[Termes IGN] utilisation du solRésumé : (Auteur) Different processes shaping land-use patterns are observed at different scales. In land-use modelling, scale can influence the measurement and quantitative description of land-use patterns and can therefore significantly impact the behaviour of model parameters that describe land-use change processes. We present results of a rigorous sensitivity analysis of a cellular urban land-usechange model, SLEUTH, testing its performance in response to varying cell resolutions. Specifically, we examine the behaviour of each type of urban growth rule across different cell sizes, and explore the model's ability to capture growth rates and patterns across scales. Our findings suggest that SLEUTH's sensitivity to scale extend beyond issues of calibration. While the model was able to capture the rate of growth reliably across all cell sizes, differences in its ability to simulate growth patterns across scales were substantial. We also observed significant differences in the sensitivity of the growth rules across cell sizes, indicating that SLEUTH may perform better at certain cell sizes than at others. These findings emphasize the importance of scale considerations in land-use-change modelling research, particularly in terms of determining the relevant and appropriate scales of enquiry for the processes being simulated.

[Termes IGN] système d'information géographiqueRésumé : (Auteur) We parameterized neural net-based models for the Detroit and Twin Cities metropolitan areas in the US and attempted to test whether they were transferable across both metropolitan areas. Three different types of models were developed. First, we trained and tested the neural nets within each region and compared them against observed change. Second, we used the training weights from one area and applied them to the other. Third, we selected a small subset (- 1 %) of the Twin Cities area where a lot of urban change occurred. Four model performance metrics are reported : (1) Kappa; (2) the scale which correct and paired omission/commission errors exceed 50%; (3) landscape pattern metrics; and (4) percentage of cells in agreement between model simulations. We found that the neural net model in most cases performed well on pattern but not location using Kappa. The model performed well only in one case where the neural net weights from one area were used to simulate the other. We suggest that landscape metrics are good to judge model performance of land use change models but that Kappa might not be reliable for situations where a small percentage of urban areas change.

[Termes IGN] prédictionRésumé : (Auteur) This paper compares two land change models in terms of appropriateness for various applications and predictive power. Cellular Automata Markov (CA-Markov) and Geomod are the two models, which have similar options to allow for specification of the predicted quantity and location of land categories. The most important structural difference is that CA-Markov has the ability to predict any transition among any number of categories, while Geomod predicts only a one-way transition from one category to one alternative category. To assess the predictive power, each model is run several times to predict land change in central Massachusetts, USA. The models are calibrated with information from 1971 to 1985, and then the models predict the change from 1985 to 1999. The method to measure the predictive power: 1) separates the calibration process from the validation process, 2) assesses the accuracy at multiple resolutions, and 3) compares the predictive model vis-A-vis a null model that predicts pure persistence. Among 24 model runs, the predictive models are more accurate than the null model at resolutions coarser than two kilometres, but not at resolutions finer than one kilometre. The choice of the options account for more variation in accuracy of runs than the choice of the model per se. The most accurate model runs are those that did not use spatial contiguity explicitly. For this particular study area, the added complexity of CA-Markov is of no benefit.

The methodology is applied to processes of residential spread in a part of the commuting periphery of Brussels. The model hypothesizes that households effect on urban development, through their valuation of neighbourhood externalities. A coarse sensitivity analysis is undertaken in order to explore the relationship between household neighbourhood preferences and emerging spatial morphologies. These macro structures are measured with different indices in order to parameterize the model.

[Termes IGN] temps instantanéRésumé : (Auteur) This paper is about the information-theoretic foundations upon which useful explanatory and predictive models of dynamic geographic phenomena can be based. It traces the development of these foundations, from sequences of temporal snapshots, through object life histories, to event chronicles. A crucial ontological distinction is drawn between 'things' and 'happenings', that is between continuant and occurrent entities. Up to now, most research has focused on representing the evolution through time of geographic things, whether objects or fields. This paper argues that 'happenings' should be upgraded to an equal status with 'things' in dynamic geographic representations and suggests ways of doing this. The main research focus of the paper is the application of an algebraic approach, previously developed mainly in the context of computational processes, to real-world happenings. It develops a pure event-oriented theory of space and time, and suggests the possibilities that the theory provides by using it to represent the motion of a vehicle through a region. The paper contains a discussion of the scalability and applicability of this model to geographic domains and illustrates some of the ideas by reference to a geo-sensor example. The paper concludes by summarizing its main ideas, relating the research to other germane areas not covered in the developmental survey, and indicating directions for future work.
