P.L.Keshava Kiran Kumar, K.Raghu Babu, G.Sudarsana Raju, T.Shiva Pratap Abstract Land use Land cover of any area will be determined by the Geomorphology and Geology of that area because these two factors are influential to formulate the natural resources and these natural resources in turn responsible to design the land use patterns. For the present study, parts of YSR District, Andhra Pradesh, India, falling in the Survey of India toposheet No. 57j03 is taken. A detailed geological, geomorphological and land use land cover mapping has been carried out in the said area, by applying visual and digital interpretation of IRS P6 LISS III satellite imagery. Land use land cover pattern in the study area is divided into builtup land, cultivated land, forest land and uncultivated land (waste land). These features follow a general trend of having a set of natural resources around, which occur between the geomorphological features like structural hills, structural valleys, pediplains, residual hills and denudational hills. Lithology of these established areas assessed as shale, dolomite, cherty dolomite, quartzites and granite. Keywords: Land use land cover, LISS III image, Geomorphology, Geology, Natural resources. 1. Introduction Land use land cover pattern of any area is predominantly influenced by the geology and geomorphology of the area. The study area exists within the Proterozoic Cuddapah basin of southern India. The area is tectonically highly disturbed and anthropogenic disturbances also observed in majority of the places. The area contains structural hills, structural valleys, pediment, pediplain, residual hills and denudational hills (Fig. 1). The rock types in the study area are granite gneiss, schist, granitoid, quartzite, dolomite and shale (Fig. 2). Among the geomorphological features settlements and cultivated land exists in between structural hills, residual hills, denudational hills and within structural valleys, pediplains. Whereas the geology in the settlement adopted areas is shale, dolomite, cherty dolomite, limestone, granite and granite gneiss. Most of the geomorphological features favourable for development of habitation in the study area are pediplains and structural valleys and residual hill, even among these, the pediplains are seem to be more favourable for urbanization. Lithologically the builtup land composed of all rock types present in the study area viz, shales, granites, granite gneiss, dolomite and quartzites. Most of the cultivated land in the study area exists within pediplain which is composed of dolomites, granites, granite gneisses and quartzites. This implies that the pediplains made up of dolomites, granites and granite gneisses are more favourable for habitations as well as cultivation (Table – 1). 2. Study area The geographical position of the study area extends from N14 0 15`00`` to N14 0 30`00`` latitude and E78 0 00`00” to E78 0 15`00`longitude, with intended boundary falling in Survey of India toposheet Nos. 57J03. The seasons are experienced in the area are, cold winter season, hot or summer season and wet mansoon season. Major land units in the area can be categorized as agriculture, forest, barren land, settlement and water body. Physiographically the area is characterized by rugged hills with valleys, pediments and the geology being granites, granite gneisses, cherty dolomites, quartzites and shales. 3. Stratigraphy of the Area The stratigraphic succession of the study area with reference to Nagaraja Rao et al. (1987) is as follows International Journal of Multidisciplinary Research and Development 2015; 2(2): 175-180
