基于Silverlight技术的水库管理WebGIS研究
|
摘要
Internet的迅速普及和发展为地理信息系统(GIS)提供了新的发展机遇,Web GIS已经成为GIS技术研究的新热点,本文研究的重点是探讨一个综合利用Silverlight技术和WebGIS技术,以实现一个基于Silverlight的水库管理WebGIS系统原型。
本文可分为三个部分,第一部分介绍了水利信息化、地理信息系统的概念及其发展现状和趋势,并阐述了WebGIS的结构、特点、相关的实现技术、工作原理、构造方法以及主要发展趋势及前沿应用。
第二部分讨论了基于Silverlight技术的水库管理WebGIS系统体系结构,分析了系统体系结构的主要模式和技术发展趋势,提出了基于分布式对象技术的五层体系结构设计模式,详尽分析了数据库服务器、地图服务器、中间件、Web服务器和客户端等五个部分的设计内容及其相互关系,并对体系结构中涉及的关键技术进行了研究。
第三部分介绍了基于Silverlight技术的水库管理WebGIS的系统功能模块划分、数据管理和空间数据库的详细设计,实现了一个基于Silverlight技术的水库管理WebGIS系统原型。
Silverlight是RIA Web的主流技术,是形成WebGIS新的发展方向。论文应用基于Silverlight技术的Web GIS模型,以漳泽水库为案例,开发了水库管理信息系统,为水利行业的WebGIS新技术应用做了一点研究和尝试。
Internet's rapid spread and development has provided new opportunities for GIS's development.WebGIS technology has become the new hot spot of GIS technology.The study focus of this paper explores a comprehensive utilization of Silverlight and WebGIS technology,and aims to achieve a prototype of reservoir management WebGIS based on Silverlight.
This paper is divided into three parts.In the first part,it introduces water information technology, GIS's concepts and their development status and trend, and describes WebGIS structure, characteristics, the realization of related technology, working principle, construction method ,main development trends and cutting-edge applications.
The second part discusses reservoir management WebGIS architecture based on Silverlight,the main patterns and trends development of system architecture, offers distributed object technology based on a five-layer architecture and design patterns, analyzes the database server, map server, middleware, Web server and the client part of the design of the five elements and their mutual relations , and studies architecture of the key technologies involved .
The third part introduces WebGIS reservoir management based on Silverlight function module partition, spatial database, data management and detailed design, implementes a reservoir management WebGIS prototype based on Silverlight.
Silverlight is a RIA Web mainstream technology,it forms a new direction WebGIS.This paper uses Silverlight-based application model of Web GIS technology to Zhangze Reservoir as an example, develops the reservoir management information system , and does a little research and experiments for the water industry's WebGIS application of new technologies.
