摘　　要：地图服务是WebGIS的重要特征之一。针对地图中点标注重叠的问题,研究了地图服务应用过程中点标注显示的优化方法,通过构建点标注微移集合自动计算重叠的点标注微移参数,实现点标注的优化显示,解决点标注重叠问题。Map service is known to be one of the most important characteristics of WebGIS.This paper aimed at the problem of marking points' overlaps in a map.Based on this problem,it tried to work out an optimization method of marking points' display during the map service apply process.By means of structuring the set of the marking points' tiny moves,it used the set of the marking points' tiny moves to calculate the overlapped parameters of the marking points' tiny moves automatically which in order to realize the optimized display,so that it could solve the problem of the marking points' overlaps.

关 键 词：点标注 微移 重叠
