摘要
介绍了基于WebGIS分幅捕捉栅格地图、建立矢量地图的方法和流程,建立了公交站点、景点等兴趣点信息库,实现了道路网存储、拓扑重建和网络索引的数据结构与模型。
The method of obtaining grid maps one by one based on WebGIS arid then making vector maps is introduced; To create better traffic and scenery data, namely point of interest (POI), an algorithm of transforming the KML data to Maplnfo Interchange files is proposed; In the end, the data structure and model of the road network storage, topology rebuilding and net work index is presented.
