What is the CEOS IDN?


The Committee on Earth Observation Satellites (CEOS) IDN site is an international effort developed to assist researchers in locating information on available data sets. The CEOS IDN Directory provides free, online access to information on worldwide scientific data in the Earth sciences: geoscience, hydrospheric, biospheric, satellite remote sensing, and atmospheric sciences. The CEOS IDN Directory describes data held by university departments, government agencies, and other organizations.


Frequently Asked Questions:

1) What is the difference between the Global Change Master Directory (GCMD) and the International Directory Network (IDN Directory)?


The Global Change Master Directory (GCMD) is a directory of Earth science data and services, funded by NASA for the purpose of tracking and subsequently locating NASA's Earth science data. The International Directory Network (IDN) Directory is part of NASA's contribution to CEOS for international Earth sciences efforts. It extends the GCMD capabilities for use by interagency and international collaborators.

2) What is an IDN website?


The International Directory Network (IDN) offers the full directory, to participants and groups to emphasize their contribution, track their data holdings, and their content as part of the larger collaborative effort.

3) What is the method of communication among the worldwide participants?


The Interoperability Forum provides a vehicle for communication related to the Directory Interchange Format (DIF). It is through this Forum that additions, deletions, and modifications to these standards are made, in conjunction with ISO and other standards organizations.
