| Abstract: | In this paper,the theories and methods of building existing three-dimension routemodel are introduced. According to the analysis of the theories and methods, the shortcom ings and difficulties are pointed out,and a new method based on micro-computer is presentedwhich includes generating three-dimension terrain modelby means of aerial survey data ormanual survey data in the region where the railway line will be constructed ;This is a methodwhich utilizes cross section data to creste three-dimension railway line model and showsthree-dimension railway line model on terrain by modifying the terrain model. |
