Six months after the first EGMS’ Ortho products release, the ORIGINAL consortium, of which TRE Altamira is a proud member, is delighted to announce that all products are now available for visualization and download by the general public.

For those who don’t know, EGMS is an EU Copernicus Land Monitoring Service (CLMS) program providing continental-scale monitoring of European ground deformation. Based on data from the Sentinel-1 radar satellite constellation, EGMS delivers millimeter-scale ground and structural displacement measurements across the entire European continent, to better understand and mitigate the risk posed by geological hazards.

The image shows an example of ground motion in the surroundings of the River Thames, London (UK). Red areas are identified as the ones affected by a higher level of displacement. Data are from EGMS Ortho products, showing the vertical component of motion (2015-2020).
The image shows an example of ground motion Corta Atalaya mine in Andalusia, Spain. Red areas are identified as the ones affected by a higher level of displacement. Data are from EGMS Ortho products, showing the vertical component of motion (2015-2020).

The data available cover the period from February 2014 to December 2020, and include all three levels of the EGMS product:

  • Basic: Line of sight velocity maps in ascending and descending orbits, with annotated geolocalisation and quality measures per measurement point;
  • Calibrated: Line of sight velocity maps in ascending and descending orbits, referenced to a model derived from the time-series data from global navigation satellite systems;
  • Ortho: Components of motion (horizontal and vertical) anchored to the reference geodetic model. Ortho products are resampled to a 100 m grid.

Users can freely visualize and interrogate the data on the Copernicus portal. To download them, it is necessary to create a free EU account.

You can consult the Product User Manual for guidance on how to use the products, and the Product Description and Format Specification document to better understand the product details.

EGMS is Framework Service Contract by the European Environment Agency (EEA). It is run by the ORIGINAL consortium, combining the interferometric radar expertise of the main partners: e-GEOS, the Norwegian Research Centre (NORCE), the Italian company TRE Altamira, and the German service provider company GAF, supported by the German Aerospace Center (DLR), the Geological Survey of Norway, the Dutch company PPO.labs, the Hungarian Satellite Geodetic Observatory (SGO), the British Earth Metrics, and by the Italian company Nhazca, a spin-off of the Sapienza University of Rome.
