LiDAR (Light Detection and Ranging) is a remote sensing technology that measures distances using laser light to generate highly accurate 3D representations of environments. It functions by emitting laser pulses and measuring the time it takes for each pulse to bounce back after hitting an object. This time-of-flight data, when processed, reveals detailed spatial information about the target surface. LiDAR has become a vital tool across numerous industries, offering precision and speed that traditional survey methods cannot match.
