Geosimulation is hailed as 'the next big thing' in geographic modelling for urban studies. This book presents readers with an overview of this new and innovative field by introducing the spatial modelling environment and describing the latest research and development using cellular automata and multi agent systems. Extensive case studies and working code is available from an associated website which demonstrate the technicalities of geosimulation, and provide readers with the tools to carry out their own modelling and testing. This is the first book to treat urban geosimulation explicitly, integrating socio economic and environmental modelling approaches. It provides the reader with a sound theoretical base in the science of geosimulation as well as applied material on the construction of geosimulation models. There are cross references to an author maintained associated website with downloadable working code for readers to apply the models presented in the book.
