Standards and Requirements
The Airborne Mission Data System Requirements and Satellite Mission Data Requirements from NASA Headquarter's Earth Science Division include Mission Requirements from NASA's Earth Science Data and Information System (ESDIS) Project as well as the approved list of standards shown below. These Mission Requirements are managed through the ESDIS configuration control process involving review and comments from all affected organizations. Additional standards and conventions approved for use in NASA Earth science data systems are managed by NASA's ESDIS Standards Office (ESO). ESDIS Mission Requirements include:
- ISO 19115 Geographic Information Metadata Standard
- NASA Earth Science Data Preservation Content Specification
- Digital Object Identifiers (DOIs) for EOSDIS
- Data Management Plan Guidance
Note that for newer missions, starting with Soil Moisture Active Passive (SMAP) in 2015, the above requirements have been included in the mission Program Level Requirements. For earlier missions, the above requirements should be applied on a best effort basis. The PCS requirements ensure that all the artifacts needed for users to understand and use the data products are preserved and are accessible in the long-term future. NASA's Distributed Active Archive Centers (DAACs) that are responsible for the data products from the missions store these artifacts along with the products. In some cases, the necessary artifacts may be held by another organization committed to their long-term storage and the DAACs shall have the ability to access the artifacts when requested by users.
For the full list of ESD-approved standards, as well as best practices and lessons learned, please see the Standards and Practices section.
ESO coordinates standards policy and activities within ESDIS. ESO follows a Standards Process for identification of appropriate standards and practices and their subsequent adoption for use in NASA Earth science data systems.

- HDF 4 is being deprecated in favor of HDF 5 and is therefore not recommended for new missions. Although support will still be offered for HDF 4, it will be primarily of a sustainment nature
- HDF EOS 2
- HDF EOS 2 is being deprecated in favor of HDF EOS 5 and is therefore not recommended for new missions. Although support will still be offered for HDF EOS 2, it will be primarily of a sustainment nature
