A DTC is a virtual representation (or replica) of a Physical System (PS) within its environment. The DTC is continuously updated with real-time data throughout its lifecycle and, at the same time, can interact with and influence the PS. The PS produces data related to the system. The DTC takes as input such data and uses a set of models to carry on different operations and actions on the PS. The proposed DTC is structured with a set of data and models associated with the Geo-Physical System (GeoPS), able to make available a set of services corresponding to the functions of the DTC. The identified requirements have addressed the selection of the data used as input to the DTC. The data contain the information and can be simply classified in:
● EO data, like SAR satellite measurements, multi- and hyper-spectral measurements of
atmospheric parameters, data obtained from integration;
● Ground data detected from seismic and geodetic networks;
● Ancillary data, like DEM, hazard maps, vulnerability data.
