In Brussels, ministers from around the world are expected to endorse the Group on Earth Observations’ much-anticipated 10-year Implementation Plan for the creation of a ‘Global Earth Observation System of Systems’ (GEOSS). According to EC Research Director-General and GEO Co-Chair Achilleas Mitsos, preparation of the Implementation Plan meant sticking to a tight schedule. Based on its ‘Framework Document’, the GEO started work on the plan less than a year ago, in early 2004, prior to the second Earth Observation Summit in Tokyo.
