Lidar points selected with the digitizer tool can be edited and classified by selecting the EDIT - Edit Point Feature option. This will bring up the Edit Lidar Point(s) dialog, here Lidar points can be (re)classified, edited and flagged.
Classification of the point(s) can be specified from the dropdown. When multiple lidar points are selected this will display Multiple Lidar Types Selected. Manual classification of points is also available with the Lidar Module toolbar Lidar (Manual Classification).
Specify the Elevation, Intensity or RGB Color of the selected point(s). When multiple points are selected, this value will display for the first point, but will not be updated for the selection unless the value is manually changed.
Flag selected point(s) as Synthetic, Model Key Point, Withheld or Overlap. Like other editing done in Global Mapper, these changes will not be made to the original Lidar file, but will be stored in the workspace, or applied when a new Lidar file is exported.
