【摘要】 介绍了X3D规范和WebGIS新特点;采用X3D技术设计交互式三维虚拟WebGIS原型系统体系结构,提出了一个基于X3D的三维虚拟WebGIS原型系统,并进行了试验研究。该原型系统以符合X3D的XML格式进行数据存储和传输,采用X3D技术最终来实现交互式三维虚拟WebGIS原型系统,最后对WebGIS原型系统的运行测试及评价,测试表明该原型系统较好地解决地理信息共享与互操作问题。更多还原

【Abstract】 This paper introduced X3D specification and the new characteristic of WebGIS, Used the X3D to design interactive 3DMWebGIS prototype system, Presented a based on X3D 3DM WebGIS prototype system, and processed to test. The prototype systemaccord with the XML of X3D format to process the data for storage and transmission, Adopted the X3D to implement 3DM WebGISsystem, Finally test and estimate the prototype system , The testing indicated the prototype system preferably to settle the share ofgeography information and the interactive problem.更多还原
