Bookmark or Share- Lidar | NASA EarthdataLidar stands for Light Detection and Ranging. It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges. Lidar is the optical analogue of radar. Lidar differs from radar in its energy source, a laser in the optical part of the electromagnetic spectrum (near IR and green). Lidar is used to measure things such as: range and altitude atmospheric vertical ...
