Abstract :
The Benigraph seafloor mapping system is an integrated system for hydrographic surveying, pipeline inspection, etc. The system consept is modular including fish positioning, high frequency scanning sonar, data storage and presentation, and a fish with cable and handling equipment and can be used with any accurate surface positioning system. The Benigraph will measure the bottom topography with a resolution of 5 cm in depth and 20 cm in the horizontal plane under typical operational conditions.
