| 摘 要： | 利用MapInfo MapX提供的OCX控件和MapX基本控件分析函数,可实现基于MapInfo的城市道路网网络拓扑结构自动生成.先检查原始道路图层线元素拓扑,剪断道路并生成不交叉的道路图层,再创建道路图层拓扑关系并定义其属性特征,最后生成网络拓扑结构提取、数据结构表示、算法复杂性分析等拓扑文件.

| Abstract: | The Automatic production of network Topological Structure for city road network based on MapInfo is realized by using the basic OCX and MapX analytic function provided by of MapInfo MapX. Firstly, the element topological of primitive road layer-line was examined, and the road was cut off and the road layer non-crossing was created. The topological relation of road layer was established and its attribute characteristic was defined, and finally, topological files were built up such as the extracting topological structure of the network, the expressing data structure and analyszing complexity of algorithm etc. |
