Also known as: Light Detection and Ranging

LiDAR (Light Detection and Ranging) measures range by timing laser pulses reflected off surfaces. Drone-mounted LiDAR like the DJI Zenmuse L2 or YellowScan Voyager produces dense 3D point clouds at 240,000-1,200,000 points per second with 2-3 cm absolute accuracy when paired with RTK and an IMU. Unlike photogrammetry, LiDAR penetrates…

LiDAR (Light Detection and Ranging) measures range by timing laser pulses reflected off surfaces. Drone-mounted LiDAR like the DJI Zenmuse L2 or YellowScan Voyager produces dense 3D point clouds at 240,000-1,200,000 points per second with 2-3 cm absolute accuracy when paired with RTK and an IMU. Unlike photogrammetry, LiDAR penetrates vegetation, sees through dust to the bare ground, and works at night or in low-contrast scenes. FI Tech deploys LiDAR for high-precision DTM extraction in Saudi date-palm farms, NEOM mountain corridors, and oil-and-gas pipeline rights-of-way where photogrammetry struggles with featureless desert sand and vegetation occlusion.
