[OSM-legal-talk] ASTER or no ASTER?
Hi, I'm slowly getting a headache from trying to find out wheter the use of ASTER data (for hillshading) in the creation of CC-BY-SA licensed map tiles is permissible or not. There are people who say that ASTER is only free for science and educational use. I used to think that too. But it's hard to find a good statement about that. From http://www.nasa.gov/topics/earth/features/20090629.html: NASA and Japan's Ministry of Economy, Trade and industry (METI) released the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model (GDEM) to the worldwide public on June 29, 2009. No license info on that page, but release to the worldwide public is something different from for academic purposes only, isn't it? Then http://asterweb.jpl.nasa.gov/gdem.asp: As a contribution from METI and NASA to the Global Earth Observation System of Systems (GEOSS), ASTER GDEM V2 data are available free of charge to users worldwide from the Land Processes Distributed Active Archive Center (LP DAAC) and J-spacesystems. No license info again, but free of charge to users wolrdwide. Hm. Then https://lpdaac.usgs.gov/products/aster_policies gets interesting but the language is somewhat twisted: ASTER Redistribution Policies for the General Public ASTER Global DEM (GDEM) data are subject to redistribution and citation policies. Before ordering ASTER GDEM data, users must agree to redistribute data products only to individuals within their organizations or projects of intended use, ... But this is about the *redistribution* of data, and I don't want to redistribute - I want to make tiles from it. Further down (Click here for additional GDEM redistribution information) it says: 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. ... What are some examples of derived products that are re-distributable? 2. Creating a slope map This all sounds as if I *can* download the data and use it for hillshading as long as I don't redistribute the data itself. Doesn't it?

Re: [OSM-legal-talk] ASTER or no ASTER?
I think it's as clear as a non-standard license can be. As you noted: What are some examples of derived products that are re-distributable? 2. Creating a slope map That's really it in quite explicit terms, I think. My guess is that they want to limit the distribution of the data itself so they would have a bit better understanding of how many organizations/projects/people are using the data. This may impact their financing, etc. .. Just guessing of course.

I contacted NASA and got a response: Our re-distribution policy is the following: You may share GDEM with your colleagues working on the same project. You may re-distribute ANY derived products. A derived product is one where the original DEM values cannot be backed out. So mosaicking several tiles together is not sufficient to re-distribute. But re-sampling the values while creating a different projection can be re-distributed, since the original DEM values cannot be recovered. I'm not sure if that adds much, but it seems that if your hill shading guarantees to obfuscate the original data that seems OK. They don't seem to specify any on-going licence so CC BY-SA should be fine. -- Cheers, Chris user: chillly ___ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
