Abstract:

The Bathymetric Data Reduction SubsystemsBDRS represents a new concept in bathymetric data reduction processing. The BDRS is the primary support subsystem to the Bathymetric Information SystemBIS. BIS is one of eight interactive data base systems to be developed under a global control system known as the Source Data Base SystemSODS. SODS will provide users with both centralized access and information manipulation capability to these various information systems, including BIS. Users will have no direct access to BDRS, but they will be able to retrieve information from BIS through SODS. Through the use of various software programs the BDRS accepts digital data input from analog sources and magnetic tape. Output from the system will consist of proof plots, track-line generation, data base access and editing, and quick look capabilities into the database. New developments contained in the system are Voice recognition digitization system which allows the input of sounding data by spoken word digitization of fathograms and the subsequent proof-plot generation using ships log and the digitized soundings and, the ability to geo-section portions of the data base using circular, triangular, or polygonic searches to define user areas of interest.
