摘要
将计算机 3维模型简化中的LoD技术引入电子地图显示中 ,通过构建Delaunay三角网和Voronoi图 ,提出了一种建立点状要素显示LoD模型的算法 ,基本上解决了电子地图显示时出现的重叠、压盖等现象。
When the capacity of data is very large, the display of vector electronic map will usually overlap and overlay. The definition and the beauty of electronic map are disturbed,and the users are difficult to read maps. This paper introduces the LoD technology of computer 3D scene into the displaying of electronic map, uses Delaunay triangulation and Voronoi diagram, discusses the foundation of the LoD model of point feature independent of data.
