Overview
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 -wReferences
