A retrospective assessment of Fotheringham, Batty and Longley's (1989) diffusion-limited aggregation (DI.A) analogue model of urban growth is assessed and a dataset which facilitates empirical evaluation of this analogy is developed.
Abstract
ABSTRACT The innovation of computer graphics into regional science has already stimulated development of new types of analogue models of city structures. Now, progressive integration of satellite data and socio-economic information within geographical information systems (GIS) is making possible the creation of tailor-made datasets through which such models might be evaluated. This paper begins with a retrospective assessment of Fotheringham, Batty and Longley's (1989) diffusion-limited aggregation (DI.A) analogue model of urban growth. Using satellite imagery and a surface model derived from the UK Census, we develop a dataset which facilitates empirical evaluation of this analogy. Implications of this approach are explored.
