[Vedettes matières IGN] GénéralisationRésumé : (Auteur) Database generalisation is a process which aims at producing a geographic database from an initial geographic database in order to satisfy new needs. Starting from the study of an actual database generalisation process developed at the Ministere des Ressources Naturelles of Quebec (MRNQ), our intention was to formalise the cartographic knowledge contained in the process to make it reusable. MRNQ's process has the form of a workflow which contains a list of actions applied to object classes. Since we wanted to extract generic knowledge, we introduced the notions of problem and operation: our assumption is that the cartographic knowledge formalised using these two notions is generic enough to be applied to other cases of generalisation. Thus, we propose a causal graph which associates a set of problems to a set of operations. The utility of such a model is that it offers an explanation for each actions contained in the workflow and allows an anticipation of future problems when creating a new workflow.
