一种三维无插件展示空间数据服务的体系研究

Research on a 3D Non Plug-in Display Spatial Data Service System

通过研究webGL技术和OGC相关标准,提出了一种构建三维无插件空间数据服务体系的方法。该方法在复用地理空间数据服务的基础上,提供三维无插件浏览方式,可极大提高了用户体验。论文以丹阳市城市地质空间数据为研究对象构建了原型系统,设计了体系架构、数据存储结构及分类,从原型系统实现上介绍了开发环境、WMS数据服务的发布等过程,实验证明,该体系可在浏览器中提供良好的交互式三维可视化体验,同时,能够将OGC相关服务标准集成展示,可以在空间数据服务中推广使用。

By studying webGL technology and OGC related standards,a method of constructing three-dimensional plug-in-free spatial data service system is proposed.Based on the reuse of geospatial data services,this method provides three-dimensional plug-in-free browsing mode,which greatly improves the user experience.Taking DanYang City Geological Spatial Data as the research object,this paper constructs the prototype system,designs the architecture,data storage structure and classification,introduces the development environment and the publishing process of WMS data service from the prototype system implementation.The experiment proves that the system can provide good interactive three-dimensional visualization in browsers.Experience,at the same time,can integrate and display OGC related service standards,can be promoted in the use of spatial data services.
