Map of Greenland: land ice, sea, and bare ground
What it measures. A map of Greenland that labels every spot as land ice, open ocean, or bare ground, giving a clear outline of where the ice sheet sits.
How it's made. Created by combining clear-sky images from the Landsat 7 and 8 satellites with cloud-piercing radar from the RADARSAT-1 satellite.
How & where you'd use it. Serves as a reference layer for studies of the Greenland Ice Sheet, helping researchers separate ice from rock and sea in other analyses.

Official description
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, using a combination of imagery from the USGS Landsat 7 ETM+ and Landsat 8 OLI instruments and Synthetic Aperture Radar (SAR) from the Canadian Space Agency's RADARSAT-1. See <a href="http://nsidc.org/data/measures/gimp">Greenland Ice Mapping Project (GIMP)</a> for related data.
