| This function requires Global Mapper Professional |
The Manual Classification tool in Global Mapper Pro provides quick methods for manually applying classifications to selected point features. Classifications can be applied directly to currently selected points or continuously as points are selected in the workspace. Commonly used classifications are provided with button shortcuts, and all other classifications, including custom classifications created in the Configuration Menu, can be selected from the drop-down menu.
Find the Manual Classification tool from the Classification dropdown in the Lidar toolbar.
To use the classification buttons found in the Manual Classification tool, select a group of points then click on the button corresponding to the classification you wish to use. Checking the Keep Classifying as Points are Selected box will apply the currently chosen classification to points as they are selected in the workspace.
Points can be selected through any method in Global Mapper, including the Digitizer, Path Profile tool, or selected as the result of an analysis.
The Manual Classification dialog can be docked for ease of use. For more information, see Window Docking.
