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.

[Vedettes matières IGN] GénéralisationRésumé : (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.

[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.
