DESCRIPTION

v.in.pdal supports the following PDAL filters:

groud detection with Point Cloud Library (PCL) Progressive Morphological Filter (Zhang 2003) (filters.ground)
filters.height (requires PCL)

v.in.pdal supports the following filters natively:

2D region filter
Z coordinates filter
return filter
class filter

EXAMPLES

Import only XYZ coordinates of points, limit the import to the current computational region and reproject to the Location projection during the import:

v.in.pdal input=points.las output=points -c -r -w
