SEDRIS: Interoperability and Reuse

A Sample of Projects Using SEDRIS

SEDRIS technology is serving the modeling and simulation (M&S) marketplace today. As SEDRIS technology progresses toward adoption as international information technology standards, many Department of Defense (DoD) and international users are adapting current and future system designs to benefit from SEDRIS' complete and unambiguous representation of the physical environment. SEDRIS has been adopted in the U.S. DoD Joint Technical Architecture, and is specifically cited in the NATO M&S Master Plan. The U.S. Army Program Executive Office for Simulation, Training and Instrumentation (PEO STRI) has established a policy that all environmental data will be delivered in SEDRIS format. Several large simulation developments have also committed to the use of SEDRIS technologies.

The U.S. Joint Simulation System will be using SEDRIS interchange within its federation. The Land Development Agent (the Army Warfighter's Simulation (WARSIM)) is using SEDRIS standard interfaces to improve COTS reuse. This minimizes reliance on proprietary formats and reduces sole source dependency. The cost avoidance has been figured at half to three-quarters of a million dollars. The WARSIM Terrain Data Fusion System is built with SEDRIS capability, as well as the evolving Meteorology/Oceanography import system. Specifically, use of the SEDRIS Spatial Reference Model has yielded another four hundred thousand-dollar savings in direct cost avoidance, risk mitigation, and schedule reduction. Through use in the Terrain Common Data Model, WARSIM has adopted SEDRIS as the simulation's environmental language.

The U.K. Ministry of Defence (MoD) has adopted SEDRIS as core technology in developing a simulation database facility through the Defence Science & Technology Laboratory (DSTL). DSTL has also favorably evaluated SEDRIS use for improved interoperability and environmental representation in networked applications. Additionally, following successful use of SEDRIS in the U.S. Close Combat Tactical Trainer (CCTT) program where several million dollars cost saving has been reported, developers of the U.K. Combined Arms Tactical Trainer (CATT) have adopted SEDRIS as their database interface and interchange mechanism.

Other international use and investigation of SEDRIS technology is successfully progressing within NATO, at the government level in Sweden, France, Singapore, Australia and the Netherlands, and through SEDRIS industry partners in Germany, France and Israel. Technical experts from national standards organizations in the U.K., France, Germany, Japan, Korea, Czech Republic, the Netherlands and the U.S. are also evaluating SEDRIS through their direct participation in the international standards development process.

Through an aggressive testing program, SEDRIS has been used for environment database and information interchange in several applications. These have included the interchange of U.S. Joint Strike Fighter (JSF) Multi-Spectral Database (MSDB) content for simulation-based acquisition; the common language and standard interface for federations designed around the Special Operation Forces Air Crew Training System (SOFACTS); and an Environment Federation implementing former Synthetic Theater of War (STOW) dynamic terrain components.

SEDRIS, and its associated transmittal output, is core technology to a Terrain Scenario Generation and Archiving Project that is developing a World-Wide Terrain Database and related production capabilities. Several source data, model, and integrated low-resolution terrain databases will be completed and stored in SEDRIS Transmittal Format for reuse. SEDRIS technology, coupled with the discovery and ordering capabilities of the Master Environmental Library (MEL), can provide information contents of the Navy Oceanic and Atmospheric Master Library, in addition to products developed using World Meteorological Organization and International Hydrographic Organization formats as SEDRIS transmittals. Space data resources of the National Oceanographic and Atmospheric Administration National Geophysical Data Center can similarly be obtained.

The growing use of SEDRIS technologies will continue to benefit the M&S community and the simulation projects by supporting interoperability through reuse and sharing.
