Description

LiDAR (Light Detection And Ranging) is a type of remote sensing. It works like radar except with light or laser beams instead. The time it takes for the laser to travel from the data collector (often mounted on a plane or helicopter) to a surface and back is used to calculate the distance to an object. Lidar can be used to provide highly accurate elevation data. The data is collected as points with elevation (x, y, z). These points can be turned into DEMs (Digital Elevation Models).
