Paper Abstract:	The integration between Geographic Information System and Internet gives the opportunity for everyone who wants to use GIS data and functions without installing any proprietary GIS software. Recently, these have been some researches about three dimensional WebGIS systems originated from the idea that GIS should become more familiar and realistic to end-users. However, these researches have limitation in analyzing maps’ information and focusing on 3D maps conversion only. In this paper, we will propose the method to construct a three dimensional WebGIS system namely as SGIS-3D based on Digital Elevation Model- DEM and Geographic Modelling Language GeoVRML. Our system also provides some Spatial Analysis operations to exploit information in 3D maps. It is useful for managers, researchers and students who want to explore visual 3D maps for their own specific tasks.
