How Does LiDAR Remote Sensing Work? Light Detection and Ranging

Transcript

So LiDAR or light detection and ranging uses lasers to measure the elevation of things like the ground forests and even buildings. It's a lot like sonar which uses sound waves to map things, or radar which uses radio waves to map things, but a LiDAR system uses light sent out from a laser. But aren't lasers used for stuff like, I don't know, scanni... Read More
