What is Hydro Mapping?

Airborne Hydromapping is a new technology for the very detailed survey of rivers, lakes and reservoirs. This airborne-operated, water-penetrating laser system is considered as a technical revolution for the comprehensive and simultaneous monitoring of shallow water bodies (depths down to 8 m), and the adjacent foreland with an accuracy of less than 10 cm. In contrast, sonar measurements are traditionally utilized to determine the deeper bathymetry of rivers, deltas, lakes, and reservoirs (depths of 2 m down to more than 100 m). Combining echo sounding and airborne laser scanning data results in a detailed view of the water body and the surrounding foreland.
