摘要
通过分析研究目前WebGIS存在的不足,介绍了RIA技术的有关情况,并据此提出了基于RIA构建WebGIS的思路。从Flex RIA的体系结构和关键技术进行阐述,给出了基于Flex RIA构建WebGIS系统的设计方案,开发出基于Flex RIA技术的WebGIS数据挖掘系统。增强了系统用户体验并且提升了系统的响应效率,改进了基于传统技术架构的Web GIS页面简单、响应速度慢、交互性差等缺点,具有较好的实用价值。
Through analyzing and researching the scarcity of present WebGIS,RIA technologies are introduced and accordingly proposed to build WebGIS based on the idea. Describes the architecture and key technologies of Flex RIA,gives the design of WebGIS system and develops the data mining system based on Flex RIA.It enhances the user experience and the system respose and improves technical architecture of WebGIS based on traditional page is simple, slow response, interaction of defects and poor, and has good practical value.
