In the Virtual Reality technologys application, the technical standard of construction of Virtual Reality system with Web GIS based on 3D Virtual Graphics based on the XML (Extensible Markup X3D technology, need to meet the following characteristics: First, Language)-X3D was proposed by Web3D Alliance. It is proposed the client software must be easy to integrate with common Web the feasible model of Virtual Reality Geographic Information browser, and the users can access to the system through a System which based on Browser/Service structure, through a large common browser or a plug-in directly. Second, the real-time number of researches on the current application, include performance of Virtual Reality System requires the graphics file Browser/Service structure, Virtual Reality technology and GIS. as small as possi
