Abstract:

This U. S. Army Corps of Engineers has an interest in new technology and techniques in hydrographic surveying for more accurate, efficient, and productive surveys. The use of such new systems by contractors can also produce a more accurate and timely service product for the Corps. Such a system, the Hydrographic Inland Marine Acoustic Platform HI-MAP, produced and used by John E. Chance and Associates JECA, was evaluated in test surveys on the Mississippi River. The Ell-MAP effectively integrates many new technologies, such as a phased-array sweep system and differential GPS positioning on board a trailerable twin-hull vessel, to produce a system well-suited to surveys of typical U.S. harbors, rivers, and lakes.
