Abstract: Remote sensing has its application in various fields like geology and mineral exploration, geomorphology and modern geomorphic process modeling, nature mitigation studies, hazard zone mapping, eco system study in hills, plains, riverine, coastal, marine and volcanic landforms, forest and biomass inventory, fishery. Remote sensing plays a vital in various fields. This technique along with the GIS has been to study the geomorphological, hydro geological, land use/land cover, lithological, structural aspects/ features in the parts of Anaimalai, Pollachi and Udumalpet block of TamilNadu. Integrated approach using geographic information system provides cost effective support in resources inventory including land use mapping, comprehensive data base for resources, analytical tools for decision making and impact analysis for plan evaluation. GIS accept large volumes of spatial data derived from a variety of sources and effectively store, retrieve, manipulate, analyze and display all forms of geographically referenced information. Maps and statistical data can be obtained from the spatial integration and analysis of an area using GIS software. In order to assess the natural resource availability and its potentiality in parts of Anaimalai, Pollachi and Udumalpet block, Tamil Nadu, an integrated remote sensing and GIS based study has been conducted by adopting the standard procedures. The groundwater potential zone of any area is depends on geological formations; geomorphologic unit’s recharges characters, topography, and thickness of weathered and fractured zones. In the present study, area was taken to locate groundwater potential zones by integrated different thematic maps, remote sensing and geographic information system techniques. To find out the ground water potential zones, different thematic maps have been prepared and integrated each of them. They are mainly geology, geomorphology, land use / land cover, lineament etc. Groundwater potential zones have been prepared with help of integrating different thematic maps. This study area is finally to get the groundwater potential zones we have to classified few area such as high, moderate and low potential zones.

Keywords: Remote sensing, GIS, lithology, Geomorphology, Hydrology, landforms etc.
