Greenland Ice Sheet Mapping Project (GrIMP)
- Image Mosaic (15 m resolution, pan-sharpened)
Mosaiced Landsat ETM+ and RADARSAT imagery from the years 1999 to 2002 - Ice and Ocean Masks (15 m resolution)
Raster binary land classification mask for the ice sheet and peripheral glaciers and icecaps and coastline - Digital Elevation Model (30 m resolution)
A combination of ASTER and SPOT-5 DEM's for the ice sheet periphery and margin south of approximately 82.5°N, and AVHRR photoclinometry in the ice sheet interior and far north. - Outlet Glacier Velocity Maps
Mean monthly velocity maps for selected glacier outlet areas. The maps were generated by tracking visible features between optical image pairs acquired by the Landsat 7 Enhanced Thematic Mapper Plus (ETM+), the Landsat 8 Operational Land Imager (OLI), and the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER).
