Discovery and Access

The WGISS Connected Assets System Level Team is committed to enabling discovery and access of EO satellite data.

WGISS Connected Assets System integrates the CEOS Agencies’ data collections which 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.

The IDN webpage provides information about the collection metadata and how to connect to it.The CWIC and FedEO webpages provide How-To Guides — to connect as a client partner or data partner.

Discovery and Access of satellite data is possible using:

  • the International Directory Network (IDN) – The CEOS IDN Master Directory assists researchers by providing free, online access to information on scientific datasets (metadata)  in the Earth sciences, including geoscience, hydrospheric science, biospheric science, satellite remote sensing, and atmospheric science. This metadata describes data held by university departments, government agencies, multinational organizations, and other organizations all over the world.
  • the CEOS WGISS Integrated Catalog (CWIC) – The CWIC Project provides the world’s satellite Earth observation data providers with a way to make their data collections and individual granules searchable using common standards.
  • the Federated Earth Observation 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. 
  • CEOS OpenSearch – CEOS OpenSearch is a collection of simple formats for the sharing of search results using a common set of CEOS interoperability best practices in order to allow for standardized and harmonized access to metadata and data of CEOS agencies, including CWIC and FedEO communities.

New Dataset Availability Alert: JERS-1 

ESA has announced that the JERS-1 Optical and Synthetic Aperture Radar Level-1 products are now available to download. According to the ESA announcement:

“These data are free of charge and access is granted immediately to all users worldwide after fast registration.

These data represent the result of a systematic reprocessing project of the entire ESA JERS-1 data holdings. The JERS-1 SAR data are available in CEOS format as Precision Image (PRI) and Single Look Complex Image (SLC)products. Whereas, the JERS-1 OPS data are available in GeoTIFF format and represent System Corrected products (SYC) from the VNIR optical sensor… [ read more ].
