The various instruments and systems comprising GEOSS need to be configured so that they can exchange information with one another and provide the integrated data and information products that decision makers need.
The compatibility of different types of data and systems will be ensured by the emerging “architecture” of GEOSS. Architecture refers to the arrangements for making all of the GEOSS components “interoperable”.
These components include numerous in-situ, airborne and space-based Earth observation systems; data-assimilation centres for collecting and processing the raw data needed by modellers and researchers; computerized models of the oceans, atmosphere and other Earth systems; systems and services for distributing data; and decision-support tools and other products for end-users.
The components, services and standards that together constitute GEOSS will be described in a registry. This essential part of the GEOSS architecture will feature tools for browsing through its contents.
The GEO Secretariat Expert responsible for Data Management is Osamu Ochiai.
