Abstract: This paper firstly introduces the features of Web VRGIS (virtual reality Web geographic information system) based on VRML, then discusses the core contents of it such as spatial data engine, basic spatial element on VRML, the GIS hierarchy management on VRML and spatial data analyses on VRML, etc. At last, a framework of Web VRGIS based on VRML is put forward, and a simple experiment system and its analyses are given. ;;
