Connected Data Assets

This page contains details about the CEOS Agencies’ data collections that are connected via the supported WGISS standards – OGC CSW 2.0.2 and CEOS OpenSearch Best Practices – which allow independent clients to search and access their unrestricted data.

Each system link listed below will provide information about which collections and how many granules the system connects to. These metrics will be updated regularly, as often as monthly.

A data collection consists of the data records of one mission, sensor, and product type and the associated knowledge. It is an ensemble of some products/granules having a common focus or theme or purpose and is generally located at a single Data Partner.

A data granule is the smallest aggregation of data which is independently managed (i.e. described, inventoried). A data collection can consist of many granules.

CMR Earthdata Access Holdings metrics for NASA EOSDIS, IDN, and CWIC

Earthdata Access Holdings page provides easy-to-use access to NASA’s Earth Observing System Data and Information System (EOSDIS), International Directory Network (IDN), and CEOS WGISS Integrated Catalog (CWIC) metrics of all providers’ collections and granules metrics. Also, the user can generate list of the providers’ collections with associated granule metrics and links to the collection metadata landing pages. All the metrics on the page make-up the overall IDN metric counts.

FedEO metrics

FedEO (Federated Earth Observation Gateway) provides brokered collection discovery, granule discovery, access, and ordering capabilities to mainly European & Canadian EO missions data based on HMA (Heterogeneous Missions Accessibility) and OGC (Open Geospatial Consortium) standard interfaces. It implements the OGC OpenSearch and CEOS OpenSearch Best Practices (and other) interfaces for an increasing number of discoverable and accessible EO data collections and for interfacing with CEOS and other international Community Catalogues and Clients. The FedEO metrics page contains downloadable information about the data collections and the number of granules per collection that are accessible via FedEO and FedEO maintains a live asset status page at
