Abstract This paper has demonstrated the possibility of developing algorithms to extract lineament information from Landsat TMimagery. We made Use of image smoothing. edge tracing. Hough transformation. inverse Hough transformation etc. in automated lineament detection. After Hough transformation, local maxima are selected in the accumulator array and after inverse Hough transformation, the profile analysis for line segment identification and human-machine interactive methods are used. Some of the rules used by geologists in their image interpretation are applied in automated lineament extraction from digital imagery for improving precision.
