Hydrographic Surveying

  • Donald E. Nortrup


Hydrographic surveying is the wet equivalent of topographic surveying. Its objective is to delineate the shape of a portion of the earth’s surface concealed by water. The surface being mapped cannot be observed directly or occupied, so it is necessary to infer topography from depth measurements. Simply, it is the process of deducing underwater topography from numerous discrete observations of depth at positions throughout the survey area. The quality of its product depends on accuracy and density of these observations.
