The Geographic Information Visualization plays an important role in the study of geological information and geographic information, the two-dimensional plane in GIS makes the spatial features can be converted to raster images and vector maps, and then makes the relevant analysis has a further simplification in processing, in the meantime, the realization of the three-dimensional topography simulation has maked the geographic research even more fast, convenient, accurate and comprehensive. This paper describes the basic steps in the achieving process of the three-dimensional terrain visualization and a number of issues that need attention during the process of the realization.
