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, or in response to disasters in support of the GEO Disaster Theme. When presenting or publishing ASTER GDEM data, users are required to include a citation stating, "ASTER GDEM is a product of METI and NASA."
USGS's as all federal agency's works are by the American law within the Public domain. Then, they push push to keep the distribusion centralized : they don't want forks appearing around the web. Same for the citation: that make sense academically. This is their wishes, but not law. I'm pretty sure the file are PD. Yug(talk) 22:54, 18 May 2012 (UTC)[reply]
They say that you cannot distribute the data or distribute anything that allows the data to be recreated from your work:
"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."
"Can images created for publication or Web 2.0 applications (e.g., Wikipedia) using ASTER GDEM data be re-distributed?
Images that are created using GDEM data may be re-distributed through publications or social media applications. Papers citing such articles may be re-distributed as well."
They make it sound like it is more about capturing usage data - the registration form was quite detailed (it wanted institution, phone number etc) and I needed to select between one of the following to download the data: "disasters, health, energy, climate, water, weather, ecosystems, agriculture, or biodiversity". However it was produced by NASA.. Secretlondon (talk) 00:32, 19 May 2012 (UTC)[reply]
Data is not recoverable from our maps. Clearly. With all the cuts, colorations, vectorisations, icons we add, while you have the original source just out there. Our job is not data redistributions, it's illustration. Yug(talk) 17:52, 19 May 2012 (UTC)[reply]
Hi, guys. Has anyone here managed to use the new SRTM V3.0 (aka SRTM Plus/Void Filled) in Wikipedia maps? It says here that, "The NASA Version 3.0 SRTM Global 1 arc second product is void-filled using elevation data from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) Global Digital Elevation Model 2 (GDEM2), USGS Global Multi-resolution Terrain Elevation Data (GMTED) 2010, and USGS National Elevation Dataset (NED)." I found this link after digging through USGS and NASA's websites. Here is the profile for SRTMGL1, the one mentioned in the article. Has anyone here tried it? Sorry for bad English.
