Land suitability analysis is a prerequisite for sustainable crop production. Incessant utilization of land and water resources is occurring in many parts of the world partly as a result of land management practices not being suitably matched to the suitability and capability of the land resources. To help address this problem for the part of Parambikulam Aliyar Command Area of Udumalpet taluk, there is dearth information on spatial distribution of present land use types. This paper describes a land suitability evaluation approach based on Remote sensing methodology and Geographical Information Systems (GIS). The Landsat ETM+ images was used to derive thematic maps like, soil type map, soil erosion, soil depth, soil texture and soil slope were derived apart from ETM data, based on the spectral reflectance and NDVI values, a land use and land cover map were prepared. A Land suitability classification map and aerial extent was prepared as per Soil survey and land use organization for sustainable development.
