The IEEE Committee on Earth Observation (ICEO) facilitates broad-based IEEE participation in the Group on Earth Observations (GEO) and its international effort to create a Global Earth Observation System of Systems (GEOSS) for applying Earth observation data and information for societal benefits. The focus of GEO and ICEO is helping to improve living conditions, particularly in developing countries, through the development of GEOSS, a realizable global resource for decision makers at all levels. To support this development, GEOSS requires the broad range of skills embodied in the IEEE membership from System of Systems (SoS) engineering and communication to standards and information applications.
