[Termes IGN] mise à jour de base de donnéesRésumé : (auteur) Nowadays, users often use topographic data to reference their own thematic data. When reference data are updated or if the user wants to replace the reference, the thematic data have to be processed in order to maintain data consistency. We call this processing thematic data migration. This paper proposes an updated version of a previously proposed thematic data migration process, which includes the case where the relations between thematic and topographic data have to be modified between the initial and the final state. A model to describe the relations and their modifications is proposed. A multi-criteria decision method is used to relocalise the thematic data on the topographic data guided by the described relations. The whole process is illustrated on a running example, on which obtained results are presented and discussed.

[Vedettes matières IGN] GénéralisationMots-clés libres : cartographic generalisation constraints modelling spatial environment multi-agent communicative agents topographic data Résumé : (auteur) Our research is concerned with automated generalisation of topographic vector databases in order to produce maps. This article presents a new, agent-based generalization model called CARTACOM (Cartographic generalisation with Communicating Agents), dedicated to the treatment of areas of low density but where rubber sheeting techniques are not sufficient because some eliminations or aggregations are needed. In CARTACOM, the objects of the initial database are modelled as agents, that is, autonomous entities, that choose and apply generalisation algorithms to themselves in order to increase the satisfaction of their constraints as much as possible. The CARTACOM model focuses on modelling and treating the relational constraints, defined as constraints that concern a relation between two objects. In order to detect and assess their relational constraints, the CARTACOM agents are able to perceive their spatial surroundings. Moreover, to make the good generalisation decisions to satisfy their relational constraints, they are able to communicate with their neighbours using predefined dialogue protocols. Finally, a hook to another agent-based generalisation model – AGENT – is provided, so that the CARTACOM agents can handle not only their relational constraints but also their internal constraints. The CARTACOM model has been applied to the generalisation of low-density, heterogeneous areas like rural areas, where the space is not hierarchically organised. Examples of results obtained on real data show that it is well adapted for this application.

[Vedettes matières IGN] GénéralisationMots-clés libres : automated generalisation rule revision trial and error strategy Résumé : (auteur) Automating the generalisation process, a major issue for national mapping agencies, is extremely complex. Several works have proposed to deal with this complexity using a trial and error strategy. The performance of systems based on such a strategy is directly dependent on the quality of the control knowledge (i.e. heuristics) used to guide the trials. Unfortunately, most of the time, the definition and updation of knowledge is a fastidious task. In this context, automatic knowledge revision can not only improve the performance of the generalisation, but also allow it to automatically adapt to various usages and evolve when new elements are introduced. In this article, an offline knowledge revision approach is proposed, based on a logging of the system and on the analysis of outcoming logs. This approach is dedicated to the revision of control knowledge expressed by production rules. We have implemented and tested this approach for the automated generalisation of groups of buildings within a generalisation model called AGENT, from initial data that reference a scale of approximately 1:15,000 compared with the target map's scale of 1:50,000. The results show that our approach improves the quality of the control knowledge and thus the performance of the system. Moreover, the approach proposed is generic and can be applied to other systems based on a trial and error strategy, dedicated to generalisation or not.

[Vedettes matières IGN] GénéralisationMots-clés libres : Knowledge revision Problem solving Trial and error method Cartographic generalisation Résumé : (auteur) Humans frequently have to face complex problems. A classical approach to solve them is to search the solution by means of a trial and error method. This approach is often used with success by artificial systems. However, when facing highly complex problems, it becomes necessary to introduce control knowledge (heuristics) in order to limit the number of trials needed to find the optimal solution. Unfortunately, acquiring and maintaining such knowledge can be fastidious. In this paper, we propose an automatic knowledge revision approach for systems based on a trial and error method. Our approach allows to revise the knowledge off-line by means of experiments. It is based on the analysis of solved instances of the considered problem and on the exploration of the knowledge space. Indeed, we formulate the revision problem as a search problem: we search the knowledge set that maximises the performances of the system on a sample of problem instances. Our knowledge revision approach has been implemented for a real-world industrial application: automated cartographic generalisation, a complex task of the cartography domain. In this implementation, we demonstrate that our approach improves the quality of the knowledge and thus the performance of the system.
