Publicparticipation is very important for the success of an urbanplanning project, since anyurbanplanning project will ultimately become part of the everyday life of the public. Most members of the general public are not urbanplanning professionals; therefore, well-designed visualization andinteractive tools can help expand their participation in urbanplanningprocesses. The emerging technology of virtualglobe-based3Dvisualization is a unique opportunity to facilitate publicparticipationin urbanplanning projects by promoting intuitive 3D interaction, instant interoperability and seamless integration of 3Dvisualization with other traditional text and multimedia information channels. This paper discusses the technical issues of developing avirtualglobe-based3Dvisualizationframework for publicizing urbanplanning information, using Web Services and Service Oriented Architecture (SOA) to support visual planning model sharing and interoperability. With 3D photorealistic visualization, end users can conveniently obtain both the macro-vision of a project on the global scale and the micro-details on the street scale, using swift zooming tools like Google Earth. End users can select any availableurbanplanning solution for visual investigation and comparison in avirtualglobe-based3Dvisualizationenvironment. The service oriented architecture allows urbanplanning information to be deployed as aservice in one server or several geographically distributed servers, or even from the end user’s own computer. With the architecture’s capability for integrating distributed resources, other traditionalinteractive functions such as labeling, BBS, forum, and email, can also be conveniently integrated into the system. Auxiliary spatial analysis tools are integrated to help end users perform “professional” tasks such as sunlight analysis and 3D distance measurement. This highly distributed system is designed for the Internet; therefore, any personal computer connected to the Internet can easily access the system and participate in the interaction.
