Abstract
Urban Growth as a Spatiotemporal Diffusion Process Track: Modeling Author(s): Jay Lee, Milton Harvey The process of urbanization is a complex phenomenon that has both spatial and temporal dimensions. With the proliferation of GIS technology and data available at micro scale, it is now possible to quantitatively model urban sprawl as a spatiotemporal phenomenon. Relating to classic theories of suburbanization, we examine the process of sprawling growth of urbanized areas first by lumping the process into a one dimensional spatiotemporal pattern and then expanding it to a two dimensional and finally a three dimensional pattern that are capable of accounting the spread and backwash of urban sprawl. This study uses a GIS database of land parcels in Geauga County of northeast Ohio. This county is in the midst of a significant sprawl of urbanized areas as impacted by the expanding Cleveland Metropolitan region. It has seen significant population growth and high rates of converting vacant lands into built lands. It provides an ideal testbed for developing and calibrating a quantitative model for urban sprawl.
