Progress in the field of large-scale data acquisition as well as cost reductions have allowed many cities to have their “digital double”. This is the case of the city of Lyon (France), which has at its disposal more than 540 Km² of data. 3D models are used by decision-maker in many fields ranging for example from urban planning to the simulation of physical phenomena (noise propagation, flood simulation …). Innovative new tools can also be designed with these data. This is for example the role of TUBA or the An Augmented third location that seeks to bring out new applications made possible thanks to these data. In this context, the data must be aggregated, prepared for a particular use (eg related to a simulation of physical phenomenon) and then visualized. The use of these data leads us to look at several scientific bottlenecks:
The scientific obstacles discussed above can only be addressed if we provide tools to access, edit, and visualize 3D data of the city. These tools are lacking in many laboratories we work with, which are from the field of Communication Science or Social Science. It is in this context that the Virtual City project was born thanks to funding:
Since 2012, we strive to develop a solid software foundation supporting today several research projects, which will be detailed on this website.
