An Inverted Earth You Can Explore

In honor of the #30DayMapChallenge's Inverted theme, Tripgeo has released Atlantis - the Inverted Earth.

I've seen a few maps that swap the Earth's land and oceans around, turning familiar continents into vast underwater worlds and ocean basins into towering mountain ranges. But this is the first I've encountered that lets you actually explore the resulting world from the cockpit of your own submarine.

In Atlantis: The World Turned Over, the oceans have drained onto the continents, leaving the former seabed exposed as enormous mountain ranges. Meanwhile, every city on Earth has been submerged beneath the newly formed oceans.

Your vehicle for exploring this topsy-turvy planet is the Nereid, a fully navigable submarine that you can pilot directly in your browser. You can dive through the drowned streets of familiar cities, explore submerged urban landscapes and venture into the newly flooded continental interiors. You can even use sonar to sound the depths of the inverted world's ocean trenches.

One of the most intriguing aspects is seeing familiar places transformed by this geographical reversal. Imagine navigating the streets of Paris, except instead of walking along the Seine, you're piloting a submarine through an underwater city.

The newly emerged ocean floors also provide a spectacular new geography to explore, with the world's deepest trenches now standing as immense mountain ranges.
