LiDAR (Light Detection and Ranging) is a specific type of 3D laser scanning technology. It uses pulsed laser light to measure distances to the Earth’s surface, which is particularly useful for large-scale geographical surveys. 3D laser scanning, in a broader sense, encompasses various methods of using laser beams to capture the physical properties of objects or environments. While LiDAR is a subset within 3D laser scanning, used for specific applications, 3D laser scanning refers to a wider range of techniques and uses.
