LiDARbatymetria
LiDARbatymetria, often shortened to bathymetric LiDAR, is a remote sensing technique used to measure water depth and map underwater features. It combines principles of LiDAR (Light Detection and Ranging) with bathymetric surveying. The system typically employs a laser that emits pulses of light into the water. Some of these pulses are reflected off the water surface, while others penetrate the water and are reflected off the submerged seabed. By precisely measuring the time it takes for these different reflections to return to the sensor, the system can calculate the distance to the water surface and the seabed, thereby determining the water depth.
This technology is particularly effective in shallow to moderately deep clear water, generally up to around
