Center for Advanced Spatial Analysis

CASA is run under the Directorship of Michael Batty, Professor of Spatial Analysis and Planning (UCL). He was previously Director of the SUNY Buffalo site of NCGIA (1990-1995) and was Professor and Head of the Department of City and Regional Planning in the University of Wales at Cardiff from 1979 until 1990.

He has Degrees from the University of Manchester (BA) and Wales (PhD), is a Fellow of the British Academy as well as a Fellow of the RTPI, CIT and RSA. His research is in the development of computer based technologies, specifically graphics-based and mathematical models for cities, and he has worked recently on applications of fractal geometry and cellular automata to urban structure.

We have begun a project (The Geography of Scientific Citation) to examine the density and distribution of scientific knowledge in space and our first attack on this problem looks at the geography of scientific citation. We know from more casual evidence that the bigger the place, the greater the probability of there being highly cited scientists working there. The Institute of Scientific Information who produce the world's citation counts have recently developed a list of the most highly cited scientists which is available at http://isihighlycited.com/. We have used this list, with their permission, to begin an analysis of geographical concentration.

What we are finding is that the concentration of the most highly cited is dramatically higher than we would have expected. For places, it is higher than for institutions and when we aggregate to countries, the concentration is higher still. 66 percent of the 'highly-cited' work in North America, with a third of these (22 percent) in just three places: the Bay Area, Boston, and Washington DC.

Atlas of Cyberspace
Martin Dodge is CASA's Cyberspace expert. He has co-authored Atlas of Cyberspace and Mapping Cyberspace with Rob Kitchen and was recently interviewed for the magazine Darwin.

Atlas of Cyberspaces
The Atlas of Cyberspaces is an atlas of maps and graphic representations of the geographies of the new electronic territories of the Internet, WWW and other emerging Cyberspaces. These maps of Cyberspaces - cybermaps - help us visualise and comprehend the new digital landscapes on our computer screen and in the wires of the global communications networks, aiding our navigation to our information destinations. The cybermaps in this atlas have been created by 'cyber-explorers' from many different disciplines from all around the world.

The Geography of Cyberspace
The Geography of Cyberspace is a comprehensive directory of information on all aspects of the geographies of the Internet, World-Wide Web and emerging Cyberspaces.

Modelling Cyberspace
Modelling Cyberspace is an analytical approach to the structure of cyberspace. It focuses on the unique spatial characteristics of cyberspace where its structure is determined purely by the topological arrangement. With the aid of such features, we aim to realise a more comfortable, intuitively comprehensive virtual space.
