DESCRIPTION

This tutorial describes the generation of building models from LiDAR point clouds with the Laserdata LiS software. The processing chain starts from a classified point cloud, of which all building points are subset. Unique building IDs are assigned to the points by region growing grouping them to objects. Finally LOD models are derived by alpha-shape computation, polygon rectification and height extrusion based on a raster DTM.
