Objectives

The overarching objective of the EO Data Archiving Service (EODAS) is:

  1. 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)
  1. to provide/deliver the data in scope of the Service back to ESA (or other recipients) upon request.

 

Services

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.
