Autometric, Inc. is currently developing a new Geographic Information System (GIS) to be used in the exploitation of multi-source/multi-sensor information. Digital raster imagery data (optical, radar, multispectral, infrared, etc.), weather data, MC&G data (terrain, vegetation, cultural features and transportation features), and text or intelligence information can be interactively overlaid and geographically fused to aid exploitation analysis. This system, called MILGIS, is tailored for military information and applications. This paper describes the architecture of MILGIS and presents a discussion of the role of GIS technology in support of exploitation analysis.
