dc.description.abstractSurface illumination in the mountainous terrains is characterized differently on the sun-facing and shadowed portions of the geologic units. This causes misclassification of the litho-units using satellite remotely sensed data. In the present paper, an effort has been made to use Landsat thematic mapper data for the classification of the different litho-units of the Aravalli mountains of Rajasthan State (India) by applying supervised maximum likelihood classifier. The various litho-units of the Aravalli region have been classified considering the sun-facing and shadowed portions of each unit as different classes based on ground truth data. A geological map prepared from the digital image is found to compare closely with the published geological map.en
