Historically, selection of measurements was more common in hydrographic applications while DTM construction was used for engineering surveys, geology, flow modeling, etc. Since c. 2003 –2005, DTMs have become more accepted in hydrographic practice. Satellites are also used to measure bathymetry.
In the development of hydrographic services, shipping organizations played a part, but the major players were the naval powers. Recognizing hydrographic information was a military advantage these naval organizations, usually under the direction of a "Hydrographer," utilized the expertise of naval officers in collecting hydrographic data that was incorporated into the navy's collection.
