摘　　要：以三维GIS为技术支持,结合铁路线路设计理论,采集线路相关CAD设计数据,研究了CAD软件、GIS软件、Sketch Up软件联合建立地形模型和线路模型的方法;将模型转换为Multipatch格式数据,应用ArcEngine开发平台,最终建立三维铁路信息系统。A method of terrain model and line model was established supported by 3D GIS technology,combined with the railway line design theory,acquisition circuit CAD design data of CAD software,GIS software and Sketch Up software jointly; and eventually the3 D railway information system was established under model transformation to Multipatch data format,using ArcEngine development platform.
