Hi, I would like to know if it is possible to filter a point cloud into ground and non-ground points. In other words, is there a way to classify the point cloud so that all the points that represent the ground, i.e. the dirt and sand, are separated from the rest of the point cloud?
Here you will find more information about the automatic point cloud classification: How to generate the Point Cloud Classification
It classifies the point cloud in one of the following predefined groups:
Human Made Object
The points that are erroneously assigned to a point group can be moved manually to the correct point group using the Edit Densified Point Cloud option.

I hope it helps
