中文摘要：

针对当前网络空间与现实空间研究分离之不足,通过IP定位及相关网络属性采集,建立互联网资源及用户空间数据库,分层分区投影到三维数字地球复合坐标系中,实现三维CyberGIS＂虚拟―现实＂一体化定位、查询和分析功能,有效拓展了地理信息服务（Geographic Information System,GIS）对虚拟空间要素的集成管理能力。

英文摘要：

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.
