Visualizing the city: communicating urban design to planners and decision-makers.
(CASA Working Papers
UCL (University College London), Centre for Advanced Spatial Analysis: London, UK.
There are now a wide array of new digital tools that are able to support the generic activity ofplanning and design. In urban design, these tools support different stages of the planningprocess which involve rapid and effective storage and retrieval of information, various kindsof visualization which inform survey and analysis as well as design itself, and differentstrategies for communicating information and plans to various publics from designprofessionals to the affected community. In this paper, we begin by noting the activities thatsuch digital tools can support, emphasizing methods of visualization, and specifically focusingon integrated 2d mapping and 3d block modeling. We then review the state-of-the-art, worldwide,suggesting that there are rapid changes taking place in how such visualizations are beingdeveloped. We note developments in remotely sensed survey and in the development of 3dmodels integral to spatial databases as reflected in geographic information systems (GIS) incontrast to computer?aided design (CAD). We illustrate these ideas with respect todevelopments in world cities, specifically London, where we review initial attempts at thedesign of virtual cities. We then show two related but different ways of constructing suchmodels: first in ad hoc fashion by linking various proprietary software based on internet GIS,rapid photorealistic CAD, and panoramic imaging; and second through a tighter couplingbetween 2d and 3d GIS which is highly suited to the new digital data from remote sourcessuch as LIDAR (LIght Detection And Ranging). We conclude with a discussion of differentways in which these visualizations might be automated and delivered to users, in stand-alonemanner or over the net.
