Dear colleagues, We had hoped to present our work using Visibility Graph Analysis at the coming space syntax symposium but, unfortunately, increased work commitments make it impossible for us to attend. This email is to suggest a collaborative research proposal that I was going to raise in Atlanta, which may be of interest to anyone investigating the effects of spatial structure on the functionality of buildings and urban areas. From our own experience as a planning consultancy, we find Visibility Graph Analysis (VGA) a powerful method for quantifying the functional characteristics of spatial layouts and we use this technique for pedestrian modelling and design evaluation. For this purpose we developed 'Fathom' Visibility Graph Analysis software which has been specially designed to process large buildings and urban areas (http://www.intelligentspace.com/software ). We are now keen to apply the software beyond the requirements of our day to day work, by testing it on very large spatial systems such as whole cities. If there are any researchers looking at large scale urban data (land use, land value, pedestrian movement etc) who are interested in collaborating on a research proposal to apply Visibility Graph Analysis to a city, please do get in touch with me. Our client and friend Gordon Brown from Space Analytics in Denver is attending the symposium and has kindly offered to present our paper on my behalf. The paper will also be in the proceedings and if anyone would like to ask any questions about it or get a colour pdf copy, you are most welcome to contact us or drop by and visit us if in London. Best wishes for a stimulating symposium, Jake _____________________________ Dr. Jake Desyllas Partner Intelligent Space 68 Great Eastern Street London EC2A 3JT t: +44 (0) 20 7739 9729 f: +44 (0) 20 7739 9547 e: [log in to unmask] w: http://www.intelligentspace.com
