A DTC is a virtual representation (or replica) of a Physical System within its environment. The DTC is suitable to be continuously updated with real-time data throughout its lifecycle and, at the same time, can interact with and influence the Physical System itself. The Physical System produces data and the DTC takes as input such data and uses a set of models to carry out different tasks. The Geohazard DTC proposed by GET-it is structured with a set of services exploiting several data types and models associated with the Geo-Physical System. Data can be classified in:
- EO data, e.g., SAR satellite measurements (ground changes and deformation), multi- and hyper-spectral measurements (atmospheric parameters), and related products obtained from integration;
- Ground data detected from seismic and geodetic networks, and related products obtained from integration with satellite data;
- Ancillary data, like DEM, hazard maps, vulnerability data.
Multisource and multiparametric datasets (Level 1) are integrated to obtain added value Geohazards Early DTC products (Level 2). Then, model components (Level 3) can reflect the Geo-Physical System and its environment (its actual and past state), enhancing the understanding and enabling the analysis, and can be used to predict information not yet measured, allowing decision making and trade off analysis.
In the conceptual workflow the Geohazard DTC is split in four blocks:
- Input data, either from EO or from ground networks, possibly correlated by ancillary data;
- Geohazard DTC core, containing the modules for generating the proposed products. A hierarchical ontology is applied, where product complexity ranges from Level 1 to Level 2 to Level 3;
- Output services (risk analysis, what-if scenarios);
- The stakeholders link to stakeholders involved.
Conceptual workflow of the Geohazard DTC
The Geohazard DTC core is composed of ten building blocks or modules, taken from the most advanced scientific and technological achievements in the field of geohazard analysis and assessment. They are discussed in detail in [hyperlink to modules], along with their interconnections and dependencies.
