摘 要: GIS互操作研究是当前地理信息系统研究的热点,介绍了GIS与VR之间数据互操作技术;提出了基于XML和VR技术相结合的虚拟GIS可互操作模型,具体阐述了XML在虚拟GIS中信息共享的扩展及数据互操作应用,采用X3D编码虚拟地理数据可以较好地实现虚拟GIS数据的互操作,最后设计并实现了虚拟GIS原型系统,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。 Research on GIS interoperability is a characteristic in GIS study currently. Introduced within GIS and VR data interoperability, Put forward virtual GIS interoperability model combinative the XML and VR technology , Concrete expound in the virtual GIS with XML for the information share expand and data interoperability ,Adopted the X3D to implement the virtual GIS system, Finally test and estimate the prototype system , The testing indicated the prototype system preferably to settle the share of geography information and the interactive problem.
