The objective of the Rapidly Reconfigurable Data Base (RRDB) project is to develop a system which will produce data bases of terrain, geographic features, and object models which can be directly applied for immediate use with a variety of simulators and mission planning tools. The project emphasis is to produce these data bases rapidly enough that they can be used in a quick reaction mode, i.e., they can be turned around in from one to seven days. As envisioned, the RRDB "system" will consist of a dedicated government owned facility with the necessary hardware/software capability to meet the military's requirement for production of simulator/mission planning tool data bases to support quick reaction mission planning/training. The RRDB facility will produce these data bases according to the format specified by Air Force Project 2851, the Standard Simulator Data Base (SSDB). This paper explores the RRDB system concept and demonstrates its function through the use of a hypothetical hostage crisis situation.
