Abstract : The role of remote sensing in geologic reconnaissance for purposes of tunnel site selection was studied further and a test case was undertaken to evaluate this geological application. Airborne multispectral scanning (MSS) data were obtained in May, 1972, over a region between Spearfish and Rapid City, South Dakota. With major effort directed toward the analysis of these data, the following geologic features were discriminated: (1) exposed rock areas, (2) five separate rock groups, (3) large-scale structures. This discrimination was accomplished by ratioing multispectral channels. Laboratory-type remote sensing data are shown to permit geologic interpretation. These technological advances are the first steps toward airborne lithologic identification. The method has the potential for still finer discrimination and, hence, application to more rock types.
