Sankaran Rajendran received the PhD degree in Geology from the Bharathidasan University, India, in 1996. From 2002 to 2010, he was a Assistant Professor with the Department of Earth Sciences, Annamalai University, India. Currently, he is working in the Department of Earth Sciences, Sultan Qaboos University, Oman. His research interests involve mapping mineral and environmental resources of earth using remote sensing and GIS techniques.
Applications of remotely sensed satellite data are wide and unique in mapping of different lithology, economic mineral resources and ore deposits. The ‘Oman exotics’ are the industrial rocks which have economic importance in the Sultanate of Oman. The present study maps the exotics using Landsat ETM and ASTER satellite data and image processing method namely decorrelation stretching and shows the advantages of the sensors to the discrimination of the exotics. The results of study are verified in the field. The samples of exotics collected from the field are measured to study the spectral absorption to map the exotics.
