摘要
鹰眼地图是GIS导航中不可或缺的功能,通过鹰眼地图可以确定主地图当前视图在整个地图中的位置。基于油田WebGIS开发过程中对鹰眼地图的这一需求,重点对WebGIS中的鹰眼导航功能的实现进行了研究,并阐述了主地图和鹰眼地图协调控制下的WebGIS模型,在此基础上并提出了一种分布式动态分块加载机制。
The eagle-eye map is indispensable function in GIS,through the eagle-eye map people can determine that the main map current view in the entire map position,based on this demand,this article conducts the research to the WebGIS eagle-eye navigation function,it is described a kind of synchronous control model between main map and eagle-eye map,and is proposed a kind of distributed dynamic loading mechanism.
