The Committee on Earth Observation Satellites (CEOS) was established in 1984 in response to a recommendation from the
Economic Summit of Industrialized Nations Working Group on Growth, Technology, and Employment's Panel of Experts on Satellite
Remote Sensing. CEOS participants are Members, who are national or international governmental organizations who operate
civil spaceborne Earth observation satellites, and Associates who are governmental organizations with civil space programs in
development or international scientific or governmental bodies who have an interest in and support CEOS objectives. The
primary objective of CEOS is to optimize benefits of satellite Earth observations through cooperation of its participants in
mission planning and in development of compatible data products, formats, services, applications and policies.
To pursue its objectives, CEOS establishes working groups and associated subgroups that focus on relevant areas of interest.
While the structure of CEOS has evolved over its lifetime, today there are three permanent working groups. One is the
Working Group on Calibration and Validation that addresses sensor-specific calibration and validation and geophysical
parameter validation. A second is the Working Group on Education, Training, and Capacity Building that facilitates
activities that enhance international education and training in Earth observation techniques, data analysis, interpretation
and applications, with a particular focus on developing countries. The third permanent working group is the Working Group on
Information Systems and Services (WGISS). The purpose of WGISS is to promote collaboration in the development of the
systems and services based on international standards that manage and supply the Earth observation data and information from
participating agencies' missions.
WGISS places great emphasis on the use of demonstration projects involving user groups to solve the critical interoperability
issues associated with the achievement of global services and its structure reflects that objective. The Technology and
Services Subgroup initiates tasks to explore emerging technologies that can be employed to create data and information
systems and to develop interoperable services. The interests of the subgroup span the full range of the information
processing chain from the initial ingestion of satellite data into archives through to the incorporation of derived
information into end-user applications. The subgroup has overseen the creation of an Interoperable Directory Network and an
Interoperable Catalog System and has tasks that are investigating the use of new technologies such as Web Services, Grid, and
Open Geographical Information Systems to provide enhanced capabilities.
The WGISS Projects and Applications Subgroup works with outside organizations to understand their requirements and then helps
them to exploit the tools and services available through WGISS and its members and associates. WGISS has instituted the
concept of a WGISS Test Facility to test and develop information systems and services prototypes collaboratively with these
organizations to meet their specific requirements. This approach has the dual benefit of addressing real information systems
and services needs of science and applications projects and helping WGISS to expand and improve its capabilities based on
the experience and lessons learned from working with the projects.
