Mapping of physiographic units and the sediments/soils of an area can give useful information for land use planning. Remote sensing technique plays an important role in the mapping of soil, physiographic units and other land resources. In this present study, Thanjavur district, Tamil Nadu has been choosen to prepare physiographic units and soil maps by using IRS-P6 satellite imagery, (Scale 1:50,000). This study reveals that the mapping of different soil/sediment types and physiographic units can be effectively and the land suitability can be inferred.
