Fred is right. It's the Potsdam Gravity Potato
basically an earth homunculus
Look at the scale on the right... The height difference is +/- 80 meters. You would never see that difference at this scale, therefore the graphic is exaggerated to allow us to see this difference. So this is not the Earth without water - it is a graphical representation of the height of the Earth’s crust in meters.
This is the gravity mapping done a few years ago - differences in the measure of gravity around the earth.
