Feature Overlap Dialog

The Find Overlapping Features tool will search and identify overlapping features with given properties (overlay, type, attribute). Features that overlap in the selected overlays will be identified in the Feature Overlap dialog (below), in the Overlapping feature pairs window.

Click on the features in the window to select them for editing in the workspace. To further narrow the overlapping features search by Feature Type and Attribute Name or Value, fill our the Feature Properties section.  
The following dialog will be displayed when the Find Overlapping Features toolbar button  is clicked:




For example, this tool can search for buildings that have been incorrectly placed over water features. The user may select each overlapping feature pair from the Overlap Tool, and then use the Digitizer to resolve the overlap issue. Enabling the Zoom to selected Features option will pan the workspace view to selected features.

Feature Properties 1 Group

Feature Type– All of the Global Mapper features types present in the selected overlays are listed here. For convenience, area and line features types are listed together, and given the “AREA” and “LINE” prefix respectively. Select the first feature type you would like to process, or “Any” to process all features.

Attribute– Specify an optional attribute value that the first features must have to be processed. This will be empty by default.

Feature Properties 2 Group

Same as Feature Properties 1– Check this box to search for overlapping features with the same type (and optional attribute). For example, you may wish to find building features that overlap.

Feature Type– Feature type of the second feature. For example, to find buildings that overlap rivers, set feature type 1 to building, and feature type 2 to river.

Attribute– Optional attribute of second features.

Overlays to search for overlapping features– This list will include all active overlays (selected in the Overlay Control Center). Select one or more overlays to search.

Overlapping features– This control lists all of the overlapping feature pairs. Click on a list item to select the features on the map. Use the Digitizer tool to modify the features to resolve the overlap issue.

Search for overlapping features– Click to refresh the list of overlapping features above.

Partial Feature Duplicates

To be considered a 'Duplicate Feature' by the Find Duplicate features tool, features must have exactly the same set of vertices. Lines that do not cross count as overlapping (see below) and can be located with the 'Find Overlapping Features' tool. To be considered overlapping features need only have two vertices in common.
