR_COLOR_DIST, LIDAR_SCAN_ANGLE_RANGE, LIDAR_ELEV_RANGE, and LIDAR_SOURCE_ID_LIST.

New Supported Formats

Support Numerous New 3D Model Formats:
- Collada: *.dae
- PLY (Stanford Polygon Library) : *.ply

[LIDAR MODULE ONLY] Added support for coloring Lidar point clouds by the difference in height between the first and last return of a multiple return pulse. This is useful for visualizing things like potential tree heights or non-penetrable objects like buildings.
Sped up the display of point clouds with a very large number of points (i.e. 10’s of millions) of points, particularly when zoomed in on a small section of the point cloud.
[LIDAR MODULE ONLY] Made path profiles through Lidar points in a map catalog show those Lidar points
Added new built-in point type for Railroad ASPRS class 10 (Lidar, Railroad).
Added support for coloring points by the point index in the point cloud. This allows visualizing the spatial arrangement of the points in the source file.
Updated display of min/max Scan Angle on the Statistics dialog for Lidar point clouds to show the min/max values in degrees rather than the raw scaled values.
[LIDAR MODULE ONLY] Made Feature Info dialog and status bar display modifications to elevations from Alter Elevation Values tab of Options dialog for point cloud layer.
[LIDAR MODULE ONLY] Made the elevation legend display with height colors for a ‘height above ground’ rendering of a point cloud.
Updated creation of point clouds from elevation grid cell centers to create the points in the full native units of the layer and not a more precise unit like centimeters.
[LIDAR MODULE ONLY] Fixed coloring of Lidar path profile as height-above-ground if the main map view is not also using the same draw mode.
Fixed bug in v15.1.6-15.2.1 with Lidar classification filter on the Lidar load dialog not being remembered.
Fixed bug in v15.2.0-v15.2.1 with binned gridding of Lidar data sometimes not creating a layer.

3D Viewer Changes

Added option to plan and record a 3D fly-through as a video file. New toolbar buttons on the 3D dialog allow setting up and recording a high-definition 3D fly-through. To create a 3D fly-through, you first define a fly-through path from a line feature. You can define the camera location and direction for every point along the path, preview the fly-through frame-by-frame or as a single stream, and save the results to an AVI video file with different resolution and frame rates.
[LIDAR MODULE ONLY] Fixed coloring of Lidar path profile as height-above-ground if the main map view is not also using the same draw mode.
Fixed bug in v15.1.6-15.2.1 with Lidar classification filter on the Lidar load dialog not being remembered.
Fixed bug in v15.2.0-v15.2.1 with binned gridding of Lidar data sometimes not creating a layer.
Support rendering textures on 3D polygons in the 3D view. This allows for the creation of photo-realistic 3D model views when loading 3D data that has texture images included. There is a drop-down on the 3D toolbar to select the Skybox background for the 3D display.
Added real-time display of main map display cursor location in the 3D view. You can enable display of a vertical line in the 3D view that shows where your cursor is positioned in the main map view as you move it around.
Added support for drawing the current GPS location and recorded track in the 3D viewer. There on options on the 3D View Options dialog to control the display of the GPS icon.
Made 3D points with rotated symbols draw at the appropriate location in space and with the specified rotation relative to the plane of the surface. This allows for things like floating arrows pointing in different directions.
Added option on toolbar to control whether or not the 2D and 3D map views are linked. By default they are linked so updated in either one also updates the other. If you disable the linking then you can separately pan and zoom the 2D and 3D view windows.
Added option to display skybox. Add a realistic background to your 3D views.
Added display of onscreen notifications as 3D viewer settings change. This will show text about changes to the water height, walk mode height, vertical exaggeration, etc. as text in a corner of the 3D window for some period of time (default is 10 seconds). You can configure the display of these notifications on the 3D view options dialog.
Added support for specifying an Altitude mode of Depth Below Sea Level for vector features (either for an entire layer or for individual features). If this is set the elevation for the feature will be treated as a negative value for display in the 3D view.
Fixed 3D zoom with mouse option which was broken in v15.2.0-v15.2.1.

Path Profile/Line of Sight Function Changes

Made crossing 3D lines shown in the path profile view display at the interpolated elevation at the cross point and not the elevation at the start of the intersecting line segment.
[LIDAR MODULE ONLY] Added right-click option on main map when the Path Profile Tool is active but nothing is drawn to set the corridor width for a Lidar path profile .
Fixed bug in v15.2.0 with path profile dynamically drawn line not being correct for long lines.
Fixed problem with areas that the path profile crosses not being displayed if there are no line features loaded.

Analysis Function Changes

Added support for conditional expressions in the Raster Calculator. This allows things like performing different operations on band/elevation values depending on how they relate to other values. For example, you could have a formula like ‘IF ( B1 > B2, B1 - B2, 0 )’. This would cause the resulting value to be B1 - B2 if B1 > B2, and 0 otherwise.
Improved creation of watershed, water rise, and view shed coverage areas to more rarely create self-intersecting (invalid) areas.
Updated creation of view shed coverage areas with a transmission angle to create a 3D area with the height of each vertex being the height of the transmission at the vertex distance. This allows for a nice 3D display of the transmission beam.
Made volume calculations accurate regardless of what projection you are currently using for display. Previously the volume could be inaccurate if using a distorted projection for the location, like Geographic far from the equator.
Improved pile volume calculation by sampling the terrain at more locations around the pile area boundary to form the “base” surface rather than only sampling at the vertex locations. This helps a lot for pile boundaries with only a few vertices and also lowers the effect a single poorly-placed vertex can have.
Improved pile volume calculation when the pile boundary has some vertices outside of the terrain surface. Before that could cause large spikes in volume as those vertices were treated as 0. Now they are just ignored. It is still best to have all vertices on the terrain surface though.
Updated contour generation to create lines mark as absolute height and contour areas with extrusion disabled to improve the default 3D view.
Added better progress reporting to watershed operation and allow cancel when finding flow to/from points, lines, and areas.
When creating Voronoi diagram, extend lines to clip boundary.

Fixed problem with points with elevations of -9999 or below not gridding.
Fixed error about not enough 3D points being available to grid when trying to grid 1 or 2 3D triangle (TIN) features.
Fixed problem with styling for drainage areas created from watershed calculation. They were displaying with a single color rather than random colors in v15.2.

Digitizer Tool Changes

Added option to range ring creation to create radial areas (as opposed to radial lines) so that you can easily create pie wedges at a fixed radius.
Added an option to create a point feature at the centroid/average of a group of selected point features. This is under the Advanced Feature Creation right-click menu when you have more than one point feature selected.

Updated add of coordinate attributes for line and area features to add a BOUNDS attribute with the bounding box.
Updated creation of line features from selected islands/holes in areas to assign the parent area attributes to the new lines and also add an ISLAND=Y attribute.
Updated creation of regular grid of features to all creating point features at the grid cell centers.
Added support for resampling selected line features at a fixed percentage of the length rather than a fixed distance along the line.
When create points from the vertices of selected features, add the feature name as an AREA_NAME or LINE_NAME attribute to the created points.

Projection/Datum Changes

Sped up change of projection for layers covering a large part of the earth on multi-core systems.
Added built-in AMG (Australian Map Grid) projection so the correct projection name could be used for AGD66/AGD84-based projections (rather than MGA).
Improved display of Transverse Mercator-based projections far from the central meridian.
Added built-in Mars MOLA Sphere datum so that newer Mars data can automatically load with the correct ellipsoid model.
Added built-in Batavia (Indonesia) and NAD83 (NSRS2007), NAD83 (NSRS2011), NAD83 (PA11), and NAD83 (MA11) datums and EPSG codes. Note the special NAD83 datums are currently treated as coincident with base NAD83. The new codes are to allow maintaining the correct metadata.
Added built-in Clarke 1866 Ellipsoid and Clarke 1880 Ellipsoid datums to make it easier to position older small scale maps that only specify an ellipsoid but no datum.

Added option to Shapefile export to include the sides and bottom of extruded 3D areas as additional 3D area features in the export.
Improved loading of multi-part 3D areas with Z values. There were problems with things like the sides of buildings being treated as islands/holes in the top.
Added recognition of additional types from OSM XML files as the proper Global Mapper type.
Improved import of building areas from OSM XML files. They should all come in as areas now and also will be marked to extrude and treat heights as relative to ground.
Additional improvements to Wasp .map export to prevent cross-point errors in Wasp.
Added support for specifying what Z value is treated as the no-data (void) value when loading ASCII files with the 3rd coordinate value treated as the Z (elevation) value. This allows no-data values other than the default of -999999.0.
Added option to control whether -useserver or -netecm is used in the command line when exporting MrSID files and using a cartridge license server on the network.
Update MrSID exports to embed the WKT projection string in the SID file header if the projection/datum could not be fully stored in the GeoTIFF tags in the header. This allows for projections to be stored that aren’t fully describable in GeoTIFF tags.
Updated GML import to remove the prefixes from attribute names, like ‘slip:’. All prefixes are removed except for osgb: and gml: if they won’t result in duplicate attribute names.
Fixed problem with toc.xml files for ECRG format files being overwritten by a Global Mapper map catalog when closing the layer.

Added support for using PRJ files for DWGs.
Improved export of imagery from a map catalog (GMC) draped on top of terrain for 3D PDF export. It will now maintain the full resolution of the data in the map catalog.
Made 3D PDFs export XY units as meters to match the vertical units so the elevations aren’t exaggerated due to unit inconsistencies.
Updated KML/KMZ export so that if a KML folder attribute (default of KML_FOLDER) exists but is empty, the feature will be exported at the top level rather than inside a default folder.
Sped up load of large GeoTIFF DEM files that have an .aux.xml file with the valid min/max elevation range.
Fixed handling of attributes for generic ASCII text files when breaking new features on the change in the value in a particular column. Before the first line of attributes from the next feature could be added to a feature. In addition attributes with different values were added as separate attributes rather than combined in one.
Support file versions up to 1155 for CADRG exports when exporting through the user interface. Previously anything over 33 was not allowed.
Loading a workspace with data loaded from a spatial database now automatically selects the database table rather than prompting user.
Automatically decode Equirectangular projections and more Mars datums from PDS format files.
Fixed bug in v15.2.0-v15.2.3 with manual rectification of TIFF files with the File->Rectify Imagery menu command not doing anything.

Fixed bug in v15.2.0-v15.2.1 with alignment of multi-line text labels in PDF export.
Fixed problem with toc.xml files for ECRG format files being overwritten by a Global Mapper map catalog when closing the layer. This was supposed to be fixed in v15.2.0 but wasn’t really fixed until v15.2.4.
Fixed text size issue with opaque backgrounds for PDF export.
Fixed rendering issues with some PDF files, particular that use transparency.
Fixed issue with some layers not being listed for PDF import so you couldn’t turn them off.
Fixed export of vector layers set to use the UTF-8 text encoding to PDF.
Only show a single error message for all invalid areas encountered during 3D PDF export rather than an error message for each invalid area.
Fixed issues loading some XTF files with bad pings.
Make TIFF orientation other than top-left work for elevation GeoTIFF files.
Fixed crash with some high bit-depth Erdas Imagine files with void values.
Fixed issue with the units coming in as US Feet rather than International Feet for ECW files that use a .aux.xml file for specifying the projection when that .aux.xml specifies international feet.
Support automatic decoding of RGF93 datum from ECW files.
Fixed problem with LDEM (Lunar DEM) PDS files coming in as Sinusoidal projection instead of Equirectangular.

Rendering/Style Changes

Sped up the display of data layers with a very large number of features, particularly when zoomed in on the data.
Added option to draw labels with an opaque (filled) background of a custom color rather than always using the current view background color. The new option is on the font selection dialog.
Added option to add just minimum, maximum, and average attributes when using the ‘Init from Values’ button for attribute-based styling for a layer. This allows easily setting up a color range without initializing to all values for a range of numerical attributes.
Further speed-up when rendering raster layers cropped to polygons, particular when cropped to polygons with large numbers of vertices.
Added loaded view shed layers to the map legend when displayed with the color for each listed along with the view shed layer name.
Fixed crash zooming to view in Google Earth in v15.2.0-v15.2.1.
Fixed problem with dialogs not remembering what they were resized to in v15.2.0-v15.2.2.
Fixed problem with option to hide area labels that are not completely contained within the areas in v15.2.4.
Fixed bug with attributes not showing in Quiver Plot dialog opened from Point Styles tab of Options dialog for layer in v15.2.0-v15.2.4.
Fixed issue with elevation legend showing coloring for wrong range when the topmost layer uses a custom layer shader that is also the same as the shared shader.
Fixed issue with custom vector symbols scaled to a fixed height in meters not always drawing.

Misc. Changes

Made the Configuration, Options, and Metadata dialogs be resizable.
Allow canceling a long search on the search dialog.
Support saving a workspace when no data is loaded, allowing the save of just the projection and map layout settings in a workspace.
Added support for forcing a filename passed on the command line (including .gmw) to be run in an existing instance of GM if possible rather than starting a new instance. Just add -existing to the command line. If you load a workspace in an existing instance, you can also add -no_prompt to the command line to indicate that the “unload all” prompt at the beginning is skipped and the workspace should just be loaded on top of the already loaded data.
When calculating attributes using a numeric operation, like addition, subtraction, or division, treat monetary values with a $ at the front of the attribute as numbers.
Added new Tree point type.
Support using a feature display label or layer name for an elevation attribute.
When splitting a layer by attributes and the description of the layer has been customized, make the new layer names use the customized layer name and not the original one.
Fixed modification of elevation units on vector options dialog. This was broken in v15.2.0-v15.2.1.
Fixed odd selection behavior in the Control Center when clicking on the + or - next to a group of layers. Previously any existing selection would be maintained and the new group also selected, rather than the previous selection being reset.
Fixed installation problems on XP 64-bit in v15.2.0-v15.2.1.
Fixed crash stopping GPS tracking when playing back a NMEA log file in real time.
Fixed rare issue with custom settings, like custom shaders or datums, not reading on application start if you start multiple instances at nearly the same time.
Fix error about parsing GMSettings.xml on systems with no internet connection.
Fixed placement of main Global Mapper window when the placement of multiple monitors is changed. In some cases before it could start up off screen.
