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. Ice cover was mapped using a combination of orthorectified panchromatic (band 8) imagery from the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), distributed by the USGS, and … arctic gimp greenland ice nasa polar -
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 -
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 gimp greenland nasa polar -
MEaSUREs Greenland Ice Velocity: Selected Glacier Site Velocity Maps from Optical Images Version 2
This dataset, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, consists of mean monthly velocity maps for selected glacier outlet areas. The maps are generated by tracking visible features between optical image pairs acquired by the Landsat … arctic gimp greenland ice nasa polar -
