In petroleum exploration as well as in the search for mineral deposits, the evaluation of satellite data is generally directed more toward the extraction of indirect indicators instead of direct evidence. In the case of hydrocarbon deposits this is due to the fact that natural oil seeps on land are very rare; vegetation anomalies due to gas seepages are disputable. For mineral occurrences close to the surface gossans or similar features producing spectral anomalies provide direct evidence; still, in most instances such obvious indicators are already known. In both cases visual interpretation making use of contextual and ancillary information will frequently provide better results than classification based on mere spectral properties. The integration of additional data sets like geophysical or geochemical data via a GIS are promising tools for the exploration geologist. Several case histories of the production of several types of geological maps prepared by means of remote sensing are presented. The utilization of some of the more sophisticated methods mentioned results in a marked advance in information extraction from remotely sensed data. Examples for three different applications are presented: Regional mapping (Egypt), structural mapping (Bangladesh), and mapping for mineral exploration (Sudan).
