This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides a complete land ice and ocean classification mask for the Greenland ice sheet, that was mapped using a combination of USGS Landsat 7 ETM+ panchromatic band imagery, and the Canadian Space Agency's (CSA) RADARSAT-1 Synthetic Aperture Radar (SAR) amplitude images.

The previous version incorrectly specified the location of the upper left pixel as the distance in meters from the north pole to the center of the upper left pixel. The corrected location of the upper left pixel is the distance in meters from the north pole to the upper left corner of the upper left pixel. This correction effectively shifted the location by one-half pixel to the upper left relative to their positions in the previous version. Only the geolocation metadata in each GeoTIFF have changed; the data array is the same as in the previous version.1999-07-012001-09-3001.2This version includes the following updates:
-Ice and ocean masks for the year 2015 were added. A grounded ice mask for 2015 was not included with the update.
-The year, “2000” was added to existing file names to differentiate them from the 2015 files.2013-01-152015-09-300NSIDCCurrent Version1NSIDCSpatial Reference SystemsEPSG:3413WGS 84 / NSIDC Sea Ice Polar Stereographic NorthNSIDCLevel of ServiceStandardNSIDCFull Dataset CitationHowat, I. 2017. <i>MEaSUREs Greenland Ice Mapping Project (GIMP) Land Ice and Ocean Classification Mask.</i> [indicate subset used].
