[Vedettes matières IGN] CartologieRésumé : (auteur) The clutter effect occurs when there is an excessive amount of information in a map or when this information is disorganized. Better measuring clutter is essential to improve the quality of outputs of automated cartography systems. This paper reviews some existing methods for measuring clutter from different research communities, highlighting the lacks for automated mapping. Three use cases are presented to show what kind of clutter measures are required to go further with the automation of map design, particularly in generalization, in symbol/style specification and in Volunteered Geographic Information mapping.

The article describes the land-use simplification method developed, the strategy used to manage generalization on large areas, and the way to formalize multi-scales land-use generalization rules in the ScaleMatsre2.0. Finally, an experiment is provided on two datasets to illustrate the proposition: a land-use coverage in the area of Dakar (Senegal) and a map of sedimentary floor off the coast of Brittany (France).

[Vedettes matières IGN] GénéralisationMots-clés libres : benchmark evaluation learning summarization Résumé : (auteur) [introduction] Map generalization is often considered as a cognitive task similar to text summary. Like text summary, generalization seeks to reduce the level of detail of initial data, highlighting the important features regarding a given need, and preserving the main characteristics of the initial data (Ruas 2002). The automation of text summarization is key research topic for language processing scientists, and it should be interesting to verify if the similarities in the human cognitive process lead to similarities in the automation techniques. Moreover, text summarization is a part of the multimedia summarization problem that also includes video and music summarization, and this complete literature is interesting to review. The aim of the paper is also to identify some guidelines for further map generalization research that can be derived from the multimedia summarization research community. This paper first identifies similarities and differences in both automation problems. Then, section 3 proposes ideas from multimedia summarization that could be beneficial for the map generalization community. Finally, the paper is concluded with some ideas for further research opportunities.

With the advent of projects like OpenStreetMap, data users are increasingly confronted with the task of dealing with heterogeneously detailed and scaled geodata. Knowing the scale of geodata is very important for mapping processes such as for generalization of label placement or land-cover studies for instance. In the following chapter, we review and compare two concurrent approaches at automatically assigning scale to OSM objects. The first approach is based on a multi-criteria decision making model, with a rationalist approach for defining and parameterizing the respective criteria, yielding five broad LoD classes. The second approach attempts to identifiy a single metric from an analysis process, which is then used to interpolate a scale equivalence. Both approaches are combined and tested against well-known Corine data, resulting in an improvement of the scale inference process. The chapter closes with a presentation of the most pressing open problems.

[Vedettes matières IGN] GénéralisationRésumé : (auteur) Multi-level MAS have become a growing research topic in the last years. Due to the diversity of proposed models, we claim that recurrent situations have to be identified and characterized in an abstract way, in order to allow formal comparisons between existing models and to facilitate the design of new models. Therefore, we propose a first list of multi-level MAS patterns, coming from an attempt to unify several multi-level MAS models dedicated to a spatialized problem solving (cartographic generalization). The structure and dynamic of each pattern are formally described, and illustrated through examples drawn from the context of cartographic generalization and other MAS applications (especially in simulation). We also discuss the possibility to re-use and compose those patterns.
