+ Harbour multibeam survey In only one day, SURVEX vessel surveys in high resolution most of the harbour and provides datas for volume calculation. Breakwaters can be mapped with 0.10 x 0.10m cells and topography above water line done simultaneously by TOPOMETRYXTM HR 3D scanner laser unit.
+ Coastal bathymetry 1 to 3 Km2 are covered each day. Side scan sonar imagery is also availlable (maximum 25m depth) and ultra-high resolution sub-bottom profiler designed for shallow water environments
+ Canals, lakes and rivers up to 15 km of canal can be covered each day using GPS+GLONASS positioning blended with inertial navigation
