Hydrography is the science of measurement and description of the physical features of bodies of water and their littoral land areas. Special emphasis is placed on the elements that affect safe navigation and the publication of such information in a suitable form for use in navigation. Hydrographic surveys determine the configuration of the bottoms of water bodies, especially as it pertains to navigation, including the detection, location, and identification of wrecks and obstructions primarily through the use of side scan sonar and multi-frequency sonar technology.
