Remove Vegetation
Remove Vegetation tool removes points in vegetation from points classified as ground. It works within a limited area defined by a selected polygon or a fence.
The can be used, for example, to smooth the ground surface after automatic ground classification.
To remove vegetation from ground points:
1. Use CAD tools to draw a polygon or fence around the area for processing. Select the polygon.
2. Select the Remove Vegetation tool.
The Remove Vegetation dialog opens:
3. Define settings.
4. Click on the Test button to see the result of the settings in a preview.
5. Click OK to apply the classification.
