富互联网应用程序技术在地理信息系统开发中的应用研究

Research on Rich Internet Application in GIS Development Application

结合富互联网应用程序技术的最新进展,以Adobe公司的Flex技术为例,研究了基于四叉树的地图金字塔数据模型与瓦片双缓存技术、Flex与地理信息服务的三种后台交互技术,以及Flex的组件及其皮肤属性、动画、滤镜和FXG图形格式等各种用户体验技术在GIS开发中的应用。

Taking Flex technique of Adobe Corporation as an example,this paper studies the quad-tree-based map pyramid data model,the tile double buffering technique,the three background interactive technique between Flex and geographic information,and the application of user experience technique in GIS development including the component,skin,animation,filter and FXG graphic format of Flex,based on the latest development of rich internet application technique.
