Griggs, J. A. and J. L. Bamber. 2009. A New 1 km Digital Elevation Model of Antarctica Derived from Combined Radar and Laser Data – Part 2: Validation and Error Estimates. The Cryosphere, 3, 113–123.This data set provides a 1 km resolution Digital Elevation Model (DEM) of Antarctica. The DEM combines measurements from the European Remote Sensing Satellite-1 (ERS-1) Satellite Radar Altimeter (SRA) and the Ice, Cloud, and land Elevation Satellite (ICESat) Geosciences Laser Altimeter System (GLAS). The ERS-1 data are from two long repeat cycles of 168 days initiated in March 1994, and the GLAS data are from 20 February 2003 through 21 March 2008. The data set is approximately 240 MB comprised of two gridded binary files and two Environment for Visualizing Images (ENVI) header files.VIEW RELATED INFORMATIONhttps://nsidc.org/sites/default/files/nsidc-0422-v001-userguide.pdfAntarctic 1 km Digital Elevation Model (DEM) from Combined ERS-1 Radar and ICESat Laser Satellite Altimetry, Version 1 User GuideGET DATAhttps://daacdata.apps.nsidc.org/pub/DATASETS/DEM/nsidc0422_antarctic_1km_demHTTPSCEOS IDN DIFVERSION 9.92009-12-082026-06-24NSIDCVersion SummaryInitial releaseNSIDCMinor VersionNSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:4326WGS 84NSIDCLevel of ServiceStandardNSIDCFull Dataset CitationBamber, J.
