Total bottom bathymetry, producing high-resolution bottom and subbottom data in shallow water, has been accomplished through the integration of fanbeam, sidescan sonar, scanning sonar, and impedance profiling acoustics. The project called HI-MAP (Hydrographic Inland Marine Acoustic Platform) set out in early 1990 to design a multipurpose high-resolution, shallow water survey system. Today, the system is in full operation, simultaneously generating frequencies of 3.5, 33, 200, 500, 650, and 1000 kHz. HI-MAP is able to survey large corridors of a river in one pass, acquiring bottom and subbottom bathymetry right up to water's edge. Included in this article is a discussion of the acquisition technologies used and the new surveying and data processing techniques developed to correlate and “thin” the data. Also presented is a description and the results of the HI-MAP acceptance test performed by the Army Corps of Engineers. |
