Aspects of satellite imagery exploration in GIS-based command and control real-time technologies

The tremendous increase in satellite imagery resolution and accuracy has made it reasonable to exploit such imagery in GIS-based command and control, fusing data streams from UAV/UGV and satellite sensors for C4ISR systems. To fuse imagery from satellite and tactical sensors in real time, the authors apply probabilistic analysis, polyquadrically interpolating evidential reasoning about non-numeric tactical factors and superimposing them on Digital Terrain Models and satellite imagery. Doing this in real time for C4ISR requires highly parallel computation, implemented on Video/Imagery Super-Parallel and Supercomputer-Path (VISP) hardware. Another computation, implemented on for purposes of command decision making missions, making use of GIS environments, Dynamic Time Multiplexed Holographic (DTMH) screens, and 3-D projection for precise visualization of accurate GIS-based imagery. This technology incorporates non-numeric real-time information into the command and control processes with simultaneous integrated 3-D views. Theory and experiment both indicate that the methods and algorithms described here are feasible.
