CEOS Development Environment

Federated EO Gateway (FedEO)


FedEO (Federated Earth Observation missions access) provides a unique entry point to a growing number of scientific catalogues and services for, but not limited to, EO European and Canadian missions.  FedEO is deployed with ESA (European Space Agency) infrastructure as a gateway to:

  • Provide brokered discovery, access and ordering capability to European/Canadian EO missions data based on HMA (Heterogeneous Missions Accessibility) interfaces;
  • Implement the OpenSearch OGC (Open Geospatial Consortium) and other interfaces for an increased number of discoverable and accessible EO data collections;
  • Implement the OpenSearch OGC interfaces for interfacing with CEOS Community Catalogues and Clients.

FedEO was initially developed as a prototype for GEO/GEOSS (Group on Earth Observations/Global Earth Observation System of Systems) and for EO-DAIL (Earth Observation Data Access & Integration Layer).  It was consolidated after the CEOS Plenary in 2012 to facilitate access to European missions data in the international context and primarily in CEOS.
