LIDAR (Light Detection and Ranging) is a remote sensing technology that uses a laser beam of light to measure the distance from a LIDAR sensor to distant objects. Its operation is similar to how SONAR measures distances underwater using sound pulses.
LIDAR often is used to measure the height of the ground’s surface and the height of features on the ground. In this case, a LIDAR sensor, mounted in a plane, is flown over the area to be imaged. The …
