【摘要】：WebGIS是Internet环境下的一种传输、处理、存储、分析、显示与应用地理空间信息的计算机系统，是Web技术和GIS技术相互融合的产物，将更广泛的用户群体带入到了GIS应用中。传统的WebGIS基于HTML的页面，存在界面效果差、交互功能弱和反应速度慢等缺陷，，以不能满足用户日益增长的使用需求。RIA(Rich Internet Application，富网络应用程序)，作为新式的网络应用程序，其具备良好的表现力与交互性，给WebGIS的发展带来了新的契机，Silverlight是微软推出的非常有前景的RIA插件，跨平台和浏览器，具有丰富的用户体验和强大的功能；REST（Representational State Transfer，表述性状态转移）风格的Web服务因其简洁高效而越来越受到重视，众多的地理信息服务公司陆续推出了基于REST风格的地理空间服务。本文基于以上技术，以Silverlight和ArcGIS Server为平台，详细阐述基于Silverlight的ArcGIS Server开发的技术路线。作为上述开发方法的具体应用，本文开发了基于WebGIS的宁波都市在线服务平台。平台采用ArcGIS Server9.3发布地图服务，Silverlight客户端通过REST API调用ArcGIS Server服务，实现了地图的基本浏览、测量、多窗口联动对比、查询定位等功能，提高了WebGIS的表现力与交互性，降低了开发的难度，缩短了产品周期，具有一定的理论和现实意义。通过案例验证了基于Silverlight技术的WebGIS系统界面美观、用户体验丰富、反应速度灵敏、功能更加强大，相较于传统的WebGIS，其更具优势，而且基于轻量级的REST服务调用使开发过程简单高效，证明了这种开发方式具有很好的应用前景。
[Abstract]:WebGIS is a computer system for transmitting, processing, storing, analyzing, displaying and applying geospatial information in Internet environment. It is the product of Web technology and GIS technology, which brings a wider group of users into GIS applications. The traditional WebGIS page based on HTML has some defects such as poor interface effect, weak interactive function and slow reaction speed, so it can not meet the increasing needs of users. RIA Rich Internet Application is a new type of network application program. With its good performance and interactivity, Silverlight has brought new opportunities to the development of WebGIS. Silverlight is a very promising RIA plug-in from Microsoft, which is cross-platform and browser. Web services with rich user experience and powerful functions are paid more and more attention to for their simplicity and efficiency. Many geographic information service companies have launched geospatial services based on REST style one after another. Based on the above technology, this paper expatiates the technical route of ArcGIS Server development based on Silverlight on the platform of Silverlight and ArcGIS Server. As the specific application of the above development methods, this paper develops Ningbo Metropolitan online Service platform based on WebGIS. The platform uses ArcGIS Server9.3 to publish map service and Silverlight client calls ArcGIS Server service through REST API, realizes the basic functions of map browsing, measuring, multi-window linkage contrast, query and positioning, and improves the performance and interactivity of WebGIS. It reduces the difficulty of development, shortens the product cycle, and has certain theoretical and practical significance. A case study shows that the WebGIS system based on Silverlight technology has the advantages of beautiful interface, rich user experience, sensitive reaction speed and more powerful function, which is superior to the traditional WebGIS system. Furthermore, the development process is simple and efficient based on lightweight REST service invocation, which proves that this development method has a good application prospect.
