A constrained cellular automata (CA) model based on 'grey cells' for the simulation of different types of urban forms and developments is developed within a raster GIS. Remote sensing and GIS are used to supply information on environmental constraints and locations of growth centers for the...

Most cellular automata (CA) urban models assume densities to be uniform for all cells. This is not true in real cities because densities vary substantially from city to city and from urban center to periphery areas. Development density, which affects urban form, is an important factor in urban...

Rapid land-use change has taken place in China since economic reform. A significant amount of agricultural land has been encroached on by urban development in many coastal cities, especially in the Pearl River Delta. This has caused severe land-use problems because China is among the nations...
