导航电子地图已经被人们广泛应用,导航终端应用的准确度决定于导航电子地图的数据质量,所以对提高电子地图数据的质检尤为重要。对于导航电子地图,数据的路网质量更是起着决定性作用,对导航电子地图数据路网的质量检查进行了研究,主要包括拓扑捏点处理,拓扑悬挂点处理,道路浮岛检查和道路路网连通性检查4种方法,用以控制数据挂接的正确性及数据的连通性,从而提高了道路路网数据的质量。Navigation electronic maps have been widely used by people. The accuracy of navigation terminal applications depends on the data quality of navigation electronic maps, so it is particularly important to improve the quality inspection of electronic map data. For navigation electronic maps, the quality of the road network of the data plays a decisive role. The quality inspection of the navigation electronic map data road network is studied, which mainly includes topological pinch point processing, topological suspension point processing, road floating island inspection and road network quality inspection. Four methods of network connectivity check are used to control the correctness of data hooking and data connectivity, thus improving the quality of road network data.
