基于Dotspatial的地图切片的实现

Implement of tiling map based on Dotspatial

文章讨论了基于Google切片技术对专题图进行切片的方法,给出了切片程序的基本流程,切片缓存的组织方式及基于Dotspatial的切片程序的核心代码。基于文章生成的切片库可以很方便地与Google切片叠加,展示具有背景地图的专题图。

In this paper, we discuss the method of tiling thematic map based on google＇s tiling technology and provide the base flow of the tiling program. As an example,we give some core code of the tiling program based on Dotspatial.Based on the tiles library which generated by the method of this paper, it is very simple to overlay base map with thematic maps.
