| 摘 要： | 为了使"天地图"中大数据量、高密度的POI数据在各显示比例下达到清晰易读的表达效果,本文在考虑POI权重属性的情况下,提出了一种基于四叉树算法进行自动过滤的方法,达到各级比例尺优化显示的效果,并通过实例验证该方法的可行性、稳定性,达到了对POI数据高效过滤和图面表达美观的双重效果。

| Abstract: | In order to achieve the effect that make it more clear in the large amount of data and high-density poi data at each ratio in "Mapworld".This articlepropose a method that based on quadtree algorithm automatic classification filtration with the POI weight attribute through an example to verify the feasibility and stability of the method.This method get the dual effects that canachieve high efficiency filter of POI data and artistic surface appearance. |
