The generation of 3D VRML urban area models from GIS for planning information systems

摘要

The Unviersity of the West of England, (UWE) modelled part of Bristol for a Virtual Reality (VR) experience to demonstrate millennium landmark proposals. UWE later modelled the environs of the Tower of London to support bids for fuding and to provide the context for judging the visual impact of iterative design development. All structures, hard landscape and tress were modeling in 3D down to street furniture, railings and kerbs. Further research continued to develop more effective approaches to historic building maintenance management, vistor management and interpretation of historic sites to visitors Piecing in new Computer Added Architecture Design, (CAAD) models received from Architectural Practices to visualise them in context as part of the planning negotiation process has often taken staff several days of work for each instance. Data conversion and amalgamation from all the diverse sources was the major impediment oto effective group working to create the models. It became apparent that a Geographic Information System, (GIS) would assit retrieving all the appropriate data that described the part of the model under creation. It was possible to predict that management of many historic part models stepping back through time, allowing for different expert interpretations to co-exist, would be in itself a major task requiring a spatial database (GIS).
