The overarching objective of the EO Data Archiving Service (EODAS) is:
- to provide a secure and reliable archive of ESA’s Earth Observation data covering historical, present and future ESA missions as well as Third Party missions
- ESA missions (ERS, ENVISAT, Earth Explorers);
- ESA Third Party Missions (eg Landsat, ALOS, etc.);
- Historical, present and future missions (Sentinels missions are excluded)
- to provide/deliver the data in scope of the Service back to ESA (or other recipients) upon request.
The two main services proposed by the EODAS are:
The Data Archival service
This service consists in providing a reliable archive of ESA’s Earth Observation data, covering historical, present and future ESA and Third Party missions:
- safely archiving of the data in two physical copies in physical sites remote from one another;
- maintaining and executing the various archive operational procedures, including for the continuous alignment of the central and redundancy copies of the data;
- keeping the archival infrastructure in line with constructor recommendations, including any updates and media migration;
- producing reports on the status and contents of the archive.
The Data bulk‐extraction and delivery service
This Service consists in providing/delivering the data in scope of the Service together with accompanying metadata and mission documentation back to ESA (or other recipients) upon request.
- reception and acknowledgement of the request for data;
- identification and extraction from the archive of the required data;
- delivery of the data, on media or on‐line;
- verification of the data delivery activities and the reporting to the ESA Service Manager;
- logging of the delivery in the Data Management System;
- monthly and upon request production of a data delivery report.
