基于地理信息系统的轨道交通基础地理信息三维可视化

3D Visualization of URT Foundational Geographic Information Based on GIS

随着地理信息系统(GIS)的快速发展,人们对空间数据的需求日益增大,如何让用户对空间数据有更直观更简便的了解,成为GIS发展的一个热点。介绍了基于GIS的三维可视化方法和关键技术。在ArcGIS三维模块ArcScene的基础上,利用组件技术进行二次开发,对轨道交通基础地理信息进行建模与可视化分析,设计和开发出了基于GIS的轨道交通基础地理信息系统,利用AO技术扩展ArcScene功能,实现了轨道交通基础地理信息的三维可视化。

Following the rapid development of GIS, the demands for spatial data are also increasing sharply. How to acquaint the users with spatial data more conveniently has become a hotspot in GIS development. This paper makes a secondary development of ArcGIS for the design of Urban Rail Transit system on the basis of geographic data, then extends ArcScene functions to realize 3D visualization of URT basic geographic data.
