Methods are developed to apply space based rigorous topographic Mapping techniques in exploitation of commercially available multispectral iMagery (spot) in conjunction with topographic data, dMaterrain data (dted), and geolugical Maps, to do autoMated geologic Map updates, identification of structure lines, faults and other linear features, perform limited mineral classification, and autoMated geologic Mapping. Methods to autoMatically detect parameters that indicate recent disturbances are also investigated.
