GAO’s Lidar, short for Light Detection and Ranging, is a remote sensing technology that uses laser pulses to measure distances between the sensor and the Earth’s surface. By emitting rapid laser pulses and recording the time it takes for each pulse to return, Lidar systems generate precise, three-dimensional data about the target area. This technology is employed in various fields, including topographic mapping, forestry, and autonomous vehicles. In topographic surveys, Lidar creates detailed elevation models, aiding in terrain analysis and flood risk assessment. For autonomous vehicles, it provides real-time environmental mapping, enhancing navigation and obstacle detection. Lidar’s ability to produce high-resolution, accurate spatial data makes it indispensable for advanced geospatial and engineering applications.  

The Lidar may also be called: Laser Scanning, Laser Radar, Optical Radar, Laser Ranging, and Light Radar.
