What is LiDAR?
LiDAR (Light Detection and Ranging) measures distance by timing laser pulses, producing precise 3D point clouds of whatever it sweeps. It is the technology inside terrestrial laser scanners, many drone payloads, and even recent iPhones and iPads.
In practice
In AEC, terrestrial LiDAR documents existing conditions to millimeter accuracy; drone LiDAR maps sites and infrastructure; mobile units scan while walking. Accuracy requirements determine which tier a project needs.
