Point cloud data, as a type of representation of 3D surfaces, are usually produced by airborne or on-ground laser scanning, also known as Light Detection and Ranging (LiDAR). The data are often provided as sets of very dense (x, y, z) points or in a more complex, public file binary format called LAS that may include multiple returns as well as intensities. GRASS GIS supports basic and advanced lidar data processing and analysis.
