Abstract : Rapid technological growth in developments of web based geographical information systems, visualization (tours, flythrough) and navigation with 3D models plays a vital role in the application of geographical information systems. The purpose of this study is to build an interactive system and deploy a platform to visualize, navigate, analyze, and interact the 3D city models stored on the 3D city Database via web supporting which can easily access and enhance the effectiveness of 3D web-based Geographical Information System (GIS) and gives an experience and information for user needs with the ability to do with 3D data. City GML (XML-based standard) data model is used for the representation of 3D urban objects. In this context, the buildings are composed as textured 3D model by using softwares (Arc scene, Google sketch up) and stored in cityGML format which access massive rendering of large number of objects and conservation of geometry semantic properties. Integration of Google Earth and Google Maps API which aims to get 3Dcity models and attribute data of the Area of interest by using XML databases andto create a web based 3D geospatial application.
