Abstract

The main objective of this work is to design an automatic image processing tool for lineament mapping from LANDSAT-TM satellite data. In doing so, three procedures are involved: (i) image enhancement using histogram equalization technique; (ii) automatic lineament detection using Canny algorithm; and (iii) three-dimensional (3D) lineament visualization using SRTM data. The study shows that Canny algorithm provides perfect information about lineaments with 3D image visualization which is reconstructed using SRTM. In conclusion, 3D image visualization can provide excellent information about lineament and geological features from remote sensing satellite data.

Key words: LANDSAT TM satellite data, lineament, Canny algorithm, three-dimensional (3D) reconstruction.
