The Data Terra EOSC Node is a thematic node for Earth and Environemental resources. Its Resource Catalogue gathers in one place the datasets, publications, softwares, services and semantic artefacts published at the French and German levels. Researchers can search all of them at once, narrow the results by scientific theme, place and time, and follow a direct link to the repository that holds the resources. The catalogue does not host resources itself: it describes what exists, keeps those descriptions current by harvesting periodically its sources, and hands the user over to the provider for access.
