中文摘要: 针对矢量道路图层在生成过程中存在的过头、不及以及交叉口分离等典型的不规范情况，提出采用距离最近原则确定与道路交叉口相连接的各道路之间的关系，应用直线段延长法以及直线段替换法等处理方法，将原始道路图层规范化的节点匹配算法。应用该算法，在VB6.0开发环境和MapInfo二次开发控件MapX支持下，实现了原始道路图层中所有道路的正确关联，为路网拓扑结构的正确构建打下良好的基础。实验结果表明，该算法适用于道路拓扑复杂情形。
Abstract:Considering the typical irregularities in vector road map layer, this application is used to determine the relationship among the various connecting roads, extend the straight-line segment, and replace the straight-line segment. The standardization of the original road layer node matching algorithm is presented. Through application of the algorithm presented, the standardization of road map layer of MapInfo is achieved in the VB6.0 development environment with MapX control. The experimental results show that the algorithm can be applied to the topology complexity road.
