=====GIS, Spatial Analysis, and Modeling===== |David Maguire, Michael Batty, Michael Goodchild, editors| 2005| {{ http://www.leg.ufpr.br/~pedro/figures/gis-maguire.jpg}} ====GIS, Spatial Analysis, and Modelling Overview==== |Goodchild, M.F.| GIS are not well suited to dynamic modelling. ====Approaches to Modelling in GIS: Spatial Representation and Temporal Dynamics==== |M. Batty| When dynamic predictive models are embedded within GIS, then the software in question is usually customized to the specific process in question. [...] Softwares such as this [PCRaster], in fact, is conceived with physical rather than human process in mind. In CA modelling, for example, regular cells are usually the storage bins for aggregations of individuals, [...] This collection of agents act as an attribute of the cell rather than being a collection of agents in their own right. [...] Diffusion is simulated by showing how cells states change rather by showing how agents actually move. **CA models might be seen as ABM when the agents are fixed or immobile in the simulation sense.** ====Linking General-Purpose Dynamic Simulation Models with GIS==== |I. Miller, S. Knopf and R. Kossik| The software architecture required for ABM is significantly different from that required for just modeling the evolution of geographic entities in a static map. Dynamic models typically produce two types of time sequences as results: - longitudinal time histories of individual values - snapshots of the entire system (movies) ====Transition Potential Modeling for Land Cover Change==== |J.

Parker| This chapter summarizes the activities, concerns, and challenges of developers and end users of ABM/LUCC. Many ABM/LUCC researches begin by developing models that operate over an abstract landscape, even when their longer-term goals include application to real-world landscapes. Some interesting references about integration. Types of integration: - abstract cellular landscapes - GIS initialization/output display - integration via files written to disk - run-time communication - internal GIS functionality in ABM A Wishlist for model integration: ^ modelling functionality |object oriented structure. interface with other dynamic models. mobile objects. visualize in 3D | ^ mathematical functionality | potentially needed for constructing agent decision-making, model calibration and coupling with environmental process. finite-element modelling, integer programming, genetic algorithms, simulated annealing | ^ verification and validation | real-time visualization, on-the-fly sensitivity analysis by changing model parameters, generate and export graphics | ^build-in standard functions | well documented algorithms for all the above functionalities | A call for a standard base modelling framework for ABM/LUCC. ====Towards a GIS Platform for Spatial Analysis and Modelling==== |Maguire, D.J.| GIS are not well suited to dynamic modelling.
