基于政务版地图的POI制作方法研究

Method for POI Making Based on Government Map

为了进一步优化政务版地图制作时兴趣点(Point of Interest, POI)的显示效果,提出了一种能应用于生产实践的POI优化制作方法。基于高德地图API接口,先利用Python语言爬取POI点数据,并通过几何与人工校正等工作过程完成了POI有效数据的获取,然后通过POI数据预处理及多种POI抽稀方式完成多级电子地图的抽稀工作。实验证明,抽稀后的POI点分布合理、整洁美观。

To further optimize the display effect of points of interest(POI)in the production of government maps,a POI optimization production framework that can be applied to production practice was proposed.Based on API interface of Amap,the POI point data was first crawled through the Python language,and the acquisition of valid POI data was completed through geometric and manual correction.Then,the thinning work of multi-level electronic maps was accomplished by data preprocessing and three kinds of POI thinning methods.The experiment has proved that the distribution of POI points after thinning is reasonable,clean and beautiful.
