Geosimulation is a catch-all phrase that can be used to represent a new wave of spatial simulation modeling that has come to the fore in very recent years. Besides traditional urban modeling and simulation, the intellectual roots of geosimulation derive from recent developments in computer science and geographic information science. The geosimulation approach draws together a diversity of theories and techniques, offering a unique perspective that traditional simulation has commonly lacked: a view of urban phenomena as a result of the collective dynamics of interacting objects, often represented at the scale of individual households, people, and units of real estate and at time-scales approaching "real time".
