WebLidar. Find Data. Lidar 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).

A Complete Guide to LiDAR: Light Detection and Ranging
WebMar 29, 2024 · LiDAR (Light Detection and Ranging) works by emitting laser pulses and measuring the time it takes for the reflected light to return. How LiDAR Works. LiDAR is a sampling tool. What I mean by that is that it sends over 160,000 pulses per second. For every second, each 1-meter pixel gets about 15 pulses.
