Abstract
In this paper, a method of selecting point elements in electronic map based on Voronoi diagram is proposed. The retained point elements can better refl ect the weight of their spatial distribution. The POI is gridded in advance, the grid index is established, and the speed of Voronoi graph is improved. The distance limit between adjacent POI is added to ensure that the adjacent POI does not confl ict with each other when displaying name notes, thus improving the display performance of terminal map.
