LiDAR is a remote sensing technology, used to determine ranges (variable distance) by targeting an object with a laser and measuring the time for the reflected light to return to the receiver.

A remote sensing technology, LiDAR is a way for determining ranges (variable distance) by targeting an object with a laser and measuring the time for the reflected light to return to the receiver. LiDAR technology uses the pulse from a laser to collect measurements. The measurements are used to create 3D models and maps of objects and environments. It is an acronym of light detection and ranging or laser imaging, detection, and ranging. Lidar can also be used to make digital 3-D representations of areas on the earth's surface and ocean bottom, due to differences in laser return times, and by varying laser wavelengths. It has terrestrial, airborne, and mobile uses.
