Firstly,an artificial light source image was simulated by digital elevation model DEM; then,an apparent 3D geological map was prepared by the data fusion of the geological map and the artificial light source image. This new type of geological map has not only the complete geological information of the geological map but also the intuitive features of the terrain, with some three-dimensional effect. At the same time, the digital apparent 3D geological map with geo-coding information can be used to determine the geographic coordinates of any position on the map. This map is potentially useful in such aspects of the field work as geological investigation,positioning and mapping,thus having a very high practical value.
