LiDAR – February 2017

LiDAR Data

LiDAR data are used extensively for multiple purposes, either in their native format or as derivative products.  LiDAR is an acronym for “Light Detection and Ranging.” Similar to RADAR (Radio Detection and Ranging) which uses radio waves, LiDAR uses light wave pulses to measure distance.

LiDAR is used primarily to measure distance.  When used in airborne mapping (mounted in a plane), LiDAR can measure the topography of the ground.  LiDAR uses a light scanning instrument that emits, and then records, the return of infrared light pulses at a rate of 100,000 to 400,000 times per second.
