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 50 meters, depending on water clarity and sensor specifications. LiDARbatymetria offers several advantages over traditional bathymetric methods, such as sonar. It can cover large areas quickly, is less susceptible to vessel motion artifacts, and can often be deployed from aircraft, enabling efficient data acquisition over extensive coastal zones, rivers, lakes, and estuaries. The resulting data can be used for a variety of applications, including nautical charting, coastal zone management, habitat mapping, infrastructure planning, and flood modeling. The accuracy of LiDARbatymetria is influenced by factors such as water turbidity, the presence of aquatic vegetation, and the angle of the laser beam.
