LiDAR (Light Detection and Ranging) is a modern surveying technology. After Post-processing the data acquired by the LiDAR is used to know the precise elevation and geospatial location of the features captured by it. LiDAR is generally of three types Aerial LiDAR, Terrestrial LiDAR, and Mobile LiDAR, For large-scale mapping and data capturing we use Aerial LiDAR mounted on a survey-grade drone.
