TCS Satellite Data aims at implementing satellite Earth Observation (EO) services transverse to the large EPOS community and suitable to be used in several solid Earth science application scenarios.



Satellites are used in the Earth Observation domain to systematically monitor and widely analyse sea ice, the oceans, ground surface, and atmosphere.

The TCS Satellite Data aims at implementing and deploying robust Earth Observation services transversal to the large EPOS community and suitable for use in several solid Earth science application scenarios. These services have already well demonstrated their effectiveness and relevance in investigating the physical processes driving earthquakes, volcanic eruptions, and unrest episodes as well as those driving tectonics and Earth surface dynamics. They can therefore successfully contribute and foster advanced geophysical investigations.

In the first operational phase of the EPOS infrastructure, the TCS Satellite Data is mainly focused on radar techniques by benefiting from the Sentinel-1 constellation of the Copernicus Programme. For more than 25 years, radar images from space have been used to measure small displacements of the Earth surface related to earthquakes, landslides, and volcanic activity. These images are collected night and day under any and all weather conditions by using sensors mounted on board satellites orbiting at several hundred kilometres away from the Earth. The results of these measurements provide crucial information for a comprehensive and synoptic understanding of ground deformation phenomena and their trigger events.

Since the services will include both access to data and processing utilities, we have to consider two specific functioning modes:

  • Continuous mode, systematic and periodic generation of products (for example the systematic production of updated time series of surface deformation over a given defined area)
  • On demand mode, users run the tools and process the chosen satellite dataset (for example ad hoc generation of deformation measurements using diachronic satellite observations during a telluric crisis, e.g. a co-seismic terrain motion map).

The TCS partners provide products and services but they are not the owner of the input data (satellite images) that come from National and International space agencies. Two space agencies are currently involved as associated members, CNES (France) and European Space Agency (ESA). One of the main TCS objectives for the future activities is to broaden the base of national space agencies that actively contribute to the TCS.

The TCS is also working to have a common interface to access the TCS products and services. To this aim, European Space Agency is contributing to the TCS with the Geohazards Thematic Exploitation Platform or GEP, a cloud-based user-driven environment specifically designed for the advanced exploitation of EO data. The GEP is using cloud processing facilities to enable both systematic and on-demand services.
