Greenland-wide satellite image map, year 2000

MEaSUREs Greenland Ice Mapping Project (GIMP) 2000 Image Mosaic V001
cryosphere NASA NSIDC_CPRD Level 3 GeoTIFFASCII
In plain English

What it measures. A seamless picture-map of the entire Greenland ice sheet around the year 2000, sharp enough at 15 m to pick out topography, large crevasses, and other surface features, with extra layers describing surface properties like snow grain size and bare rock.

How it's made. Stitched together from Landsat 7 optical imagery and RADARSAT-1 radar imagery collected between 1999 and 2002 into a single mosaic.

How & where you'd use it. Gives glaciologists a baseline view of Greenland's ice surface to compare against later years and to study features like crevasses, bedrock outcrops, and melt areas.

Official description

This data set, part of the NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides a complete 15 m resolution image mosaic of the Greenland ice sheet, derived from USGS Landsat 7 ETM+ imagery and Canadian Space Agency's (CSA) RADARSAT-1 imagery from the years 1999 to 2002. Additional bands (some at 30 m resolution) are provided for each tile in the mosaic and are useful for understanding surface properties, such as snow grain size, bedrock outcrops, mapping layering in the snow, and blue ice or lake-filled regions, during the spring and summer months. The panchromatic (band 8) mosaic provides the highest-resolution view of the ice sheet surface at 15 m, resolving topographic features, large crevasses, and other geophysical structures.
