• launched in response to calls for action by the 2002
World Summit on Sustainable Development, Earth
Observation Summits, and by the G8 (Group of
Eight) leading industrialized countries
• voluntary partnership of 99 governments and 87
international organizations
• provides a framework within which these partners
can develop new projects and coordinate their
strategies and investments
• charged with developing GEOSS
