The Committee on Earth Observation Satellites (CEOS), an
international framework for coordinating all spaceborne
Earth observation missions, has established a "Purge Alert"
service to help to ensure the long-term preservation of valuable
Earth observation data. We encourage you to participate in this
initiative that enables data archive managers to: 1) advise other
archives of Earth observation data holdings scheduled to be
destroyed, and 2) offer these data to other archive centers.
We realize that it is the responsibility of all agencies holding
data to assess the relative value of their holdings and their
requirements for long-term maintenance of those holdings.
Sometimes an agency must make the decision to purge data that
could be important to help meet the mission requirements of another
agency. The CEOS Working Group on Information Systems and Services
(WGISS) finds that in this
continuing process of assessment, it is helpful to share our
information and findings with other data managers before data
are purged. Thus, as a community, we can make wiser decisions
about purging and transferring archival data.
