Rationale for PDGS harmonization (2) In 2003 the EO Directorate approved a strategy forthe evolution of the several missions ground segments(handled and/or to be developed) into an open multimissionarchitecture, which included as main themes:• Adoption of a common architecture for all missions• Harmonization and standardization of interfaces• Evolution of current missions payload data ground segmentsinto the common architecture• Standardization of products and formats across missions• Re-utilization of already available and proven elements• Harmonization and rationalization of archives Implementation of the ESA proposed EO Long TermData Preservation (LTDP) strategy In line with the specific requirements for On-lineArchive Data Access
