Airborne LiDAR (Light Detection and Ranging) is a fast, accurate method of obtaining three-dimensional data for creating Digital Surface Models using LiDAR technology. With an integrated camera, RGB images can be supplemented by LiDAR data to provide a comprehensive evaluation of ground information using an active sensor that uses lasers to measure distances to features and the ground.
Airborne LiDAR provides a highly detailed, geo-referenced and accurate point cloud. As well as traditional mapping products, this data can be used to extract valuable information, such as Digital Elevation Models (DEM) and Digital Terrain Models (DTM). Airborne LiDAR typically allows for the collection of multiple pulses, which enables the collection of digital elevation data of both trees as-well as the ground beneath simultaneously.
