• Return Number – Select the return number to assign to vegetation points.

3. Building Classification

☑ Enable Building Classification to detect and classify buildings.

• Minimum Elevation – Define the minimum elevation for a point to be considered part of a building.

1. Check "Limit by Radius."

2. Click "Pick by Radius" and select a point in the point cloud to set the starting location.

3. Enter the radius value to define the processing zone.
