CEOS used to be verified less than the auspices of the industrial Summit of Industrialized international locations in 1984 in keeping with a advice from a panel of specialists in distant sensing in the operating staff on progress, expertise and Employment (CEOS, 2009). The panel famous the collective worth of the world’s Earth distant sensing functions and the benefits that may be won by means of the coordination of civil Earth watching satellite tv for pc missions. via cooperating in venture making plans and the improvement of appropriate information items, functions, companies and rules, the nationwide area courses could maximize the bene?ts in their person inve- ments and have the capacity to higher handle the environmental demanding situations of the full overseas group. CEOS used to be to function the focus for this inter- tional coordination and to supply the discussion board for the swap of coverage and technical details. The participants of CEOS are governmental corporations which are overseas or nationwide in nature and are accountable for a civil space-borne Earth statement software that's presently in operation or in a sophisticated level of procedure devel- ment. CEOS additionally has verified affiliate participants which are comparable governmental corporations with a civil space-segment task in an early level of method dev- opment or people with a signi?cant ground-segment job that helps CEOS ambitions. affiliate contributors can also be present satellite tv for pc coordination staff and scienti?c or governmental our bodies which are foreign in nature and feature a signi?cant programmatic task that likewise is aligned with the pursuits of CEOS.

In the case of the NASA CEOP Satellite Data Server, the user input for the project revealed several challenges not normally faced by WCS servers. A key revelation was the expectation that many of the users in question were likely to want to analyze long time series of data for very small geographic areas. ) This in turn raised a number of challenges that rippled throughout many aspects of the project, including the WCS server design and implementation. Finally, user 3 Data Integration Support to the CEOP Project 35 questions about the content of what they were actually seeing pointed out the need to consider quality screening and provenance in the WCS server.

Because the Hyrax server maintenance is supported by the OPeNDAP, Inc, a non-profit organization, implementing the key gateway functionality as a “format handler” in Hyrax allows this capability to live long after the ACCESS funding for the NASA activities. It is hoped that CEOP and other science and applications programs with similar data analysis requirements will be able to benefit from both the WTF-CEOP lessons learned and the data integration services it has advanced.
