Are there any restrictions on using this model?

Just two: ETOPO1 cannot be used for navigation, and products derived primarily from NCEI data are not subject to copyright protection in the United States (see copyright). We do ask that you acknowledge NCEI as source.. Do I need permission to use ETOPO1 or its color images?

It is not necessary to obtain written permission to use ETOPO1 or other NOAA products that are in the public domain, nor are there any fees for using them. We ask only that you cite NCEI as source.
