| Correlated Virtual Terrain
JTEP has pioneered the use of correlated terrain to enable L-V-C interoperability. In this process, the terrains used by the various L-V-C systems, or federates, are correlated to a maximum extent to support interactions between federates. Additional innovations in terrain development include stitched terrain, i.e., combining two different geographical areas into a single playbox to enable linking L-V-C federates with limited terrain sets (Grafenfels + Camp Roberts = Grafenbob) and to include current areas of interest for operations and mission rehearsal. Also, JTEP has developed geo-specific and micro-geo-specific terrains. Geo-specific terrain uses high-resolution photo imagery overlaid on high-resolution digital terrain to provide a recognizable and realistic view of real terrain in 3D for use in 3D AAR and for use by the V-C UAV. Micro-geo-specific terrain extends this concept to include photo-realistic images from high-resolution photography of buildings, trees, and cultural features (e.g., signs) to provide a realistic 3D terrain in built-up areas.  |
