摘要
针对传统WebGIS在交互性差、响应速度慢、可扩展性不强等缺点,,针对开源WebGIS技术进行研究,分析了基于AJAX和基于Flex的WebGIS的构建机制,阐述了RIA技术及其优势,提出了基于RIA的开源Web-GIS系统框架,对该框架进行具体设计与实现。研究证明,RIA在地理空间数据的发布和共享中将发挥越来越大的作用,地理信息实现网络共享将会越来越简单。
In view of disadvantages of poor interactive,slow response and low scalability in traditional WebGIS application,this paper analyses the problem existed in WebGIS,introduces the Rich Internet Applications,discusses RIA approaches and its advantages,and analyzes the construction mechanism of WebGIS development based on AJAX and Flex.The author believes that with more research on WebGIS based on RIA,RIA will play greater role in sharing geospatial information,and the geospatial information web sharing will become easier.
