EGMS provides consistent, regular, standardised, harmonised and reliable information regarding natural and anthropogenic ground motion phenomena over the Copernicus Participating States and across national borders, with millimetre accuracy. This layer is produced based on GNSS data from various sources, with the EUREF Densification network as the main entry point. After filtering and quality control, a total of 3770 stations are used to generate the GNSS model which contains average velocities in east, north and up directions displayed on a 50-km grid. The grid dimension is determined by the average distance between well-maintained GNSS stations over continental Europe. The GNSS model is distributed to users in a single comma-separated values file. Each cell of the model is associated to a value of vertical and horizontal velocity. The product covers the Copernicus Participating States (except for DROMs) and United Kingdom.

Within the Copernicus component, a portfolio of land monitoring activities has been delegated by the European Union to the European Environment Agency (EEA) and the DG Joint Research Centre of the European Commission. The Copernicus land monitoring products and services are made available on a principle of full, open and free access, as established by the Commission Delegated Regulation (EU) No 1159/2013 of 12 July 2013. Free, full and open access to the products and services of the Copernicus Land Monitoring Service is made on the conditions that: 1. When distributing or communicating Copernicus Land Monitoring Service products and services (data, software scripts, web services, user and methodological documentation and similar) to the public, users shall inform the public of the source of these products and services. 2. Where the Copernicus Land Monitoring Service products and services have been adapted or modified by the user, the user shall clearly state this. 3. Users shall make sure not to convey the impression to the public that the user's activities are officially endorsed by the European Union. d92e61be-d6e8-4bc1-aa10-f742bf27bab9 vector 50 utf8 geoscientificInformation -31.30 44.86 27.60 71.21 2015-02-01 2023-01-01 ascii (.csv, .txt, .sql) https://land.copernicus.eu/en/products/european-ground-motion-service WWW:LINK Product Information & Technical Documentation https://land.copernicus.eu/en/products/european-ground-motion-service/egms-gnssmodel#download WWW:DOWNLOAD CLMS Website Download https://doi.org/10.2909/8780c353-e01e-4b51-bbb3-e1e01a597033 DOI https://doi.org/10.2909/8780c353-e01e-4b51-bbb3-e1e01a597033 Commission Regulation (EU) No 1089/2010 of 23 November 2010 implementing Directive 2007/2/EC of the European Parliament and of the Council as regards interoperability of spatial data sets and services 2010-12-08 publication See the referenced specification The GNSS model is obtained from the analysis of 3770 GNSS stations mainly part of the EUREF Densification network. The stations were selected based on the following criteria: i) minimum length of time series >3 years, ii) stations should not record time series with artificial artifacts and iii) stations should not record strong non-linear motion except for seasonality. The GNSS model is then derived following the least-squares collocation concept. The principle behind this approach is to use the correlations of GNSS station velocities to predict new values at any new point within the covered area, together with associated uncertainties.
