LiDAR Technology


LiDAR (Light Detection and Ranging) is an optical remote sensing technology that can measure the distance to other features by illuminating the target with Light. LiDAR technology has been used in airplanes to measure features on Earth's surface, including determining a detailed elevation model. In locations where LiDAR data is available the ground surface elevation contours can be used to prepare both surface and subsurface field drainage patterns.
