Abstract : The paper presents the results of MSS data processing for the specific purpose of geological mapping. The data has been collected over a Precambrain terrainin South India in an area locally known as Chitradurga schist belt. The investigations have been carried out at three levels by collecting field, aerial MSS and satellite MSS data over the same area. The characteristic reflectance patterns of some of the commonly occuring rock types have been determined. The lithological units in general have a limited range of reflectances. The interfering effects of soil, vegetation and moisture content in identifying lithological types on aerial MSS imageries are pointed out. Reflectances measured from aerial MSS data cannot be directly correlated with those measured from satellite MSS data, mainly because of the scale difference of the two imageries and the accompanying constraints.
