Detecting Terrain Stoniness From Airborne Laser Scanning Data †

Detecting Terrain Stoniness From Airborne Laser Scanning Data †

Three methods to estimate the presence of ground surface stones from publicly available Airborne Laser Scanning (ALS) point clouds are presented. The first method approximates the local curvature by local linear multi-scale fitting, and the second method uses Discrete-Differential Gaussian curvature...
