基于GIS的城市路网拓扑关系的自动建立及最短路径分析
Analysis on Automatic Construction of Topological Relation for City Road Network and Its Shortest Route Based on GIS
【摘要】 采用Arc-Node路网数据模型,建立了基于MapInfo的乌鲁木齐市城市道路路网,利用GIS编程技术完成了路网交点的自动连接和错误处理,以及路段的自动断链技术,从而实现了交通路网拓扑结构的自动建立。以乌鲁木齐市路网为例实现了基于GIS(MapInfo)的最短路径搜索,验证了采用该方法建立具有拓扑关系的道路路网的可行性。
【Abstract】 The city road network in Urumqi city was built based on MapInfo with Arc-Node data model of road network.The design of automatic chain scission and error handing about crossover point of road network was completed.Thereby,the automatic construction of topological structure for city road network and the search of the shortest route were achieved based on GIS(MapInfo).The city road network was verified to be practical.
