PDAL Strongest Features
Why is better than LAStools and Whitebox
- Completly GFOSS (BSD permissive Licence)
- C++ API (https://pdal.io/api/index.html)
- Basic Python Bindings (https://pypi.org/project/PDAL)
- Extensibility with Python, PCL and Matlab (https://pdal.io/stages/filters.html#languages)
- Many Readers/Writers (GDAL/OGR, PGPointClound, Entwine, Numpy...)
- Many basic building block glued in pipelines
PDAL Weakest Features
Why is in some cases you still need LAStools and Whitebox
- 1 core only (paralelization via scripting)
- No native GPU acceleration (BTW can be used in python/numpy filters)
Why PDALtools
QGIS Processing integration
-
Backend chaining
- GRASS, SAGA, QGIS Native, GDAL/OGR,...
- LAStools or WhiteBox
- Automatic GUI generation
- Integration if a full featured GIS as QGIS
