基于客户端插件体系结构的RIA WebGIS框架原理和实现

WebGIS与RIA（Rich Internet Applications）技术的结合，可以提高系统的交互性和用户体验。但目前，缺乏一个RIAWebGIS下的简洁高效的应用框架体系结构，以适应GIS系统与越来越复杂的业务系统的集成。在研究WebGIS的技术特点与分析现有RIAWebGIS框架基础上，提出一种面向前端插件体系结构的RIAWebGIS开发框架，并对该框架的模型层次和关键技术进行了剖析，最后将此框架应用于实际应用系统，验证了该框架的高效性和可扩展性。

Principle and Realization of RIA WebGIS Framework Based on Client Side Plug- in Software Architecture

The combination of WebGIS and RIA （ rich internet applications） technique can improve system interactivity and user experience. However,there is a lack of simple and efficient application framework under RIA WebGIS to meet the need of integration of increasingly complex GIS business systems. Based on the study of the characteristics of WebGIS technologies and thee analysis of existing RIA WebGIS framework, this paper puts folward an RIA WebGIS development framework which is front - end plug - in software architecture oriented and analyses its model hierarchy and pivotal technique. Finally, this framework is used in the practical application to verify its efficiency and scalability.
