【摘要】 随着Web Services技术的飞速发展,诞生了新一代网络地理信息系统技术框架——空间Web服务平台。该框架体现了“服务即是软件,软件即是服务”的全新理念。随着空间Web服务应用的不断扩展,其平台框架也成为GIS软件技术的重要组成部分,并主导着WebGIS发展的主流方向。论文在介绍空间Web服务的概念和特点的基础上,详细阐述了空间Web服务的研究现状,并概括论文的研究内容和意义。着重论述了空间Web服务平台框架ArcGIS Server的基本架构和管理及其开发方法。论文提出并分析了基于ArcGIS Server的Ajax框架组成及其实现机制,同时介绍Ajax技术的基本组成要素及实现原理,并分析了基于Asp.Net Ajax的ArcGIS Server Ajax框架。构建了基于空间Web服务平台的长沙市饮食信息服务系统。系统中采用的Ajax技术使得用户体验得到了大幅度提升。在基于ArcGIS Server设计并开发的长沙市饮食信息服务系统中,分别介绍了系统的背景、系统总体设计、数据库设计和系统的功能实现并分别予以展示。最后,在对全文进行总结的同时,提出目前需要解决的问题和后续研究工作。论文的研究成果在于基于ArcGIS Server提出了一种构建空间Web服务的解决方案并构建了原型系统,从而解决了传统WebGIS所面临的问题,详细解析了ArcGIS Server的Ajax技术框架,并将Ajax技术应用于ArcGIS Server取得了良好的用户体验。更多还原

【Abstract】 Spatial Web Service Platform as a new generation WebGIS framework, has came into existence with the technique of Web Services was developed rapidly. This platform, which integrates service and software as a unique entity inside the framework, is an innovative concept that not only plays a crucial part in the family of GIS software, but also leads WebGIS to satisfy users’ expectation as long as the application of Web Services is continuously extended.This dissertation brings readers a first impression by an instruction of the concept and characteristics of Spatial Web Service .We explained the concept and some characteristics of Spatial Web Service, summarized research status and detailed the aims of our dissertation. Then it followed by the discussion of basic ArcGIS Server structure and the methodology applied in its development. Then an Ajax framework, also its working mechanism, which is based on the Server, is analyzed. We illustrated the ArcGIS Server Ajax framework amply which based on Asp.Net in this part. The latter part we explained the process of constructing the Spatial Web Service for ChangSha Food Service Information System in which the efficiency of service had been dramatically increased according to users.In this dissertation, we devote it to depict the process of development of ChangSha Food Service Information System, including the background, system design, database design and operation of each functional part as a whole. The last, we summarized this dissertation followed by a conclusion that mentioned some subsequent research and a few problems to be solved in future.The outcomes of our research: first, we established a solution for structuring Spatial Web Service based on ArcGIS Server. Secondly, an original system was designed to give answer to problems confronted by traditional WebGIS. Moreover, we illustrated specifically the technique framework of ArcGIS Server and then applied Ajax into it. Feedback from our users has shown that the framework functioned excellently.更多还原
