2000 Greenland Mosaic - Greenland Ice Mapping Project (GIMP)
This dataset provides a complete 15 m resolution image mosaic of the Greenland ice sheet derived from Landsat 7 ETM+ and RADARSAT-1 SAR imagery from the years 1999 to 2002. The methods include a combination of image cloud masking, pan sharpening, image sampling and resizing, … arctic gimp greenland imagery nasa polar -
CryoSat-2 Antarctica 1km DEM
This dataset is a digital elevation model (DEM) of the Antarctic ice sheet and ice shelves based on observations recorded by the CryoSat-2 satellite radar altimeter between July 2010 and July 2016. The DEM is formed from spatio-temporal fits to elevation measurements accumulated within 1, … antarctica dem elevation elevation-topography polar -
Greenland DEM - Greenland Mapping Project (GIMP)
This Digital Elevation Model (DEM) is constructed from a combination of ASTER and SPOT-5 DEM's for the ice sheet periphery and margin (i.e. below the equilbrium line elevation) south of approximately 82.5°N and AVHRR photoclinometry in the ice sheet interior and far north (Scambos and … arctic elevation-topography gimp greenland nasa polar -
Greenland Ice & Ocean Mask - Greenland Mapping Project (GIMP)
This dataset provides complete land ice and ocean classification masks at 15 m for the Greenland ice sheet.
