The Working Group on Information Systems and Services (WGISS) promotes collaboration in the development of systems and services that manage and supply Earth observation data. WGISS addresses the internal management of EO data, the creation of information systems and the delivery of interoperable services. The activities and expertise of WGISS span the full range of the information life cycle from the requirements and metadata definition for the initial ingestion of satellite data into archives through to the incorporation of derived information into end-user applications.
