Global Digital Elevation Model
 (JPG) (1,153,192 bytes) ( 4,320 x 2,160 )
NASA and Japan‘«÷s Ministry of Economy, Trade and Industry (METI) announced the release of the ASTER Global Digital Elevation Model (GDEM) on June 29, 2009. The GDEM was created by stereo-correlating the 1.3 million scene ASTER VNIR archive, covering the Earth‘«÷s land surface between 83N and 83S latitudes. The GDEM is produced with 30 meter postings, and is formatted in 23,000 1 x 1 degree tiles as GeoTIFF files. Each GDEM file is accompanied by a Quality Assessment file, either giving the number of ASTER scenes used to calculate a pixel‘«÷s value, or indicating the source of external DEM data used to fill the ASTER voids. The GDEM is available for download from NASA‘«÷s EOS data archive (https://wist.echo.nasa.gov/~wist/api/imswelcome/) and Japan‘«÷s Ground Data System (http://www.gdem.aster.ersdac.or.jp/index.jsp). This ASTER product is available at no charge for any user pursuant to an agreement between METI and NASA.
