Contour Extraction in Buildings in Airborne LiDAR Point Clouds Using Multiscale Local Geometric Descriptors and Visual Analytics.

Topographic Light Detection and Ranging (LiDAR) captures geometric information of the topography of a geographical region, often using airborne platforms. The research and practice of analysis of point clouds acquired using LiDAR is more recent in comparison to that of LiDAR imagery. Point clouds are unstructured datasets, where its geometric or structural classification labels the constituent poi...
