Also known as formerly: GCMD · formerly: Global Change Master Directory · IDN
The CEOS International Directory Network (IDN) home page and search portal serve as NASA's contribution to the Committee on Earth Observation Satellites (CEOS). IDN's mission is to assist researchers, policy makers, and the public in the discovery of and access to data relevant to global change and Earth science research. The Draft Metadata Management Tool (DMMT) is a metadata authoring tool that IDN contributors can use to propose new or modified CMR records.
