The intergovernmental Group on Earth Observations (GEO) is leading a worldwide effort to build a Global Earth Observation System of Systems (GEOSS). GEOSS builds upon, and adds value to, functioning  Earth observation systems by supporting their interoperability, among other objectives.  The added value primarily comes from interoperability facilitating the creation of datasets from disparate observation systems that can be used to obtain vital information for the benefit of society.

Interoperability in GEOSS will be achieved primarily by specifying how GEOSS components exchange data and information at their interfaces. The GEOSS strategy is to realize a system of systems through adoption of selected international standards that enable interoperability.

Central to these goals is the maintenance of various databases describing GEOSS components and their interfaces, and the standards, protocols and other specifications enabling interoperability between them.
