Digital artist Kevin Gill has just given that thought experiment one hell of a visualization: his ‘A Living Mars’ rendering has made the blog-rounds, and for good reason. It’s a painstaking nonscientific realization of a “wet” Mars, with Earth-like continents and bodies of water.
I’ll just let him do the explaining:
This is a view of the Western hemisphere with Olympus Mons on the horizon beyond the Tharsis Montes volcanoes and the Valles Marineris canyons near the center … The completed model was done in several steps…
A two dimensional digital elevation model was first rendered in jDem846 (an open-source learning project of mine) … In that model, I picked a sea level and scripted it such that terrain at or below that level was flat and blue.
