| 摘 要： | 针对现有WebGIS技术只基于页面的模型、存在诸多局限等问题,构建了基于RIA技术的应急地理信息系统(GIS).该系统采用RIA模型将界面分解成小单元模块,这些小单元或组件既可以与用户直接进行交互,又可以与服务器通信,运行时只需更新客户请求的部分,避免了系统频繁生成整个页面.系统运行结果证明,基于RIA技术的应急GIS,具有功能强大的前端处理能力和高度的互操作性能,提高了空间数据的分析与处理能力,改善了用户体验.

| Abstract: | Aiming at the fact that the current WebGIS technology has many limitations such as only based on page model,the emergency GIS was published based on the RIA(rich Internet application) technology.The interface is broken down into small modules by using RIA in this system.These small units and components can be directly with the user interaction,and communicates with Web server,run only when the update request portion,avoids the system frequently generates entire page.The operation results proved that the emergency GIS system based on the RIA technology had a powerful front-end processing capabilities and high cooperation.It also improved the performance of spatial analysis and the user experience. |
