摘要
多边形拓扑重建是城市地图更新建库工作中关键性的一步,针对MapStar中拓扑重建的存在的问题,笔者采用MapGIS建拓朴,MapStar赋属性两者相结合的一种方法,能快速完成的多边形拓扑关系的重建,提高建库速度,实验证明,采用此方法,在城市地图更新建库工作过程中可提高30%-40%的工作效率。
The polygon topology reconstruction is a key step in urban map database construction and updating, in view of the MapStar topology reconstruction of existing problems, the author using MapGIS to build topology, MapStar to assign attribute combination of a kind of method, can quickly complete polygon topology relation reconstruction, and improve the speed of building library, experiments show that using this method, the city map more new library work process can be increased by 30%-40% of the work efficiency.
