Kent (and colleagues):
This line of research is pretty well-developed now. (Of course it builds on the back of a long line of developments in the geographical sciences.) The theoretical and methodological foundations for connecting agent automata and cellular automata through Geographic Information Science (and not just systems) are described in:
Torrens, P.M. & Benenson, I. (2005) Geographic Automata Systems. International Journal of Geographic Information Science, 19(4): 385-412.
Benenson, I. & Torrens, P.M. (2004) Geosimulation: Automata-Based Models of Urban Phenomena. Chichester: John Wiley & Sons.
A practical example of how to do it is described in:
Benenson, I. & Torrens, P.M. (2004) A minimal prototype for integrating GIS and geographic simulation through Geographic Automata Systems. In GeoDynamics, P. Atkinson, G. foody, S. Darby, F. Wu (Eds.) Florida: CRC Press, pp. 347-369.
Its usefulness as an applied concept is described in:
Torrens, P.M. (2007) A geographic automata model of residential mobility. Environment & Planning B, 34(2): 200-222.
Torrens, P.M. (2006) Simulating sprawl. Annals of the Association of American Geographers 96(2): pp. 248275.
Its significance for challenges in GI Science and spatial modeling is discussed in:
Albrecht, Jochen. 2005. A new age for geosimulation. Transactions in Geographic Information Science 9 (4):451454.
Software developed on the scheme of Geographic Automata Systems, with a full tight-coupling to GIS has been developed by Benenson and is available (free) at:
