[Vedettes matières IGN] GénéralisationRésumé : (Auteur) OpenStreetMap data comprise of very detailed (e.g. zebra crossing) and quite rough features (e.g. built-up area). But making large scale maps from data with inconsistent level of detail often blurs map comprehension. This paper explores the automatic harmonization of OpenStreetMap data for large scale maps, i.e. the process that transforms rough objects to make them consistent with detailed objects. A typology of the new operators that harmonization requires is presented and six algorithms that implement the operators are described. Experiments with these algorithms raise several research questions about automation, parametrization, or the level of abstraction of the transformation, which are discussed in the paper.

[Termes IGN] variable visuelleRésumé : (auteur) Environmental noise is a major concern for city dwellers, however, actual noise maps are not adapted to them. The work described here is developed in the context of the CartASUR project which specifically addresses these deficiencies of noise maps. CartASUR collected perceptual data in several places of Paris using a survey and aiming to define new urban soundscape indicators to offer the possibility of several interpretations depending on the users’ personal and cultural characteristics, and to show them on maps. In this chapter, the indicators sound pleasantness and global loudness are presented. Several cartographic proposals are made to portray indicators during one, two, or three periods (day, evening, night) on maps, and their characteristic features (symbol design, visual variables) are discussed. Cartographic proposals are assessed through a survey which addresses the understanding of cartographic symbols and global properties of maps. The survey concludes that map readers prefer to view complete (both sound pleasantness and global loudness) and precise (three measurement periods) information, even when the amount of information leads to complex maps, which are considered the most attractive and useful. Nevertheless, the survey shows that these complex maps are not well interpreted by a large part of map readers. Use of visual variables color and quantity is discussed and proposals are made to improve symbol understanding.
