An endeavour is made in the present study to identify the groundwater potential zones in the Pulang River basin, Cuddapah district based on the Geological and Geo-electrical investigations. The Geomorphological features and lineament patterns are also studied in locating favourable sites for groundwater. The Geoelectrical soundings conducted at hundred locations in the basin area are interprete...

A method for computer extraction of geological lineaments from LANDSAT images is presented. The variance thresholded map of each image is separated into eight gradient direction maps, where basic linear segments are determined each of which is based on the principal eigen vector of a cluster of pixels whose gradient direction is orthogonal to its orientation. A special linking algorithm operate...
