Bedrock topography

  • Bed elevation of Greenland:

Bed elevation dataset for Greenland derived from a combination of multiple airborne ice thickness surveys undertaken between the 1970s and 2012, using about 420 000 line kilometres or airborne data and interpolated on a 1km grid.

Ice front position

  • Greenland Ice Mapping Project (GIMP) ice cover mask:

A raster binary land classification mask with 1 for glacier ice and 0 for all other terrain or water from Landsat 7 and RADARSAT-1, mostly 2000.

Ice velocity data for the winter of 2000-2001 and 2005-2006, 2006-2007, and 2007-2008 acquired from RADARSAT-1 InSAR data, and 2008-2009 mosaic derived from the Advanced Land Observation Satelitte (ALOS) and TerraSAR-X data.
