Providing quality hydrographic data on dredging, navigation, and flood control projects requires careful planning and evaluation of all phases of the process. Those process considerations include: basic identification of areas to be surveyed and the conditions under which they will be surveyed, use of in-house hired labor or Architect-Engineer (A-E) service contract forces, dredging performance and time constraints, the most appropriate equipment to collect the data, data density requirements, development of a general survey plan and subsequent site specific survey plans, data processing, data presentation, and data archival and retrieval. Other general factors to be considered might include geodetic survey methods, hydrographic survey methods, computer systems design, acceptable vessel modifications, safe vessel operation, and regional knowledge of survey conditions (from U.S. Army Corps of Engineers).
