IMPORT

The IMPORT command imports a data file for later use. To determine the proper import parameters, one option is to load the file via the interface and save a workspace. The IMPORT command and parameters will be listed in the workspace file. The following parameters are supported by the command.

  • FILENAME - full path to file to load the data from. This can also be the URL (http: or ftp:) for a file on a web site that you want Global Mapper to download and load. You can include wildcards ('*' or '?') in the FILENAME (v16.0.5. or later) to load all files matching a particular mask. In v17.0.4 or later you can provide workspace or script files (.gmw and .gms) via an IMPORT command rather than using EMBED_SCRIPT.

    If there is a file type missing from this list that Global Mapper imports, save a workspace file with the loaded data, and view it in a text editor to see the import parameters. The AUTO value will work with most files

  • PROMPT_IF_TYPE_UNKNOWN - set to NO if you don't want the user to be prompted to select a file type if the type cannot automatically be determined (useful when looping).

  • SOURCE_URL - specified the URL of the file on the server. If the file specified by FILENAME is not found and there is a SOURCE_URL, the file is downloaded from the URL and saved to the FILENAME location.

Shared Import Parameters

These parameters are shared across import and layer options commands to set layer properties.

  • HIDDEN - set to YES to cause this overlay to be hidden from view after it is loaded. The default is to show the overlay.
  • LAYER_DESC - specifies a description to use for the layer when displaying it in the Control Center. This overrides the default description based on the filename or other information within the file.
  • LAYER_GROUP - specifies the name of the group for the layer in the Control Center. To include multiple layers of grouping put the string <sub> in between levels. For example to make a group with 2 levels of nesting, use LAYER_GROUP="Top Level<sub>Next Level".
  • ALLOW_SELECTION - set to NO to disable selection of features from this layer using either the Feature Info or Digitizer Tools.
  • ALLOW_EXPORT - set to NO to disable export from this layer.
  • LOAD_FLAGS - contains flags for any import options that you were prompted for when loading the file, such as if you have a .tif file that you were prompted to select as elevation or raster. Also things like the coverages and tile sets for VPF layers. To see how to set these if you are writing a script, load a file with the settings that you want in the main user interface and then save a workspace, then examine the IMPORT command in the .gmw file for that file and see how the LOAD_FLAGS were set.
  • METADATA_FILENAME - specifies full path and filename of a file to display the contents of on the Metadata dialog for a layer. The file can be any simple displayable text format, including text and XML.
  • METADATA_URL - specifies a URL to a displayable web file (including HTML web page or XML document) to show on the Metadata dialog for a layer.
  • CODE_PAGE- specifies the code page to use when interpreting text from this layer. By default if the file doesn't specify a code page the current system code page will be used. Use the code page number, or the text UTF-8 (number 65001).
  • ALT_MODE (vector only) - altitude mode specifies how the 3D viewer should interpret z-values in the vector features of an layer, relative to terrain. Altitude mode may also be set in an individual feature, in which case it overrides the layer setting. The following values are supported:
    • UNSPECIFIED - Altitude mode is determined by either the setting in the feature, or if unspecified, the setting in the 3D viewer
    • ABSOLUTE - treat z-values as absolute elevations, ignoring any terrain
    • RELATIVE_TO_GROUND - treat z-values as distances above the terrain
    • RELATIVE_TO_SEA_FLOOR - treat z-values as distances above the sea floor (currently implemented as RELATIVE_TO_GROUND)
    • CLAMP_TO_GROUND - ignore z-values, and clamp the feature to the terrain
    • CLAMP_TO_SEA_FLOOR - ignore z-values, and clamp the feature to the sea floor (currently implemented as CLAMP_TO_GROUND)
    • DEPTH - treat z-values as absolute depths, ignoring any terrain
  • ZOOM_DISPLAY - specifies when the map should be displayed and when it should be hidden based on the display zoom scale. This command will be formatted as a name from the list, below followed by 2 numeric paramters. For example, use ZOOM_DISPLAY="SCALE,25000,0" to have a map display only when zoomed in below 1:25000 scale.
    • ALWAYS - always display the map. The numeric parameters are ignored.
    • PERCENT - display the map when the map bounding box is a certain percentage of the screen size. For example, use ZOOM_DISPLAY="PERCENT,0.10,0" to display the map when its bounding box is at least 10% of the screen size.
    • PIXEL_SIZE - display the map when each display pixel is less than some number of meters in size. For example, use PIXEL_SIZE="SCALE,10,0" to display the map when the current display resolution is 10 meters per pixel (or less/higher resolution).
    • SCALE - display the map when the current display is at or below a certain scale. For example, use ZOOM_DISPLAY="SCALE,25000,0" to display the map when the current draw scale is at or below 1:25000.
    • SCALE_RANGE - display the map when the current display is below a range of scale value. For example, use ZOOM_DISPLAY="SCALE_RANGE,25000,100000" to display the map when the current draw scale is between 1:25000 and 1:100000.
  • PROJ - special Projection Specification type of parameter that specifies the projection to use for the file. This will override any projection information stored in the file.
  • PROJ_NAME (DEPRECATED use PROJ instead) - specifies the name of the projection to use for this file (this will override any projection information stored in the file). This name must have been defined with a prior DEFINE_PROJ command.
  • PROJ_FILENAME (DEPRECATED use PROJ instead)- specifies the name of the projection (.prj) file to use for this file (this will override any projection information stored in the file).
  • PROJ_EPSG_CODE (DEPRECATED use PROJ instead) - specifies the numeric EPSG projection code that defines the projection for this file (this will override any projection information stored in the file). For example, use PROJ_EPSG_CODE=26715 to define a UTM zone 15 projection with NAD27 as the datum and meters as the units.
  • PROMPT_IF_PROJ_UNKNOWN - set to NO if you don't want the user to be prompted to select a projection if the projection of the file cannot be automatically determined.
  • USE_DEFAULT_PROJ - specifies that if no projection can be automatically determined for a layer that the default projection selection should be used rather than prompting the user. Use USE_DEFAULT_PROJ=YES to enable. The default projection uses the first valid option from the following, including a check for linear versus angular numeric ranges:
    • Projection of any files loaded from the same folder
    • Last projection user selected on a projection dialog in this session
    • Current view projection
    • Projection from default.prj in global_mapper.exe path
    • Projection from default.prj in User Settings File path
    • Last projection user selected on a projection dialog in previous session of GM
    • Default UTM/15N/NAD83 projection
  • USE_DEFAULT_POS - specifies that if no position data for a raster layer can be automatically determined that a default position should be chosen so that it displays. Use USE_DEFAULT_POS=YES to enable.
  • PICTURE_POS - specifies that the image should be loaded as a 'picture point' that displays the image when you select the point with the Feature Info Tool. The value should contain the X and Y coordinates (in the projection specified for the layer). For example to place the value at 30N 95W with the projection set as PROJ_EPSG_CODE=4326 you can use PICTURE_POS="-95.0,30.0".
  • LOAD_HIDDEN_PDF_LAYERS - for PDF import, specifies that if no layer prompt is provided that hidden layers should be loaded automatically. Use LOAD_HIDDEN_PDF_LAYERS=YES to enable.

Parameters for display and interpretation of elevation values in terrain layers. See also Raster Parameters below for additional shared parameters.

  • ELEV_FIELD - specifies the name of the attribute field to use as the elevation value for the vector features in a file

  • MAX_ELEV (elevation only) - specifies the maximum elevation (meters) to treat as valid when rendering this layer. Any elevations above this value will be treated as invalid and not be drawn or exported.
  • CLAMP_ELEVS (elevation only) - if a MIN_ELEV and /or MAX_ELEV value is specified, setting this to YES will make any valid elevation values outside of the specified range be clamped to the new range value rather than treated as invalid.
  • VOID_ELEV (elevation only) - specifies the elevation (meters) to replace any void areas in the layer with. If not specified, the void areas will be transparent.
  • SHADER_NAME (elevation only) - this sets the name of the shader to use when rendering the gridded elevation data for this layer. Use this to override use of the shared default shader just for this layer. This must be one of the names displayed in the shader drop down in Global Mapper, such as "Atlas Shader" or "Global Shader" or the name of a custom shader.
  • BAND_RANGE - specifies the range of valid values found in a gridded layer. It can optionally also specify how and how to determine what values are no-data values. If not specified, these values will be automatically determined from the data. The format is a comma-delimited list of values like BAND_RANGE="min_valid,max_valid,band_validity_type,check_invalid_float,band_valid_val_1,band_valid_val_2". The _band_valid_val_1_ and _band_valid_val_2_ values are optional and depend on the _band_validity_type_ value. The individual values are:
    • min_valid - minimum valid value for grid cell samples
    • max_valid - maximum valid value for grid cell samples
    • _band_validity_type -_ specifies how to determine if a cell value is valid. The following type names are recognized:

      • LT_MAX - values < _band_valid_val_1_ are valid
      • RANGE_OPEN - values in open range (band_valid_val_1, band_valid_val_2) are valid
      • RANGE_CLOSED - values in closed range [_band_valid_val_1, band_valid_val_2]_ are valid
    • check_invalid_float - value is 1 if data should be checked for raw float samples for infinite values. 0 if is known no values like that exist.
    • band_valid_val_1 - optional value based on _band_validity_type
    • band_valid_val_2_ - optional value based on _band_validity_type

  • FEATHER_BLEND_POLY (raster only) - specifies the name of a previously defined shape from The DEFINE_SHAPE command allows a multi-point shape (like a polygon) to be associated with a name. The shape name can then be used in later commands for things like cropping and feathering to polygonal boundaries. to feather too. You can also use FEATHER_BLEND_POLY=COVERAGE to calculate the polygonal coverage of the layer and feather blend to that automatically. To feather multiple shapes, also include the POLYGON_CROP_USE_EACH=YES parameter.

    • NONE - no contrast adjustment applied (this is the default)
    • PERCENTAGE - apply a percentage contrast adjustment. The CONTRAST_STRETCH_SIZE parameter can be used to override the number of standard deviations from the mean to stretch to.
    • MIN_MAX - apply a min/max contrast stretch, stretching the available range of values in each color band to the full range of 0-255. For imagery which contains both black and white, this will have no affect.
  • CONTRAST_SHARED (raster only) - specifies whether or not the contrast adjustment for this layer will share the adjustment with other contrast-adjusted layers in order to ensure a consistent modification across layers. Use CONTRAST_SHARED=YES to enable contrast sharing.
  • CONTRAST_STRETCH_SIZE (raster only) - specifies the number of standard deviations from the mean to use in a PERCENTAGE contrast adjustment. The default is 2.0.
  • AUTO_CONTRAST (raster only) - DEPRECATED, use CONTRAST_MODE instead - specifies whether to automatically calculate and apply a 2 standard deviation contrast adjustment to the image. Use AUTO_CONTRAST=YES to turn on. Anything else turns it off.
  • COLOR_INTENSITY(DEPRECATED use COLOR_INTENSITY_FULL parameter) (elevation and raster only). - specifies the color intensity to use when adjusting the brightness of pixels in the overlay. Valid values range from 0 to 20, with 0 being completely black, 10 being no alteration, and 20 being completely white. For example, to make an image slightly darker, you could use COLOR_INTENSITY=7.
  • COLOR_INTENSITY_FULL (elevation and raster only) - specifies the color intensity to use when adjusting the brightness of pixels in the overlay. Valid values range from 0 to 512, with 0 being completely white, 256 being no alteration, and 512 being completely black. For example, to make an image slightly darker, you could use COLOR_INTENSITY=300. (NOTE: This parameter replaces the COLOR_INTENSITY parameter).
  • TEXTURE_MAP (raster only) - specifies that this image should be draped over any elevation data loaded before it. Use TEXTURE_MAP=YES to turn on. Anything else turns it off.
  • PALETTE_NAME (palette-based raster only) - specifies the filename of a recognized palette file to override the default colors in this layers palette or a palette previously defined with the DEFINE_PALETTE command. Use this to change the color interpretation of palette indices.
  • TRANSPARENT_COLOR (elevation and raster only) - specifies the color to make transparent when rendering this overlay. The color should be specified as RGB(<red>,<green>,<blue>). For example, to make white the transparent color, use TRANSPARENT_COLOR=RGB(255,255,255). If you do not wish any color to be transparent, do not use this parameter. Optionally, if the image that you are making transparent uses a palette for the colors, you can specify a palette index in the following format: INDEX(<0-based palette index>). For example, to make the second color in the palette transparent, use TRANSPARENT_COLOR=INDEX(1).
  • TRANSPARENT_COLOR_DIST - for layers that have specified a color to make transparent, this parameter allows you to specify how far a color in the layer has to be from the specified TRANSPARENT_COLOR value to be treated as transparent as well. The default value of 0 means that the colors have to exactly match for the pixel to be treated as transparent. Larger values (up to 256) allow larger distances between the layer color and the transparent color. This is useful for lossy formats, like JPEG.
  • COLOR_GRADE (raster only) - specifies the color grading values to use for this layer (as configured on the Color Grade options dialog tab). This should be a comma-delimited list with the saturation value (from 0-1) first, then the input and output range for the red, green, and blue color channels, as follows: COLOR_GRADE=saturation,red_in_start,red_in_end,red_out_start,red_out_end,...,blue_out_end
  • CLIP_COLLAR (raster only) - specifies whether to clip the collar off of the image. The following values are supported for cropping:
    • NONE - no collar cropping is performed.
    • AUTO - automatically remove a USGS DRG-style collar or a 3.75 DOQQ collar
    • LAT_LON - crop the collar to a a specified set of bounds specified in arc degrees in the native datum of the layer. The bounds should be specified using the CLIP_COLLAR_BOUNDS parameter.
    • NATIVE - crop the collar to a specified set of bounds specified in the native projection system and datum of the layer. The bounds should be specified using the CLIP_COLLAR_BOUNDS parameter.
    • PIXELS - crop a given number of pixels off of each side of the layer. The number of pixels to remove from each side should be specified using the CLIP_COLLAR_BOUNDS parameter.
    • SNAP_DEGREES - crop the collar by snapping each edge to a specified degree boundary specified in arc degrees in the native datum of the layer. The bounds should be specified using the CLIP_COLLAR_BOUNDS parameter. For example to crop the west and east edges to a half degree boundary and the north and south edges to a one degree boundary, use the following: CLIP_COLLAR_BOUNDS=0.5,1.0,0.5,1.0.
    • POLY - crop to a polygon provided with the CLIP_COLLAR_POLY parameter.
  • CLIP_COLLAR_BOUNDS (raster only) - specifies the bounds of the collar to be clipped off when the CLIP_COLLAR parameter is enabled. The coordinates should be specified in arc degrees, native layer coordinates, or pixel counts as a comma-delimited list going west,south,east,north. For example, CLIP_COLLAR_BOUNDS=34.25,-109.0,34.375,-108.875.
  • CLIP_COLLAR_POLY (raster only) - specifies the name of the previously defined shape (with the DEFINE_SHAPE command) to crop the layer to when the CLIP_COLLAR=POLY parameter is used. The coordinates in the shape must have been defined in the native projection system of the layer being loaded. Unless you provide CLIP_COLLAR_POLY_SIMPLIFY=NO, the clip polygon will be simplified to 1/10th of a pixel resolution to reduce the size of the crop polygon for faster cropping without noticeably changing the shape.
  • CLIP_COLLAR_POLY_EXCLUDE (raster only) - specifies that the crop to the polygon specified with CLIP_COLLAR_POLY should keep all parts of the layer outside the crop polygon(s) rather than what is inside the polygon(s). Add CLIP_COLLAR_POLY_EXCLUDE=YES to enable this behavior.
  • CLIP_COLLAR_POLY_SIMPLIFY - specifies that the clip polygon will be simplified to 1/10th of a pixel resolution to reduce the size of the crop polygon for faster cropping without noticeably changing the shape. Enabled by default, use CLIP_COLLAR_POLY_SIMPLIFY=NO to disable.
  • CLIP_COLLAR_POLY_PIXEL (raster only) - specifies that the coordinates in the crop polygon from the CLIP_COLLAR_POLY parameter are in pixel relative coordinates for the layer rather than in the native system of the layer. Use this if you need to crop a layer to a particular boundary in known pixel coordinates. The coordinates will convert to native layer coordinates on load.
  • VIDEO_FILENAME - specifies the full path and filename or URL for a video file to associate with the layer. This video can then be displayed for selected point or line features with a video timestamp.
  • LAYER_FLAGS - specifies various options for the layer (like mesh/3D model display options). This is a bit-mask field that can be specified as an integer or hex number (i.e. 0x3). To build the value, simply add each of the numeric options for the flags you want and then store that number (or convert to hex notation - 0xXXX):
    • 1 - Mesh Display - Wireframe Only - If 1 is added to the value, display textured or colored mesh (3D model) features only using a wireframe (i.e. do not fill them).
    • 2 - Mesh Display - No Wireframe on Zoom - If 2 is added to the value, textured/filled mesh (3D model) features will NOT display a wireframe over the color display when zoomed in far enough that the triangles are large.
    • 4 - Mesh Display - Don't Interpolate Textures - If 4 is added to the value, nearest neighbor rather than bilinear interpolation will be used when sampling the texture for a mesh (3D model). This is slightly faster, but will result in pixelated display when zoomed in.
  • USE_LEGACY_IMPORTER - For TYPE=DXF files only. If USE_LEGACY_IMPORTER=YES is specified the DXF file will be loaded using the legacy import method.

The parameters below allow specifying how to create display labels for vector layers.

  • LABEL_FIELD - specifies the name of the attribute field to use as the label attribute for the features in the file. By default the attribute-based labeling will only be applied to those features that don't already have a label, but if the LABEL_FIELD_FORCE_OVERWRITE attribute is set to YES then all features will have their labels replaced. If you want to build the label from multiple attributes, separate them with '>+<' in the file, like LABEL_FIELD='RD_PREFIX>+<RD_NAME>+<RD_SUFFIX'.
  • LABEL_FIELD_SEP - specifies the attribute separator to use when building a label from multiple attributes. This can be any character(s). For example LABEL_FIELD_SEP='-' will insert a dash between each attribute. Use hex codes to add any non-printable characters, such as LABEL_FIELD_SEP='0x20' to add a space.
  • LABEL_CUSTOM_DEF - specifies a custom free-form string describing how to form the display labels for this layer. This can include embedded attribute values as %ATTR_NAME%.
  • LABEL_FIELD_FORCE_OVERWRITE - specifies that the LABEL_FIELD or LABEL_CUSTOM_DEF attribute value should be applied to all feature labels, not just those that don't already have labels. Use LABEL_FIELD_FORCE_OVERWRITE=YES to enable.
  • SHOW_LABELS - specifies whether or not labels are shown for features in this layer, assuming they would be otherwise shown. The default is SHOW_LABELS=YES. Use SHOW_LABELS=NO to disable the display of labels for this layer regardless of other settings.
  • LABEL_PREFIX - specifies the prefix to prepend to attribute-based labels
  • LABEL_SUFFIX - specifies the suffix to append to attribute-based labels
  • LABEL_FORMAT_NUMBERS - specifies whether or not numeric attribute values should automatically have formatting applied to them. This is enabled by default. Use LABEL_FORMAT_NUMBERS=NO to disable numeric formatting and keep numeric values exactly as they are in the attribute list.
  • LABEL_PRECISION - value is an integer indicating the number of decimal digits to use. This applies to numeric labels.
  • LABEL_REMOVE_TRAILING_ZEROS - This removes the trailing zeros to the right of the decimal place in numeric labels. This can be specified by listing the parameter alone, or accepts boolean values.
  • LABEL_USE_SCIENTIFIC_NOTATION - Display the number in scientific notation. This accepts boolean values, or can be called by listing the parameter alone.

The parameters below allow specifying options for working with Lidar data.

  • LIDAR_DRAW_MODE - specifies how points in a Lidar point cloud layer should be drawn. The following values are supported:
    • COLOR - if the points have an associated RGB color, use that. Otherwise color by elevation.
    • ELEV - color by elevation of the point using the current elevation shader.
    • INTENSITY - color as a grayscale image by the intensity
      • LIDAR_INTEN_SHADER - Specify the terrain shader to be used to color intensity value when using the INTENSITY draw mode option. If this parameter is provided with an empty value the terrain shader selected on the main toolbar will be used.
    • CLASS - color by the point classification
    • RETURN - color by the return number
    • HEIGHT_ABOVE_GROUND - color by the height above ground
    • POINT_SOURCE_ID - color by the point source ID
    • BY_LAYER - color the point cloud based on the source layer
      • COLOR - Use this parameter to specify a custom color, format RGB(R,G,B), to use when using the BY_LAYER draw mode option. If not specified, automatic color assignment will be used when coloring by source layer.
    • POINT_INDEX - color by the index of the point in the cloud
    • RETURN_HEIGHT_DELTA - color by the difference in height between first and last return
    • CIR - color as color infrared if NIR band present
    • NDVI - color by calculated NDVI value if NIR band present
    • NDWI - color by calculated NDWI value if NIR band present
    • DENSITY - color by point density
    • WITHHELD - color by withheld flag
    • OVERLAP - color by overlap flag
    • KEY_POINT - color by key point flag
    • SORT_LIDAR - specifies if a Lidar point cloud format should spatially sort the data on load for better performance. This will override any sort settings from the LOAD_FLAGS parameter. The following values are supported
      • AUTO - spatially sorts the point cloud data only if it is determined to be poorly sorted
      • YES - always spatially sort the point cloud data.
      • COLOR - do not spatially sort the point cloud data
  • LIDAR_POINT_SIZE - specifies how large the points in a Lidar point cloud are drawn. The default value of 0 will automatically scale the points to be larger as you zoom in on them. Specify a fixed number to always draw them at a particular size in pixels.
  • LIDAR_DRAW_QUALITY - specifies the quality setting (0-100) for drawing the Lidar point cloud. Larger values draw a larger fraction of the points when zoomed out, but the draw will take longer to complete.
  • LIDAR_FILTER - specifies a comma-separated list of Lidar class numbers to enable or disable for load. Provide a minus sign (-) to remove the type from the filter rather than add it. The filter starts off with nothing in it if you provide a LIDAR_FILTER string, but you can add ALL to enable everything or NONE to clear the filter, then add or remove stuff after that. For example, to specify a class filter with only types 2 and 3 enabled, use LIDAR_FILTER="NONE,2,3". To get one with everything but classes 2 and 3, use LIDAR_FILTER="ALL,-2,-3".
  • LIDAR_RETURN_FILTER - specifies a comma-separated list of Lidar return types to enable or disable for load. Provide a minus sign (-) to remove the type from the filter rather than add it. The filter starts off with loading everything, but you can add ALL to enable everything or NONE to clear the filter, then add or remove stuff after that. For example, to specify a return filter with only unknown and first returns, use LIDAR_RETURN_FILTER="NONE,0,1". To get one with everything but the first return, use LIDAR_RETURN_FILTER="ALL,-1". The numeric values have the following meanings:
    • 0 - Unknown Returns
    • 1 - First Return
    • 2 - Second Return
    • 3 - Last Return
    • 4 - Single Return
    • 5 - First of Many Returns
    • 6 - Second of Many Returns
    • 7 - Third of Many Returns
    • 8 - Last of Many Returns
  • LIDAR_USE_INTEN_FOR_NIR - specifies that we should treat the intensity value Lidar points as the NIR (near infrared) value if the point cloud has RGB colors but no NIR values of its own. Use LIDAR_USE_INTEN_FOR_NIR=YES to enable.

  • LIDAR_INTEN_RANGE - specifies the valid range of intensity values to expect when loading a Lidar point cloud. Provided as LIDAR_INTEN_RANGE="min,max", like LIDAR_INTEN_RANGE="0.0,1.0" if intensities are in range 0-1. If provided, the raw intensity value from the file will be scaled from the specified range to the standard Lidar intensity range of [0,65535].

The parameters below allow defining a series of control points and rectification parameters for setting up a coordinate mapping from pixel space to real-world projection coordinates for the layer.

  • HAS_3D_POINTS - If HAS_3D_POINTS=YES is used, then the control points will have a Z component after each XY value. If 3D control points are provided, they will shift Lidar, 3D vectors or 3D model layers using the best-fit 3D transform.
  • GCP - specifies a single ground control point for use in rectifying a file. The GCP record consists of 5 comma-delimited fields, the control point name, the pixel X and Y coordinates, and the corresponding ground X and Y coordinates. A separate GCP parameter and value should be used for each control point used in the rectification. As an alternative, the GCP_FILENAME parameter (see below) can be used instead.
    When HAS_3D_POINTS is used the expected values are like GCP="name,x_from,y_from,z_from,x_to,y_to,z_to"
  • GCP_FILENAME - specifies the name of a control point file used to rectify the file being imported. the expected format in the file when HAS_3D_POINTS is provided is: x_from,y_from,z_from,x_to,y_to,z_to,name. Note the name is optional.
  • GCP_PROJ_NAME - specifies the name of the projection that the ground control points are provided in. This name must have been defined with a prior DEFINE_PROJ command. Use this if you want to specify control points in a projection other than what you want to define as the native projection for the file. Note that you must also explicitly specify the name projection of the file using either the PROJ, PROJ_NAME, PROJ_EPSG_CODE or PROJ_FILENAME parameters.
  • TRANSFORM_FILENAME - specifies the name of a control point file used to transform the coordinates of the imported file. This is different than the GCP_FILENAME in that the file defines a mapping of world coordinates to a new set of world coordinates rather than pixel coordinates to world coordinates. Each line should be of the format: x_orig,y_orig,x_new_y_new
  • GCP_PROJ_FILENAME - specifies the name of the projection (.prj) file that contains the projection definition for the projection that the ground control points are provided in. Use this if you want to specify control points in a projection other than what you want to define as the native projection for the file. Note that you must also explicitly specify the name projection of the file using either the PROJ, PROJ_NAME, PROJ_EPSG_CODE or PROJ_FILENAME parameters.
  • GCP_PROJ_EPSG_CODE - specifies the EPSG code of the projection that the ground control points are provided in. Use this if you want to specify control points in a projection other than what you want to define as the native projection for the file. Note that you must also explicitly specify the name projection of the file using either the PROJ, PROJ_NAME, PROJ_EPSG_CODE or PROJ_FILENAME parameters.
  • RECTIFY - specifies the rectification method to use for rectifying this file. Valid value are LINEAR, HELMERT, AFFINE, POLYNOMIAL, and TRIANGULATION. If you do not specify a rectification type but do provide at least two ground control points, the best rectification method will automatically be chosen based on the number of control points specified.
  • RECTIFY_4_POINT_POLY_ONLY - specifies that if RECTIFY=POLYNOMIAL is used to specify the rectification method, the polynomial will always be a 1st degree polynomial and won't switch automatically to a 2nd degree polynomial at 6 or more points. By default, the 2nd degree polynomial will automatically be used
