                Data Policies

• WMO Resolutions 40 and 25 include
  free sharing of "essential data" while
  respecting all other data policies of
  WMO Members
• WIS is designed with mechanisms
  for authorization and authentication to
  support data policies and to ensure the
  integrity of data discovery and delivery

Need for a Mature, Sustainable Infrastructure
 "In situ observation infrastructures should ideally
 be organized on the basis of the existing and mature
 measurement infrastructures for which observational
 techniques, agreed standards and protocols are available.
 The main critical issue regarding these observational data
 is the sustainability of its infrastructure including the
 supporting networks."
 "At international level, a number of highly evolved
 monitoring networks exist and operate strong procedures
 of standardisation, archiving, reporting and system
 maintenance. Meteorological monitoring undoubtedly
 represents the most advanced of these, and sets a
 standard to which other systems at present can only
 aspire."
     Quotes from "Global component of the GMES Land Monitoring
     Core Service", Draft v.02 (GMES Global Land Working Group)

         Conclusion
• WIS operational real-time
  infrastructure could be useful
  to the GMES Core Services
• Discovery functions of GMES
  Core Services could leverage
  the WIS DAR catalog facility
• GMES centres could partner
  with WIS NCs and DCPCs
