The GeoVIS team provides geovisualization knowledge, methods and tools allowing various users to design graphic representations of spatio-temporal phenomena, and to infer spatio-temporal knowledge from the interaction with some dimensions of a phenomenon, based on spatial data (maps, imagery, 3D models, DTM, point clouds, etc.) and external data (texts, photographies, web data, thematic data, etc.). The heterogeneity (source, scale, content, precision, dimension, temporality) and the imprecision of these data and represented phenomena imply to address geovisualization issues encompasses cartography, GIS, InfoVis, HCI, computer graphics and image processing.
L'équipe fournit des connaissances formalisées, méthodes et outils de géovisualisation permettant à des utilisateurs variés, de concevoir des représentations graphiques de phénomènes spatio-temporels, sur lesquelles raisonner spatialement et temporellement, en leur permettant d'interagir avec une ou plusieurs dimensions du phénomène, à partir de données géographiques (cartes, imagerie, modèles 3D, modèles numériques de terrain, nuages de points, etc.) et de données externes spatialisées (textes, photographies, données du web, données thématiques, etc.). L’hétérogénéité (source, échelle, contenu, précision, dimension, temporalité) et l'imprécision de ces données comme des phénomènes représentés, impliquent de résoudre des problématiques de géovisualisation, en particulier cartographie, SIG, Visualisation d'Informations, Interaction Homme-Machine, informatique graphique et traitement d'images.
Visualization. Visual integration and complexity, abstraction and level of detail (generalization, symbolization), graphic representation (graphic semiology, style).
Visualisation. Intégration et complexité visuelle, abstraction et gestion du niveau de détail (généralisation, symbolisation), représentation graphique (sémiologie graphique, style).
Interaction. Interaction between the users and the visualization, according to the support and use context, the users' tasks, and the visual characteristics or the specific spatial phenomena of study: interaction techniques and models, data and representations continuums, and also analysis and learning from interaction activities and traces.
Interaction. Interaction entre l'utilisateur et la visualisation, en fonction du support et du contexte d’utilisation, des tâches de l'utilisateur, et des caractéristiques visuelles ou phénomènes spatialisés à étudier : techniques et modalités d’interaction, continuums de données et de représentations, analyse et apprentissage à partir des traces d’interaction.
Spatial Immersion. Immersion through devices facilitating visual, tactile and sensitive perception, and the design of geographical spaces: virtual, augmented and mixed realities, tactile maps.
Immersion spatiale. via des dispositifs facilitant la perception visuelle, tactile et sensorielle, et le design des espaces géographiques : réalités virtuelle, augmentée et mixte, cartes tactiles.
Graphic rendering. Improvement of the physical rendering of images, geometric and radiometric analysis, web diffusion of massive data, and real-time 3D rendering.
Rendu Graphique. Amélioration du rendu physique des images, analyse géométrique et radiométrique, diffusion web de données massives, rendu 3D temps réel.
User experience (UX). Visual tests, surveys, and prototypes.
Expérimentation utilisateur (UX). Tests visuels, enquêtes, prototypage.
Spatial data processing for visualisation. Spatial analysis, data enrichment, pattern recognition, multiple representation.
Traitement de données spatiales pour la visualisation. Analyse spatiale, enrichissement de données, reconnaissance de formes, représentation multiple.
