Analysis tools: The last point that interests us for short-term.The city representation is completed in our work by media that may provide It takes place in a third-party application or in a web browser. This point is also related to the problems of data visualization, whether We want to deduce these views from the initial model in an automatic way. With the data according to the concerned need. Our research focus consists in modifying the geometry and semantics associated That a model dedicated to tourism application. Required for a simulation process of water flow.Ī 3D model proposed to an urban planner will not possess the same elements The model imported into a noise simulation is not necessarily the same as the one Possibility of providing a “dedicated view” to the researchers or practitioners we meet. Modes of representation for cities: This third point concerns the.Managing the evolution of the city during time is targeted and some solutions are To manage the evolution of city objects (buildings, vegetation, urban furniture, land). We are currently working on amendments proposals for standards in order Years in 2D but needs to be studied in a normative context for 3D. City Evolution: This second aspect has already been covered for many. Of the standard concerning, for example, sensors, coverages, or vector data. In our work, we often look at 3D data but we also follow the development We participate in the creation of standards of the In our research, we are positioned in the context of interoperability Of heterogeneous data to fulfill the demands of experts. Agglomeration of data: The first issue concerns the agglomeration.The use of these data leads us to look at several scientific bottlenecks: The standardization processes in which we are involved, for example within consortia such as the Open Geospatial Consortium (OGC), enable the creation of new standards. The processes that we propose to consider are based on spatio-temporal, but also thematic dimensions and should allow promoting the exchange of data in an interoperable way. It often refers to the time and space in which it will evolve (rapidly with sensor data, but also over long periods of time with the evolution of city buildings, for example). The data is geometric (generally 3D) and has related semantics and topology. This theme, anchored between geometric modeling and geomatics, leads us to propose new data processing algorithms, to allow a better understanding of the territory, but also of its evolutions. In recent years, our project has therefore focused on modes of representation and the dynamics of the city. Vcity Team’s research activity is anchored in the field of geometric modeling and data science, with an approach that has often led us to collaborate with various disciplines (astrophysicists, paleoanthropologists, historians, urban planners, geographers, etc.).
