Can I sell maps produced from ASTER Global DEM V2 data?

Question

I don't quite understand the term-of-use of ASTER Global DEM V2 data:

By selecting 'Submit', I agree to the following:

-I agree to redistribute the ASTER GDEM only to individuals within my organization or project of intended use or in response to disasters in support of the GEO Disaster Theme.

-When presenting or publishing ASTER GDEM data, I agree to include 'ASTER GDEM is a product of METI and NASA.'

Does it mean I can't sell maps produced using this data?

Answer 1

Went straight to the source. This was their response:

Greetings,

Thank you for contacting the Land Processes (LP) DAAC User Services.

The general principle is one of reversibility: If someone can recover the original x-y-z values from the new product, then that new product can NOT be re-distributed. This can also be defined as lossless recovery.

Please let us know if you need further assistance.

Answer 2

I've found an explanation by Igor Brejc, author of Maperitive (an OSM-based mapmaking software) at CartoTalk:

By "problematic" I meant the license is much more restrictive than SRTM (which is in Public Domain) and overly complicated, in my view. You cannot redistribute their DEM data or any kind of derivative work that produces a lossless transformation that would allow recovery of the original data (like converting DEM to another format and putting that on some Web server).

You can, however, redistribute hillshadings, 3D renderings and similar derivative work, since it is not possible to reconstruct the original DEM data from such products.

Take a look at https://lpdaac.usgs.gov/customer_service/aster_policies (make sure you click on the "Click here for additional GDEM redistribution information.").

So in a nutshell: we can only distribute (with citations) the derivatives from the original DEM which couldn't be transformed back to recover the original data.
