groundΒΆ

The ground command is used to segment the input point cloud into ground versus non-ground returns. The output is a point cloud containing only ground returns. The ground command invokes Point Cloud Library‘s ProgressiveMorphologicalFilter.

Note

The ground command is only available when PDAL is linked with PCL.
