Two maps of the same world, locked together: pan or zoom the 1569 Mercator on the left and the Equal Earth projection on the right follows, so the only thing that changes between them is the maths. Hover a country and it lights up on both; drag one from either map and drop it on another to see the overlap. Greenland, Mercator’s most famous lie, shrinks to a fourteenth of Africa in front of you. The site credits Equal Earth as the UN’s map projection as of this year.
