As the defects of traditional research and development on WebGIS,such as poor man-machine interaction and slow response and so on,a solution based on Flex and Representational State Transfer (REST) technologies is introduced to build flood control information management system.The presentation layer of the system is implemented by means of Flex,which can reduce the difficulty of system development and enhance user experience.Some problems of WebGIS application system,such as complicated release of vector map and slow interaction between server side and the client side,is solved by using REST technical framework.The application of Flex and REST provide a new thought for the application and development of WebGIS.%针对传统的WebGIS系统研究开发中存在的人机交互性差、运行速度慢等缺陷,提出了基于Adobe Flex框架和表述性状态传递(Representational State Transfer,REST)的WebGIS系统的解决方案,并应用于防汛信息管理系统的开发中.系统采用Flex实现表示层的呈现,降低了系统的开发难度,增强了系统的用户体验性;使用REST技术框架解决了矢量地图的发布繁琐、服务器端和浏览器端之间响应速度慢的问题,为WebGIS的应用开发提供了新的思路.
