Abstract

Generating and providing the next generation of geological maps for a world needing resources is an ongoing activity. New sensor technologies, improvements in processing algorithms and the means for large scale spatial data distribution are required. The extensive ASTER image archive provides one avenue for providing another geoscience data base source to supplement and help update past published geological mapping. Examples of using ASTER imagery to provide province to continental scale compositional mapping, have been demonstrated in Australia and elsewhere. This study introduces and examines the possibility of applying this approach in East Africa across difficult terrain and boundaries where traditional techniques have been applied by different mapping agencies. The preliminary results show the potential for ASTER mapping but further processing and on site field validation is needed.
