Alternate Universe Earth

[jwbjerk]

This is a project for a client i had some fun with. It's pretty interesting all the possible coastlines revealed by adjusting the elevation. The job called for a somewhat familiar, but notably different, earth.

I started with a high res elevation map (from Tom Patterson's excellent site), and painted with 1% transparency in white and black, to raise up the sea floor or drown the land. I wasn't too scientific with the plates, though when moving chunks of the world around i often divided things on actual tectonic boundaries. My biggest deviation from reality was breaking the Andes in two. South America's western side looked pretty much the same through huge adjustments of the sea level, and i wanted more variety, so i sunk it to a depth much, much greater than the changes i made elsewhere.

The coloring was a messy combination of gradient maps, masks, and blending mode overlays. I think i ended up with something half-way between a topographic map and a NASA view-from-space, though i had planned to go a bit more toward the satellite look, but it works.

Nice! Except I'm sucking sea water right now!

Me too! Looks awesome though

Thanks!

Your old home may not be available on this world, and there's not quite as much land -- but there is a lot more beach-front property!

True! And I love that you can still make out the shore of what was once Lake Superior.

Fun stuff - like Lex Luthor I seem to have invested in oceanfront property :-).

That muchas hugemondo Gulf of MexicoAndMinnesota is going to be an absolute beast for hurricanes when they hook past the Appalachian Peninsula.

Nicely done. I'm afraid I'm in a watery grave myself at the moment though.
