| 摘 要： | 最短路径分析是GIS网络分析的基础，拓扑关系的建立是最短路径分析的关键。由于MapX不支持空间数据的拓扑结构，因此对于MapX二次丌发的用户来说，最短路径分析成为一个难点一为此讨论了基于MapX的路径数据处理、道路自动断链、拓扑关系的建立等一系列问题，并在此基础上实现了最短路径分析，成功地解决了这一问题。

| Abstract: | The building of topologic relationship is the key to analysis of shortest path. For the secondary developers based on MapX, the analysis of shortest path is a difficulty because MapX does not support the topologic relationship of spatial data. This paper discusses a series of questions as to the preprocessing of route data, automatic Cut-line and the building of topologic relationship. Based on those, the analysis of shortest path is accomplished and the problem is resolved successfully. |
