LIDAR

1. LIDAR stands for “light detection and ranging” or “laser imaging, detection, and ranging”.
2. It is a method for determining ranges by targeting a surface with a laser and measuring the time for the reflected light to return to the receiver (time of flight).
3. LIDAR scanning or 3D laser scanning involves scanning multiple directions.
4. LIDAR has terrestrial, airborne, and mobile applications and wide range in surveying, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, etc.,
5. It is used as a key method for distance sensing for autonomous vehicles.
