Massive airborne laser altimetry (ALS) point cloud and digital elevation model (DEM) processing library.
The toolset supports change detection of the built-up area and vegetation, tested primarily on the study dataset AHN - Actueel Hoogtebestand Nederland.

The project is continuously built and tested on Windows 10/11 and Ubuntu 20.04/22.04 LTS.
See the Build instructions for a detailed guide.

An interactive visualization of changes in buildings and vegetation for the Dutch AHN point clouds is available at:
