Landsat TM digital spectral data of Lancang-Jinghong area(Yunnan Province) has been used for the purpose of geological interpretation. To meet this object, different image processing techniques including selected band color composites, principal component analysis and IHS decorrelation stretching are used to improve the discrimination of different lithological and structural features in the area.It was found that IHS decorrelation stretching images obtained from the transformation of false color composite 741(in red, green and blue) provided the best results based on the original data.By combining the characteristics of images produced by different approaches and other canonically transformed images with available geological data and surface observations, the geological interpretation could be done with satisfactory degree of accuracy.
