LAND CAPABILITY OF DANDAVATHI RIVER BASIN, SORABA TALUK, SHIMOGA DISTRICT USING REMOTESENSING AND GIS TECHNIQUE
This paper provides a set of technique in the use of remote sensing data in conjunction with GIS technology with the objective of defining the agricultural capability of various land units. Dandavathi river basin, situated in Sorab taluk of Shimoga District, was selected as a test area covering about 620 sq.kms. A set of themes required for this operation was examined and defined. These include slope (gradient), elevation, land use and land cover, terrain and soil type. A digital elevation model (DEM) which provides slope (gradient) and elevation data was generated form existing topographic maps. Terrain and land use and land cover conditions were incorporated using two geocoded Landsat images. In addition, a soil map was transferred to the same geographic co-ordinates. The data input layers were organized thematically. The overlay operation is performed to identify areas where a set of specified conditions occurs together. The resultant map displays the land units according to their inherent characteristics and indicates the capabilities for various types of land utilization.
