Lockheed Martin Tactical Defense Systems (LMTDS) has been participating
in the SEDRIS project since July of 1996. LMTDS has supported the SEDRIS
goals in the establishment of an improved simulation/spatial data model,
and a data interchange standard that can be used to pass terrain, feature,
texture, atmosphere, and ocean data between government, contractor, and
commercial applications with minimal data loss. LMTDS's specific SEDRIS
task has been to develop a SEDRIS API for LMTDS' database structure, as
used in the Special Operations Forces Aircrew Training System (SOFATS)
at Hurlburt Field. This includes developing an API to support feature data
stored in ESRI's Arc/Info® file format, and raster elevation data,
image texture, and three-dimensional model data stored in Interchange File
Format (IFF). LMTDS successfully applied the API to process data used in
a recent Synthetic Theater of War - A exercise.
