Abstract Research purposes: Based on RGIS application project the purposes were to solve key demands of railway Orbit, such as precision, visualization.
Research methods: According to the formula of railway curve and following strictly scientific calculation, this paper made the information of mileage and orientation of railway transformed into the railway orbit spatial information.
Research results: The paper realized the plane figure visualization of curve spatial information using the GIS module of Mapinfo and SuperMap of China and achieved the 3D visualization of curve data in VC using OpenGL.
Research Conclusions: It can save much time for track mapping of railway and has better technical and economic benefit.
