Digital elevation model, large scale resolution.
Radarsat Antarctic Mapping Project Digital Elevation Model Version 2.

NOTE: This layer's elevation values are based on the OSU91a elevation datum, NOT WGS84. The OSU91a datum provides values closer to "above sea level" but is still based on an ellipsoid and not ground-truthed measurements. Use with caution!
