 Pathways geographic information system began as a set of programs to prepare United States Geographic Survey(USGS) data to a form usble by the MODSIM III simulation system. With the addition of storage management primitives and a garbage collector, it has grown to a suite of over 200 routines.
Pathways comes with a database of the entire world(most is high-detail data of U.S.) and a large library of mapping and analysis functions allowing for coordinate conversions and line-of-sight calculations. Pathways uses PWS high-level language for building custom procedures. More>

 Pathsim simulation system serves the purposes of the analysis community. Simulations can be created anywhere on earth and include weather effects, terrain elevation and ground cover, and a variety of weapon and sensor systems. The desktop environment provides organization of data, simulation scenarios and results. For detailed analyses, a simple “grid computing” multi-processor scheme permits many thousands of simulation runs in a few hours.
A Pathsim scenario includes one or more objects moving across terrain, sensing other objects, communicating with commanders, and possibly shooting at and destroying them. The simulated objects, including tanks, airplanes, boats, artillery, unmanned vehicles and stationary sensors, have physical models for movement velocity and sensing. The system allows for up to 10 sides with varying degrees of animosity, important for Military Operations in Urban Terrain (MOUT). More>

 Comsim models networks of unattended ground sensors used for sensing movement of humans and vehicles. This simulation helps determine optimal sensor densities, network configurations, and communications configurations. The integrated simulation environment uses Geographic Information Systems (GIS), grid multiprocessing, and genetic optimization. More>
