RESEARCH Project- Managing temporal change of cities

An increasing number of cities are developing digital models. It becomes thus necessary to take into account changes over time. In this project, we would like to use standards to take into account these changes. A first approach is to propose modification in cityGML attributes in order to add temporal informations. In this first step, we have proposed a new method in [Morel, 2014]. This method is efficient for any kind of changes of the city objects (semantic, geometry, topology or appearance). We then propose an extension of our method in order to consider more frequent changes as it is the case with sensors data that can be linked with part of city objects.
