【摘要】：基于RIA（富互联网应用程序）技术的WebGIS技术框架以B/S构架模式为基础，既具有易部署、维护的技术特点，又能像基于C/S构架模式的应用系统一样具有良好的客户端体验。基于WebGIS的实时雨水情信息系统，使遥测设备接收到的雨水情数据在WebGIS平台中电子地图相关监测点实时、动态反映并以柱状图、曲线图等直观图形式表现出来，从而辅助工作人员进行正确和及时的决策。本文将Flex技术与ArcGIS Server平台、Java EE架构相结合，讨论了实时雨水情信息系统的设计与实现。论文在分析WebGIS发展现状及在水利中的应用基础上，介绍了Flex、ArcGIS Server、Java EE的基础理论，分析了ArcGIS Viewer for Flex框架，讨论了实时雨水情信息系统的需求分析和设计，并进行技术实现。通过介绍实时雨水情信息系统的设计与实现展示了一种新的WebGIS实现方式，即客户端使用Flex技术，服务器端使用ArcGIS Server平台和Java EE架构结合的技术。系统通过两种开发方式实现，一种是使用Flex语言实现ArcGIS Server服务功能开发，另一种是使用Flex语言实现采用Java EE架构的服务器业务功能开发。两种开发方式的结合充分发挥各自优势，体现了一种新的WebGIS开发思路。
[Abstract]:The WebGIS technology framework based on RIA (Rich Internet Application) technology is based on the B / S architecture pattern. It has the characteristics of easy deployment and maintenance, and has good client experience as the application system based on C / S architecture.The real-time Rain Water information system based on WebGIS makes the actual data of Rain Water received by the telemetry equipment in the WebGIS platform real-time, dynamically reflected and displayed in the form of histogram, graph and other intuitionistic diagrams.To assist the staff to make correct and timely decisions.This paper combines Flex technology with ArcGIS Server platform Java EE architecture, and discusses the design and implementation of real-time Rain Water information system.On the basis of analyzing the development status of WebGIS and its application in water conservancy, this paper introduces the basic theory of ArcGIS Viewer for Flex, discusses the requirement analysis and design of real-time Rain Water information system, and carries on the technical realization.By introducing the design and implementation of the real-time Rain Water information system, this paper presents a new way of WebGIS implementation, that is, the client uses the Flex technology, the server uses the ArcGIS Server platform and the Java EE architecture.The system is implemented in two ways, one is to use Flex language to realize the development of ArcGIS Server service function, the other is to use Flex language to realize the development of server business function based on Java EE architecture.The combination of the two development methods gives full play to their respective advantages and reflects a new way of WebGIS development.
