lidar point cloud vs. bare earth DEM

Divided image with tree-covered slope on one side and the treeless, bare earth on the other side revealing landslides

Detailed Description

By processing lidar point clouds to bare earth DEMs, the vegetation is stripped away to reveal past landslides and steep slopes at risk of failure masked by forested canopies. In dense forests, landslides, especially ones in the distant past, may be invisible on aerial images and hard to detect from the ground.
