Most government and private organizations use helicopters, drones and airplanes for acquiring LiDAR data. Other elements that play a vital role in the data collection and analysis are the photodetector and optics. There are three primary components of a LiDAR instrument - the scanner, laser and GPS receiver. These light pulses - put together with the information collected by the airborne system - generate accurate 3D information about the earth surface and the target object. LiDAR TechnologyĪccording to the American Geoscience Institute, LiDAR uses a pulsed laser to calculate an object’s variable distances from the earth surface. ![]() What is LiDAR technology and how does it work? Here are a few insights about it that are good to know. It was only during the 1980s after the introduction of GPS that it became a popular method for calculating accurate geospatial measurements. Now that its scope has spread across numerous fields, we should know more about LiDAR mapping technology and how it works. ![]() Even though it was first used in the 1960s when laser scanners were mounted to aeroplanes, LiDAR didn’t get the popularity it deserved until twenty years later. ![]() LiDAR, or light detection and ranging, is a popular remote sensing method used for measuring the exact distance of an object on the earth’s surface.
