%X Multispectral false color composite (FCC) images are widely used in interpretation of linear structures, which are directional because of the restriction of tectonic stress field. However, when the satellite image illumination cannot match the directions of linear structures, the structural features are less visible and their interpretations cannot be clearly recognized. Therefore, the paper brings out a new technique based on directional illumination simulating from digital elevation models (DEMs) to enhance multispectral images, which can enhance the structure lineaments by exchanging the traditional illumination model to the optimum illumination perpendicular to the targets, and allow the interpretation of the directional structure lineaments by using certain direction illumination. The paper interprets the fault-related lineaments by remote sensing image in southern segment of Longmen Mountains thrust belt, and the accurate identifi cation of faults is the key to understanding tectonic structure for future work in oil and gas exploration.
