Bathymetric LiDAR Mapping

Bathymetric LiDAR Mapping is a sophisticated remote sensing technique used to accurately measure and map underwater terrain in shallow water environments such as coastal zones, rivers, lakes, estuaries, and reservoirs. The technology operates by emitting laser pulses from an airborne platform, including aircraft, helicopters, or unmanned aerial vehicles (UAVs). It utilizes two different laser wavelengths: an infrared laser and a green laser. The infrared laser reflects from the water surface, enabling precise measurement of the water level, while the green laser penetrates the water column and travels to the seabed. By recording the time taken for the green laser pulse to return after reflecting from the bottom, the system calculates water depth and generates detailed three-dimensional models of underwater topography. Bathymetric LiDAR provides rapid, accurate, and high-resolution data over large areas, making it valuable for coastal management, navigation safety, flood modeling, environmental monitoring, habitat mapping, and hydrographic surveying. Its ability to collect data in difficult-to-access or hazardous areas significantly enhances the efficiency and effectiveness of aquatic terrain mapping.
