USGS CEOS Activities
CEOS Working Groups, Virtual Constellations, and Ad Hoc Teams
The original function of CEOS was to coordinate and harmonize Earth observations to make it easier for the user community to access and use data. CEOS initially focused on interoperability, common data formats, the inter-calibration of instruments, and common validation and inter-comparison of products. CEOS now focuses on validated requirements levied by external organizations, works closely with other satellite coordinating bodies and continues its role as the primary forum for international coordination of space-based Earth observations.
The CEOS Working Groups and Virtual Constellations coordinate the assets of CEOS Agencies to accomplish these objectives and deliverables. The five CEOS Working Groups address topics such as calibration/validation, data portals, capacity building, disaster management, climate, and common data processing standards shared across a wide range of Earth observation domains. In support of the GEO objectives and as the space component of the GEOSS, CEOS has developed the concept of virtual, space-based Constellations. A Virtual Constellation is a coordinated set of space and/or ground segment capabilities from different partners that focuses on observing a particular parameter or set of parameters of the Earth system. CEOS also has the ability to create an Ad Hoc Team in the event that permanent mechanisms (Working Groups and Virtual Constellations) are insufficient for CEOS to undertake a particular activity.
USGS is presently active in the following Working Groups,Virtual Constellations and Ad Hoc Teams.
