【摘要】：随着计算机技术、Internet、GIS的发展,以及二维GIS不能真实反映现实世界的现状,三维GIS得到了迅速的发展。Silverligh、Flash、OpenGL等技术的出现为人们在网页上实现三维WebGIS提供了技术可能。本文通过研究多种技术手法：Silverligh、SOE、ArcSDE和Multipatch,实现了一个基于市政管理的三维WebGIS。 通过实现本文的三维WebGIS系统,产生了以下的研究成果。 第一,通过对Silverlight技术的研究,建立了用Silverlight技术实现的WebGIS的客户端,用Silverlight技术实现的WebGIS,具有诸多优点,界面美观、操作流畅、响应效果好、支持矢量数据的显示编辑,并且解决了胖服务端瘦客户端的问题,解放了带宽。 第二,通过对Multipatch数据的研究,建立了用Multipatch数据表达的三维数据模型,逼真的为WebGIS提供了真三维的数据,真实地反映了现实世界。 第三,通过对ArcSDE的研究,建立了通过ArcSDE连接Oracle数据库的方式,通过ArcSDE的连接,可以实现对多种数据库的兼容支持,也能实现在关系数据库中对大数据量空间数据的方便管理,这对于构建分布式数据源、B/S结构的三维WebGIS具有重要的意义。 第四：通过对SOE (Server Object Extension)的研究,建立发布了对Multipatch数据服务的网络发布,并通过这个服务,可以访问Multipatch数据,解决了在浏览器上旱现三维模型的关键问题。
[Abstract]:With the development of computer technology and Internet,GIS, and the fact that 2D GIS can not reflect the reality of the real world, 3D GIS has been developed rapidly. The appearance of Silverligh,Flash,OpenGL and other technologies provides the possibility for people to realize 3D WebGIS on web pages. In this paper, a 3D WebGIS. based on municipal management is realized by studying various techniques: Silverligh,SOE,ArcSDE and Multipatch,. Through the implementation of the three-dimensional WebGIS system, the following research results have been produced. First, through the research of Silverlight technology, the client of WebGIS realized by Silverlight technology is established. The WebGIS, realized by Silverlight technology has many advantages, such as beautiful interface, smooth operation, good response effect, and supports vector data display and edit. And solved the fat service end thin client problem, freed the bandwidth. Secondly, through the study of Multipatch data, a 3D data model expressed by Multipatch data is established, which provides true 3D data for WebGIS and reflects the real world. Thirdly, through the research of ArcSDE, the way of connecting Oracle database through ArcSDE is established. Through the connection of ArcSDE, the compatible support for many kinds of databases can be realized, and the convenient management of large amount of spatial data in relational database can also be realized. This is of great significance to the construction of distributed data source, three dimensional WebGIS with B / S structure. Fourth, through the research of SOE (Server Object Extension), the network publishing of Multipatch data service is established, and through this service, the Multipatch data can be accessed, and the key problem of 3D model in browser is solved.
