LiDAR
LIDAR (LIght Distance And Ranging, also known as Airborne Laser Swath Mapping or ALSM) is a relatively new technology that employs an airborne scanning laser rangefinder to produce accurate topographic surveys of unparalleled detail. When combined with GIS, LIDAR data allows for detailed mapping of hydrology and analysis of elevation patters for planning and design. The digital output of LIDAR surveying is a Digital Terrain Model (DTM) or Digital Elevation Model (DEM).
