RS-GIS BASED LITHOLOGICAL MAPPING OF GALI JAGIR AREA, FATEH JANG, DISTRICT ATTOCK, PAKISTAN

Abstract

Remote sensing techniques assist geologists by providing valuable information about geology and minerals of an area to be surveyed, so that geologists spend quality and focused time in the field. To test this approach, a test site in Fatejang of district Attock has been studied using Landsat ETM+ and ASTER satellite data for lithological mapping and mineral exploration. Five different supervised classification techniques namely maximum likelihood, parallelepiped, minimum distance to mean, mahalanobis distance and spectral angle mapper have been performed upon both satellite data images to find out the suitable classification technique for lithological mapping in the study area. Results of these five classification techniques were compared with the geological map produced by Geological Survey of Pakistan.
