Techniques for Underwater Data Acquisition
Underwater data acquisition is performed to provide information about the sea-bottom. The purpose is to depict the relief of the seabed topography including all natural and man-made features. In general, underwater data acquisition is the major part of a so-called hydrographie survey. The result of this kind of topographic survey is then presented on nautical charts, which are the marine equivalent of topographic maps on land. Their design is fundamentally similar, however, they incorporate additional features that are used for navigation, such as navigation hazards and aids for navigation (leading lights from lighthouses, buoys and beacons, etc.).
