摘　　要：导航电子地图具有地图显示、位置查询、路径规划、距离计算、路线引导等功能。随着我国经济的快速发展和城市化进程的加快,城市的道路信息变化日新月异,实现导航电子地图数据的即时、高效、快速的增量式更新是解决导航电子地图发展瓶颈的唯一途径。鉴于此,结合某典型增量更新案例,对导航电子地图数据的增量更新中几何拓扑维护进行了研究,以满足导航技术对数据实时性的需求。Navigation electronic map has the functions of map display,location query,path planning,distance calculation,route guidance and so on.With the rapid development of China's economy and the acceleration of urbanization,the road information of cities is changing rapidly.The only way to solve the bottleneck of the development of navigation electronic map is to achieve real-time,efficient and rapid incremental update of navigation electronic map data.In view of this,combined with a typical incremental update case,the geometric topology maintenance in the incremental update of navigation electronic map data is studied to meet the real-time data requirements of navigation technology.
