2 Group on Earth Observation and Global Earth Observation system of systems GEO AND

3 The Group on Earth Observation (GEO) 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.

4 Participating Member States Organizations

5 Global Earth Observation System of Systems () Together, the GEO community is creating a Global Earth Observation System of Systems (). Earth observations from diverse sources, including satellite, airborne, insitu 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. aims to better integrate observing systems and share data by connecting existing infrastructures. There are more than 200 million open data resources in 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.

15 Portal User-centric, considering various user communities: GEO Flagships and Global initiatives ESA Thematic Exploitation Platforms SBA/Thematic Customization: Satellite: includes smart filters for imagery (Landsat, Sentinel 2) and SAR-type (Sentinel 1) satellite data; Disater Resilience SBA: Earthquake events filters

16 Platform Re-usable Components SUPPORTING USER COMMUNITIES

17 APIs DOWNSTREAM MIDSTREAM end Users A set of standard Web service interfaces: e.g. OGC service interfaces, OAI-PMH, FTP, etc. A set of APIs for software developers: Client side APIs: (high-level) JavaScript library. (Python) Server side APIs: REST/JSON APIs OpenSearch APIs. Applications Applications Applications Application Developers (intermediate Users) Common Infrastructure APIs Mediation modules Portal Advanced users who are experienced in the utilization of geospatial data Web developers with good knowledge of W3C technologies, including: HTML5, Javascript, and CSS Expert users in developing applications which communicate with remote servers over HTTP

18 View Definition: Subset of the whole 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 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.

19 Widget A freely-available instantiation of selected 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)

20 Mirror Portal site customisation for SBAs, Flagships, Initiatives, Communities It is available at The customisation will better serve the specific community interests by filtering: Catalogues and search results by a specific theme or view (e.g., cold regions, mountains, etc.) Location of interests Services/Processing/Tools (in the future )
