| Abstract: | 3D terrain visualization technology had been a foucs of study in geographic information systems, digital photogrammetry, virtual reality. During the design of railway power line, through 3D terrain visualization technology, the designers can have a more intuitive terrain awareness and improve efficiency. Based on the digital elevation model （DEM） data, using VC ＋ ＋6.0 and OpenGL as a platform, it was focused on the establishment of 3D Terrain Visualization System and implementation process. |
