QA4EO has been endorsed by CEOS as a contribution to facilitate the GEO vision for a Global Earth Observation System of systems(GEOSS). The aim of GEOSS is to deliver comprehensive and timely knowledge/information products worldwide to meet the needs of its nine "societal benefit areas". This can only be achieved through the synergistic use of data derived from a variety of sources (satellite, airborne and in situ ) and the coordination of the resources and efforts of the GEO members.
