%X A 3D realistic image is a core technique of scientific visualization, computer animation, and virtual reality, and an important technique of spatio temporal GIS. OpenGL is the current international standard of 3D image. This article discussed the implementing method for the representation of terrain realistic image based on OpenGL, such as the digital terrain model mapping, the blend of remote sensing image and terrain data, the blend of thematic information and terrain data, animation, virtual reality, and etc.The mapping methods respective to the DTM format such as TIN, GRID and Contour, the direct and indirect blending methods of remote sensing image and terrain data, and the blending method of thematic information and terrain data based on the 2D transparent texture were presented mainly. Based on aforementioned methods, a flood routing visualization system for Jingjing diversion area was developed and the results fit the anticipant goals well.
