Applications based on EGMS products: A review

The European Ground Motion Service (EGMS) represents the largest wide area Persistent Scatterer Interferometry service ever conceived. It is part of the Copernicus Land Monitoring Service's product portfolio. Thanks to its technical characteristics, and the fact that EGMS products are made available on a full, open, and free-access principle, the EGMS has the potential to become a game changer in the way ground motion data are used in Europe. Three years after the publication of the first EGMS products, this initial review studies the scope and impact of this service in terms of applications. After a brief introduction to the service, the paper describes the main EGMS trends, including the procedures to analyse and exploit its data, and a review of its main applications. The quantity and quality of the applications are useful ways to show the potential of the service. This can open the door to a future widespread use of EGMS data. Next, the paper features a technical discussion on the main characteristics of the EGMS products, the main EGMS validation activities, and future research lines.
