PDAL Python support allows you to process data with PDAL into Numpy arrays. It supports embedding Python in PDAL pipelines with the readers.numpy and filters.python stages, and it provides a PDAL extension module to control Python interaction with PDAL.
Additionally, you can use it to fetch schema and metadata from PDAL operations.
python plugin is removed from math/pdal and is available at https://pypi.org/project/PDAL/
py-pdal requires cmake, but also setuptools. Having both at the same time makes the mess. So, I add cmake (and ninja) as a dependency. I've already tested other methods, but for the moment it's the only one that works.
