GIS applications have been developed that can be used in regional geologic analysis. The techniques can discriminate lithologic boundaries expressed in images that capture morphologic features resulting from the interaction between surface shaping agents and crustal rocks. Study area selected is the Llano Uplift region, central Texas, a highly suitable test site because of (1) the availability of reliable, repeatable ground control; (2) a moderate topography reflecting complex multi-phase deformational periods; and (3) the lack of large scale geologic maps that would allow a unified interpretation of the region. The objectives are (1) the recognition of strain features being the results of deformational processes that affected basement and cover rocks; (2) the development of methodology to perform this recognition involving the integration of multispectral images, space shuttle photography, and geologic ground control in a GIS database. It is demonstrated that it is feasible to undertake regional geologic interpretations utilizing an integrated GIS database.
