Résumé :	(auteur) This paper is based on collaboration between two institutes with the goal to test research processes on road network generalization in a real production context. The first tested algorithms were only based on the data geometry as it is usually described in literature, with unsatisfying results. Then major improvements were brought by taking into consideration se-mantic information, with much better final results. The conclusion asks the question of the duality between genericity and data schema dependence.

Résumé :	(auteur) In the past few years the mobile phone data are considered as a useful complementary source of information for human mobility research. In this paper, we focus on the computation of the Origin Destination matrix using mobile phone data. First, a new approach of OD matrix design which takes into account the spatiotemporal heterogeneities of mobile phone data is proposed. Second, some analysis allowing measuring the effect of spatio-temporal filtering on the OD matrix results are carried out.

Résumé :	(auteur) Making on demand maps is a problem which is shared by plenty of national mapping agencies. One strategy to help a map maker to make his/her map is based on analogy. This strategy requires a large example base. Thus, the point is to explore this map base in order to offer the map maker a reasonable number of relevant examples. In this paper, a survey which aims to: i) evaluate the visual global properties of topographic map examples and ii) make groups of maps which will be offered to mapmakers in the software interface is presented. The results i.e. the map groups qualified by their visual properties are shown.

Résumé :	(auteur) Geoportals and cartographic applications provide heterogeneous geographic data such as topographic maps or orthoimagery layer and lead to various geovisualization applications. In this paper, our purpose is to analyze advantages and drawbacks of both representations and to look for methods to design in-between representations mixing, blending or merging them. This design will be guided by the results of our study of geovisualizations in use in websites based on the French geoportal (Hoarau 2012). Can we learn from one representation to improve the other one or merge their strengths? This paper outlines why it is a great opportunity to use topographic maps and orthoimagery together to design in-between representations without scrambling initial information. One key issue is then how can we blend both representations to design in-between representations. In this paper we will explore how to go beyond the single use of transparency to superimpose images and maps, as traditionally encountered in numerous geoportals. Could we use the photorealism of orthoimagery data in order to texture empty areas of topographic maps and make them more expressive (Patterson 2002)? Could we use graphic rendering tools in order to make maps more natural (Jenny 2012)? Could we use the colors of the orthoimagery in order to make topographic maps more realists? Could we adapt the symbolization of the roads depending on the color of an orthoimagery background in order to make them more readable? This issue invites us to first analyze the perception given by both representations and their role and use in geovisualization applications. How the world is perceived through topographic maps and orthoimages, which both aims at depicting the same landscape? Maps provide an abstract representation of the world, where features are categorized, selected, and represented with hierarchized and artificial symbols, and where additional information such as geographical names may be added. Orthoimages display all features that may be seen from the sky, with realistic or natural colors and textures, but without prior categorization, which may lead to misinterpretations. The role of the different spatial representations has also to be questioned. As long as maps were only available in paper format as the unique resource of spatial information, they were considered as the main way of storing spatial and geographical knowledge. With the emergence of present technologies, this knowledge has been stored in geographic databases. Maps thus become more adaptive to users’ needs and preferences. Moreover, maps are not any more designed has self sufficient representations but increasingly used to visualize complementary data. They could thus be adapted, faded or lightened in order to fulfill this usage. This evolution generates a “competition” between maps and orthoimagery data as background layers. One preliminary result is the use of orthoimagery patches instead of the green tint area widely used in topographic maps portraying vegetation. This first attempt should be improved weakening transitions from orthoimagery to map visualization, stylizing gradually textures from tint area to photorealistic patterns and adapting the symbolization of vector cartographic features to be better contrasted when overlaid to an orthoimage.

Résumé :	(auteur) Maps are used in various decision-making contexts, also where the influence of emotional responses to decision-making might be critical, such as under stress (i.e., real-time navigation using a mobile device, search and rescue missions, etc.), or due to varying user motivations (i.e., survival, boredom, leisure, fun, etc.). While cartographers and others have begun to systematically explore how display design, user background, and varying usage contexts might interact with spatiotemporal inference making, almost no research exists that investigates the role of human emotion in map-based decision making (Griffin and McQuoid, in press). In this paper, we propose a methodological extension to a previously suggested framework, aimed at quantitatively capturing the effect of emotion in human-map interactions (Fabrikant et al. 2012). Specifically, we propose to visualize human emotion captured in empirical map studies, for further systematic evaluation. Our promising preliminary results suggest that first, human emotions can be systematically captured using a skin conductance sensor coupled with the eye movement data collection method, and second, quantitative emotion data can be meaningfully analyzed to investigate aesthetic effects of display design decisions, specifically when coupled with other evaluation methods (i.e., questionnaires, etc.). We additionally demonstrate that human emotion measurements can be visualized, using standard cartographic depiction methods. With this contribution we hope to provide cartographers with a sound method to capture emotional and affective aspects of human-display interactions, specifically when empirically evaluating the aesthetic qualities of visual displays used for spatiotemporal inference making.

Résumé :	(auteur) The notion of cartographic style is identified as an essential element of map design in the cartographic literature, but is has not been systematically studied. (Kent & Vujakovic 2009) characterize style as “appearance and content”, dependent of the geographic space represented in the map. On the one hand, (Beconyte 2011) emphasizes the complexity to formally define the structure of the employed style, but on the other hand she also argues that “the concept of style is applicable to every type of maps” (p. 1). Both authors suggest that it is possible to distinguish different map styles, according to a set of quantifiable parameters or systematic criteria. (Christophe 2012) presents some potential approaches such as, visual categorization, map specification, and artistic design style characterization to systematically capture the notion of style. We contend that a specific map design method may produce cartographic results with typical visual characteristics that can be identified as a cartographic style. In this paper, we propose a systematic approach to formalize cartographic styles, to be able to identify and to automatically design maps based on a chosen cartographic style. We contend that a specified style may be applicable to any type of geographic data, and is thus able to create data independent so called stylized maps. Furthermore, we assume that the consistent application of stylistic rules may significantly improve the graphic quality of the resulting map, dependent also on users’ needs. We propose to formalize and implement stylistic rules with and for existing cartographic design tools. Our challenge consists in proposing a comprehensive design framework, taking also into account data preprocessing (ie, selection, generalization, etc.), the visual variables, legend design, and the geographic features to be mapped. Data-dependent styles, thus dependent on the displayed geographic features, may also be useful for style formalization. We aim at systematically specify and visually characterize topographic maps at the same scale (i.e., 1:25000), according to cartographic pre-processing, map legend design, and mapped feature types, but from two different mapping agencies, both with a long-standing mapping tradition (i.e., IGN France, and Swisstopo). We chose topographic maps for our research, because they are aimed at effectively depicting territorial complexity. The IGN and Swisstopo maps also illustrate different cartographic practices and resulting styles. This allows us to specifically evaluate the graphic composition of a topographic style and the resulting visual impact it may have on users’ map perception and cognition. We are currently also considering thematic maps, such as subway maps and ski trails maps, in order to obtain a broader understanding of cartographic styles. With this work, we hope to extract operational design knowledge such as, relevant criteria and parameters, to be able to design stylized maps, considering different cartographic practices for varying geographic areas.
