Presentation in Data Week 2021. The main objective of this workshop is to bring together four pioneer H2020 projects that are at the frontier of European research and innovation and are developing Artificial Intelligence and Big Data technologies for Copernicus data. These projects are ExtremeEarth (http://earthanalytics.eu/), AI4Copernicus (https://ai4copernicus-project.eu/), DeepCube (https://deepcube-h2020.eu/) and CALLISTO (https://callisto-h2020.eu/). The first two of the projects have been funded by ICT calls while the other two have been funded by DT-SPACE calls.
