Abstract

Landsat TM data of six multispectral bands were used to extract the fault information in the southwest region of Zigui basin which is near the Three Gorges bam, located at the eastern section of Daba Mountain tectonic belt. The techniques consist of spectral enhancement and spatial enhancement. Band ratioing methods, Principal component analysis(PCA), decorrelation stretching were applied in this paper. In the end, these methods would be compared and evaluated. The results showed that the fault information extraction method with Landsat TM data performed satisfied.
