Tactical Operational Scene (TOPSCENE)

Tactical Operational Scene (TOPSCENE) is an operational training system consisting of 3D imagery products and infrastructure. The TOPSCENE battlefield visualization system lets aircrew and battle commanders rehearse their missions before going into combat with timely, realistic, real-world images of the contingency area. TOPSCENE provides rapid, accurate database construction for real-time 3D fly-through. TOPSCENE features include a fully scalable open architecture utilizing all Commercial-Off-The-Shelf components. Source Data includes high-altitude, high-resolution photographic and digital source data are combined and processed by the off-site Database Generation System to develop contingency databases. A two-dimensional (2-D), large-area terrain digital map is constructed, draped over polygonized Digital Terrain Elevation Data and enhanced with 3-D cultural data. 3-D Terrain Imagery enhancements permit changes in visibility, time of day, sensor imagery and graphic overlays. TOPSCENE can produce imagery clear enough to see major and minor roads as well as buildings, vehicles, doors, and windows.

Using satellite imagery, available photographs and terrain data, the TOPSCENE Database Generation System creates seamless 3-D high resolution databases of terrain and cultural features. These databases are stored on hotswap hard drives, 8 mm tape or digital video disks which are then distributed to the deployable units. Units in the field can update target locations based on the latest locally acquired data. Vertical photographs are combined with the terrain data, digitized and computer-constructed into a mosaic-orthogonal map containing large digital gaming areas that cover country-sized areas (tens of thousands of square kilometers). The primary training emphasis is inaccessible areas.
