摘要
针对城市快速发展过程中,周期性的城市公众网络电子地图更新无法跟上城市变化速度的问题,在研究信息获取、信息分类、地图更新模式等相关理论的基础上,系统构建了开放式、灵活性强的公众网络电子地图应需更新模式,为城市公众网络电子地图的快速更新提供理论和技术支持。
In order to resolve the problem of network electronic map data updating cannot keep up with city development speed, this paper put forward a method of network electronic map data updating on the basis of studying on information acquisition, information classification, map updating mode, and so on. The new data updating method is called ＂Updating According to Demand＂. We hope that the method can provide theory and technology support for the rapid data updating of urban network electronic map.
