ASTER GDEM Version 3 (ASTGTM V003) was released on August, 5, 2019 and contains no redistribution requirements. The LP DAAC kindly requests that you properly cite the data in your research. Pre-populated citations for the product can be found on the DOI Landing Page for the product under the "Citation" section. Users are encouraged to use ASTER GDEM Version 3 going forward as ASTER GDEM Version 2 data are no longer available from the LP DAAC.
Previously ASTER GDEM Version 2 (ASTGTM V002) data required users to agree to only redistribute data products to individuals within their organization or project of intended use, or in response to disasters in support ofthe GEO Disaster Theme prior to downloading data. In addition, the following sentence was required to be included in publications that used the data: "ASTER GDEM is a product of Japan’s Ministry of Economy, Trade, and Industry (METI) and NASA." Projects that are continuing to use ASTER GDEM Version 2 data are required to continue following these redistribution and citation requirements. "
