Thank you for your interest in NASA’s Earth Observing System Data and Information System (EOSDIS).

The NASA Earth Observatory has a link on their website to their terms for image usage: http://earthobservatory.nasa.gov/ImageUse/

A quick summary includes:

Most materials published on the Earth Observatory, including images, are freely available for re-publication or re-use, including commercial purposes, with the following exceptions:

• where copyright is indicated, you must obtain the copyright holder’s permission; we usually provide links to the organization that holds the copyright,
• images from the SeaWiFS sensor older than five years are in the public domain and can be re-used or re-published for any purpose
• images less than five years old can be re-used only for educational or scientific purposes
• any commercial use of such images must be coordinated with GeoEye.

We ask that NASA’s Earth Observatory be given credit for its original materials; the only mandatory credit is NASA.
