Bulldozer, a DTM extraction tool requiring only a DSM as input

demo

Bulldozer is a free scalable open source Digital Terrain Model (DTM) extraction tool developed at CNES.
This software supports both noisy satellite Digital Surface Models (DSM) and high-quality Lidar DSM.

Bulldozer is part of the 3D image processing chain of the CO3D satellite mission.
It's also used in Evoland project.
