Abstract With ERDAS IMAGIVE 8. 4 software，through rectification，digital orthographical maps inlaying，artificial color-composition to Dian-Zang railway by generating DEM and compounding with remote sensing image，the paper generates a three-dimensional geomorphologic image and visible flight film by extracting information of geological engineering disasters and geological structure. The feasibility of newly-built Dian-Zang railway from the viewpoint of geological engineering has been evaluated.
