Distributed Mission Training (DMT) F-15C Program has been underway to augment existing USAF joint training capabilities. Each DMT F-15C site consists of four full-field-of-view Visual Integrated Display Systems (VIDS's) driven by high-end ESIG-4530GT image generators (IGs). Also parts of each DMT F-15C site are desktop PC-based IGs networked with the ESIGs. The challenge is to achieve visual correlation using IGs and databases (DBs) of such widely differing performance levels and architectures. This paper describes a DB conversion process jointly developed by Boeing, Westar, Evans and Sutherland (E&S), and Terrain Experts. One of several challenges was polygon co-planarity, however, cutting coplanar polygons into the underlying layers by an Automated Database Generation and Reconstruction Tool solved the problem. Excellent degree of correlation, accuracy, and PC-based IG update rates have been achieved for the Eglin, Nellis, Langley, and Southwest Asia databases, indicating a significant potential for cost-saving re-use of existing databases by PC-based image generators.
