Abstract:

The Mapping, Charting, and Geodesy MCG Division of the Naval Oceanographic and Atmospheric Research Laboratorys Ocean Science Directorate is the primary activity within the U.S. Navy for conducting research and development in direct support of naval MCG requirements. The Mapping Sciences Branch of the MCG Division was tasked to develop the algorithms and software necessary to process data and to produce bathymetry from the multispectral scanner of the Airborne Bathymetric Survey system when it becomes fully functional. The software developed for this system is called the Multispectral Image Depth Analysis System, or MIDAS. The software processes multispectral data in conjunction with laser- or boat-derived soundings to produce high-resolution bathymetric grids. The system is designed to estimate depths in clear, shallow coastal waters down to 20 m. The depth accuracies, derived from the system using boat soundings for control, ranged from 0.3 m to 1.4 m in waters extending to 3 m and 10 m respectively. The horizontal positioning accuracy of the system was in the 25-m range, as determined from a ground survey.
