Bathymetry and MEaSUREs Ice Velocity
Hillshade and Bathymetry
Layer group comprising DEM hillshade dataset with a suitably styled surface DEM.
MEaSUREs InSAR-Based Antarctica Ice Velocity
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) Program, provides the first comprehensive, high-resolution, digital mosaics of ice motion in Antarctica assembled from multiple satellite interferometric synthetic-aperture radar systems. The majority of the data were acquired during the International Polar Year 2007 to 2009.
