: This paper presents a Geospatial 3D Visualization and Collaboration System that was developed using object-oriented system design methodology. This system integrates software engineering, visualization technology with World Wide Web technology to enable production, dissemination and use of 3D imagery and geospatial information on a hierarchical level through the WWW. Several visualization modules were developed using the Model View-Controller design pattern technology. These modules are plug-in and reusable components for other similar applications. The application results demonstrate that using object oriented system design and Model-View-Controller design pattern provides a great chance for software reuse and increase the system flexibility.
