GEO is a partnership of more than 100 national governments and in excess of 100 Participating Organizations that envisions a future where decisions and actions for the benefit of humankind are informed by coordinated, comprehensive and sustained Earth observations.
Ministers of the GEO member governments meet periodically to provide the political mandate and overall strategic direction for GEO. The Mexico City Ministerial Declaration from the GEO Ministerial Meeting in 2015 saw world leaders commit to support open Earth observation data for the next decade. 104106 ParticipatingMember States Organizations Global Earth Observation System of Systems (GEOSS)
Together, the GEO community is creating a Global Earth Observation System of Systems (GEOSS). Earth observations from diverse sources, including satellite, airborne, in- situ platforms, and citizen observatories, when integrated together, provide powerful tools for understanding the past and present conditions of Earth systems, as well as the interplay between them. GEOSS aims to better integrate observing systems and share data by connecting existing infrastructures. There are more than 200 million open data resources in GEOSS from more than 150 national and regional providers such as NASA and ESA; international organizations such as WMO and the commercial sector such as Digital Globe.

Definition: Subset of the whole GEOSS resources defined by applying, via the DAB, a set of clauses Discovery clauses (e.g. spatial envelope, keywords, sources, etc.) Access clauses (e.g. data format, access protocol, CRS, etc.) Defined “View” exposed via the GEOSS Portal/APIs/Widgets/Mirror Sites
Consumer-defined View – i.e. Client-side These views are available only for the client application which defined the view. Provider-defined View –i.e. Server-side These views are available for all client applications. GEOSS Widget
A freely-available instantiation of selected GEOSS Portal widgets with various functionality made available for possible customization in various areas of application (e.g., a specific SBA, Initiatives, etc.).
• This is accomplished by publishing portal code parts (widgets) wrapped up in API
• Kernel at server side (continue maintenance, enhancements, etc., like a library) GEOSS Mirror
• GEOSS Portal site customisation for SBAs, Flagships, Initiatives, Communities It is available at www.geoportal.org/community/GEO_X_Initiative The customisation will better serve the specific community interests by filtering: • Catalogues and search results by a specific theme or GEOSS view (e.g., cold regions, mountains, etc.) • Location of interests • Services/Processing/Tools (in the future …) Thank you
