By the IP locating associated with network attributes acquisition, an internet “resource and object” spatial database was established in this paper in order to combine the cyberspace and realspace together. Then it was layered and partitioned, and projected into the three-dimensional coordinate system of digital earth. Functions such as positioning, query, analysis and visualization for 3D CyberGIS virtual-reality integration were implemented, which could effectively expand the GIS management capabilities to the virtual space elements.
