发布时间：2019-03-15 10:01
【摘要】：WebGIS是传统GIS技术和互联网相结合的产物,随着互联网的快速发展,使得WebGIS的应用逐渐成为大众化工具,而且扩展到社会各个领域。 基于XML的SVG,是W3C推荐的网络矢量图形解决方案,具有完全开放的、二维矢量、扩展性强、图形表现力强的特点,使得越来越多的知名软件厂商逐步加大对SVG的研究力度,基于SVG的Web图形应用程序如雨后春笋般的出现,SVG的应用范围也从原先单一的地理信息系统领域向其他领域扩展。 本文分析了WebGIS的研究现状和发展趋势,系统介绍了SVG的概念以及SVG应用技术,对基于.NET的Ajax引擎基本框架进行改进,通过分析用户的需求,设计了一个基于SVG的三层体系结构的数字校园的WebGIS系统。该系统实现客户端和服务端的交互,地理信息数据的一体化管理,也为数字校园的资源利用和统一管理提供了一个高效、便捷的方法。研究表明,该系统价格低,扩展性、兼容性高,只需普通的浏览器即可,真正能够满足企业发布个性化地图服务的需求。 本文的主要完成的工作包括：对传统的WEBGIS技术缺陷进行了分析；对SVG和WEBGIS进行结合的可行性进行了分析和验证；对Ajax引擎的设计进行了改进；利用SVG和改进的Ajax引擎为保险职院设计了数字校园WEBGIS系统,并进行了验证。 本文的创新点在于对基于.NET的Ajax引擎进行了改进,将SVG和WEBGIS进行结合并应用在数字校园中,并利用SVG和改进的Ajax引擎对系统进行了开发,实现了满足数字校园的WEBGIS应用原型系统。利用系统对主要功能的实现进行演示表明了系统具有一定的可靠性和实用性。
[Abstract]:WebGIS is the product of the combination of traditional GIS technology and Internet. With the rapid development of Internet, the application of WebGIS has gradually become a popular tool and extended to every field of society. XML-based SVG, is a network vector graphics solution recommended by W3C. It has the characteristics of completely open, two-dimensional vector, strong expansibility and strong graphics expression, which makes more and more well-known software manufacturers step up their research on SVG. The Web graphics application based on SVG has sprung up, and the application scope of SVG has also expanded from the original single GIS domain to other fields. This paper analyzes the research status and development trend of WebGIS, introduces the concept of SVG and the application technology of SVG systematically, improves the basic framework of Ajax engine based on .NET, and analyzes the needs of users. A digital campus WebGIS system based on SVG is designed. The system realizes the interaction between client and server and the integrated management of geographic information data. It also provides an efficient and convenient method for the resource utilization and unified management of digital campus. The research shows that the system has the advantages of low price, expansibility and high compatibility. It only needs a common browser, and can really meet the needs of enterprise to publish personalized map service. The main work completed in this paper includes: analyzing the defects of traditional WEBGIS technology, analyzing and verifying the feasibility of combining SVG and WEBGIS, improving the design of Ajax engine, analyzing and verifying the feasibility of combining SVG and WEBGIS, and improving the design of Ajax engine. A digital campus WEBGIS system for insurance vocational college is designed by using SVG and improved Ajax engine, and verified. The innovation of this paper is to improve the. Net-based Ajax engine, combine SVG and WEBGIS and apply it in digital campus, and develop the system by using SVG and improved Ajax engine. The WEBGIS application prototype system which satisfies the digital campus is implemented. Using the system to demonstrate the realization of the main functions shows that the system has a certain reliability and practicability.
