LiDAR
LiDAR (Light Detection and Ranging) is a mapping technology that uses laser beams to create detailed 3D maps of areas. Think of it like a very advanced measuring tool that can scan entire landscapes, buildings, or construction sites from the air or ground. Surveyors and mapping specialists use LiDAR because it's much faster and more accurate than traditional measuring methods. It's similar to radar or sonar, but uses light instead of radio or sound waves. The technology creates "point clouds" - detailed 3D pictures that show exact measurements of everything in an area. This helps companies plan construction projects, monitor mining operations, or study environmental changes.
