Nathalie Stéphenne gave a joint presentation with Christian Barbier from the Liège Space Center at the NEREUS/ ESA symposium organized by BavAIRia. This symposium is the last in a trilogy of conferences answering the question: What can Sentinel data do for the regions? The presentation was entitled “Land motion monitoring in Wallonia”, and set out an action plan to achieve a better match between the needs of administrations and the opportunities offered by Europe’s Copernicus space program.
