The Camp Nou Stadium as a Testbed for City Physiology: A Modular Framework for Urban Digital Twins

Figure 1

Problem definition and identification of data layers. The definition of the case study determines the target layer, which is the Built Domain (last column). The real city (the physical twin) produces the data available for this simulation. The data belong to two of the nine layers that City Physiology identifies as the fundamental systems of a city: the Communication Network and the Built Domain, which is also the target layer. Data availability, on one side, and the aim of the case study, on the other, define which conceptual layers are available for simulation, as depicted in the 2nd and last column. In between them, the dashed lines represent the layers that will be defined in a 2nd step.
