A rendering of the underlying land topography of Antarctica from data collected for the Bedmap2 project (the vertical scale has been increased by a factor of 17 to improve feature visibility). Some interesting comparison visualisations are available in this NASA article about the Bedmap2 project.
The next iteration of Antarctic map data collection, Bedmap3, is currently underway.
