Airborne LiDAR (Light Detection and Ranging) can acquire detailed geometric information of topography and objects. In this paper, an automatic method for extraction and reconstruction of buildings with curved roof was investigated using airborne LiDAR data. Based on the distinct topological relationship and characteristics of contour lines, this method firstly clustered and derives the buildings’...
Airborne LiDAR (ALS) data are characterized by involving not only rich spatial but also temporal information. It is possible to extract moving vehicles with motion artifacts from single-pass airborne LiDAR data, based on which the velocity of vehicles can be derived. In this paper, a series of methods for velocity estimation of moving vehicles using airborne LiDAR data is presented and evaluated....
