In this paper we studied the Honghe fault zone in the view of large scale extent and the relation of the association of Honghe fault and Xiaojiang fault. In our study we put emphasis upon the methodology research about the application of Digital Elevation Model (DEM) and CIS data. By utilizing DEM we perform the slope angle analysis, which gains valuable results. In addition directional filtering is also proved to be effective
