SYNBAPS. Volume 1. Data Base Sources and Data Preparation
2006
Van Wyckhouse, Roger J.
The need for digital bathymetric data in profile form suitable for range-dependent acoustic propagation modeling gave rise to the SYNBAPS (synthetic Bathymetric Profiling System) project. Random great-circle bathymetric profiles on a worldwide basis (where data exist) can be rapidly generated up to 10,000 nautical miles. The ability to do range-dependent, single-point depth retrieval and five-degree-square areal contours are further outgrowths of the project. This first report, in a series of two, specifically deals with the techniques of SYNBAPS data base preparation. Those techniques include approach methodology, chart selection criteria, physical construction, annotations, editing, and primary digitization or scanning. A second, unclassified report (NORDA TN-36) deals with the data base's cubic spline structuring and the techniques of retrieval. Computer software documentation for the SYNBAPS retrieval programs are contractor-generated and are tailored to the data base's host computer. Except for minor maintenance, production running and the final dissemination associated with copies of the data base and retrieval software, this project is considered terminated. However, a recommendation for continued data base coverage to include at least the remaining portions of the Indian Ocean, or optimumly, the southern hemisphere, is urged by researchers in earth sciences, acoustic modeling, and satellite radar altimetry.
