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.
