RUNWAY APPROACH ZONE ENCROACHMENT: In aviation, DSMs can determine runway obstructions in the approach zone. Because objects extrude from the Earth, this is particularly useful in these examples: Digital Surface Model (DSM) – Extruding features are tree canopy A DSM captures the natural and built features on the Earth’s surface.Ī DSM is useful in 3D modeling for telecommunications, urban planning and aviation. But height can come from the top of buildings, tree canopy, powerlines, and other features. In the end, LiDAR delivers a massive point cloud with elevation values. Hence, how this system earned its name of Light Detection and Ranging. When the pulse of light bounces off its target and returns to the sensor, it gives the range (a variable distance) to the Earth. In a LiDAR system, pulses of light travel to the ground. What is a Digital Surface Model (DSM)? Airborne Light Detection and Ranging (LiDAR)
