 This library makes heavy use of PDAL (Butler et al. 2024; Butler et al. 2021) for its IO operations. PDAL and the PDAL Python Bindings provide excellent functional support for conducting standard operations on point clouds. Our work to calculate forest structural metrics would have been a lot harder without PDAL.
