Abstract
This research presented automatic lineaments extraction method from SPOT satellite imagery for the purpose of landslide risk assessment. The techniques of image enhancement have been used to improve the ability to detect the lineament according to different directions. LINE Module in PCI Geomatica software was used to automatically extract lineaments according to predetermined parameters. The standardization of lineaments, as well as removing “error” lineament have be done by using some algorithms and other verified data. The statistical results demonstrated lineaments obtained by automatically extraction method from satellite images accordance with the direction structure terrrain of the study area.
