title Assessing the Role of Computer Visualisation in Planning Control: a recent case study
source Timmermans, Harry (Ed.), Third Design and Decision Support Systems in Architecture and Urban Planning - Part two: Urban Planning Proceedings (Spa, Belgium), August 18-21, 1996
summary In papers to previous DDSS Conferences, and elsewhere, the author has developed an argument concerning the use of computer visualisation in the planning process. In essence, it proposes that: visualisation can enable lay persons to play a more effective role and this can result in different and more effective decisions; the level of realism employed should result from the basic requirements necessary to resolve the issue minimising the cost of production of the images. These points have been tested in repeated examples. The latest one concerns a new site that Anglia Polytechnic University has established in the centre of Chelmsford, UK. A computer model of the new campus showing both the existing and proposed buildings was commissioned from the author by the University for a visit by HM the Queen in June 1995. This model was subsequently adapted for use in the process of obtaining planning consent and the marketing of floorspace for the next building to be constructed. For this purpose, a higher level of realism was requested. The experience of achieving it confirmed the results of the previous research indicating the strong link between realism and cost. It also contributed new insights into the varying expectations of different professionals concerning the role of such a visualisation. The requirement of the architect for demonstrating all aspects of the design required a high level of realism than that required for planning and marketing purposes and was considerably more expensive. The low cost of use for planning purposes should be stressed but surprisingly, the lower level of realism implied may be easier for the lay person than the professional to accept.
