BREAKING NEWS 2019
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 of represented phenomena imply to address the following issues:
The GeoVIS team contributes in geovisualization, which encompasses cartography, GIS, InfoVis, computer graphics and image processing fields of study.
- Visualization : visual integration and complexity, abstraction and level of detail (generalization, symbolization), graphic representation (graphic semiology, style).
- 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.
- Spatial Immersion, through devices facilitating visual, tactile and sensitive perception, and the design of geographical spaces: virtual, augmented and mixed realities, tactile maps.
- Graphic rendering: improvement of the physical rendering of images, geometric and radiometric analysis, web diffusion of massive data, and real-time 3D rendering.
- User experience (UX): visual tests, surveys, and prototypes.
