基于Python的ArcGIS Server地图瓦片定时自动更新方法

摘要

论述了一种基于Python定时自动更新ArcGIS Server地图瓦片的方法,从地图瓦片定时自动更新的基础和地图瓦更新流程2个方面介绍了具体的实现过程.该方法已在“天地图·安徽”项目中予以应用,显著降低了地图瓦片更新的工作难度,对于局部更新在线地图服务具有很强的可操作性.%The map cache technology solved the problem of browsing efficiency about the Internet map. Because of the map cache updating involves many steps, updating a small region, we need a lot of time. This paper discussed a method of the time-updating map tiles using the tools of the ArcGIS Server Python API. From two aspects that the foundation and the steps to the map tile time-updating, it described the specific implementation process. This method had to be applied in the World Map of Anhui Project. It significantly reduced the difficulty of the map tile updating, and was operable for partial updating the online map services.
