Abstract By means of digital image processing techniques of data integration, image fusion, principal component analysis and directional filter with landsat-7 ETM+ image under the image processing platform of ENVI 4.0 software, the authors successfully enhanced the information of faults in the remote sensing survey of fault structures along Motuo highway in Tibet. With technologies of structure analysis based on geological knowledge, information extraction and thematic mapping supported by ArcGIS 8.2 software, faults in Namjagbarwa region were recognized and interpreted completely, and their features and distribution along the highway route were detected. The results have provided enough scientific evidence for selecting the highway route and evaluating engineering geological conditions.
