    Automated Production of Interactive 3D Temporal Geovisualizations so as to Enhance Flood Risk Awareness
    (The Eurographics Association, 2016) Jacquinod, Florence; Pedrinis, Frédéric; Edert, Jérémy; Gesquière, Gilles; Vincent Tourre and Filip Biljecki
    The FLOOD AR project originates from an explicitly expressed need for digital 3D temporal georeferenced models that can be largely diffused among riverside residents through computers and mobile devices, in order to support the raising of public awareness concerning flood risk along the Rhône river. This project is led by a multidisciplinary consortium of researchers from several fields who are working together to develop usable tools and models as well as recommendations regarding visual content, interfaces and context of use for those 3D models. As far as computer science is concerned, given the practical difficulties of resorting to 3D georeferenced technologies for practitioners and the current limitations of commonly used GIS data formats and tools, automatic tools allowing any interested parties to produce 3D temporal models in order to support flood risk awareness' enhancement were developed in the first phase of the project. The storage of those 3D models in an interoperable format (CityGML) ensures that those 3D temporal models are available for other purposes in relation to flood mitigation (regarding flood risk mitigation planning and public consultations or visual analysis for instance). Automating the production of 3D temporal models guarantees that those models can be produced for any territory along the Rhône river. A tool to visualize those 3D temporal models interactively will also be made available as an open source tool as part of the project.

    Visualization of Documented 3D Cities
    (The Eurographics Association, 2016) Chagnaud, Clément; Samuel, John; Servigne, Sylvie; Gesquière, Gilles; Vincent Tourre and Filip Biljecki
    Documents whether historical photographs or urban regulations are important for understanding the urban past as well as for urban planning. CityGML is an open standard used to represent 3D structure and thematic information of the cities. In this article, we briefly present how the recent extension to CityGML to represent documents has been integrated to the 4D virtual urban environment. We will then focus on different visualization techniques of documents in this environment and the various metrics used to evaluate them.
