The world maps we know all misrepresent the world itself: we've all heard it many times before, but how well do we understand the nature of that misrepresentation? "For many people, the Earth as they know it is heavily informed by the Mercator projection – a tool used for nautical navigation that eventually became the world’s most widely recognized map," writes Visual Capitalist's Nick Routley. But the Mercator projection dates to 1569, and "the vast majority of us aren’t using paper maps to chart our course across the ocean anymore, so critics of the Mercator projection argue that the continued use of this style of map gives users a warped sense of the true size of countries."
Some of the geographical misconceptions Gerardus Mercator inadvertently instilled in humanity to this day include exaggerations of the size of Europe and North America. "Visually speaking, Canada and Russia appear to take up approximately 25% of the Earth’s surface" on a Mercator map, "when in reality they occupy a mere 5%."
Figures are one thing, but a fair few 21st century cartography enthusiasts have also used technology unavailable and indeed unimaginable in Mercator's day to show us in a more immediately legible way exactly how his projection distorts land masses. Recently, a climate data scientist named Neil Kaye has used the form of the animated GIF to show what happens when countries shrink to their actual size on a Mercator map, and when Mexico and Greenland trade places.
As soon as Mexico goes north and Greenland goes south, it becomes obvious that both are really of a similar size, though we might have assumed the latter to be much larger than the former. And in fact, Mercator projection makes all countries farther from the equator look larger in relation to all countries nearer to the equator. We've pointed out the impossibility of making a perfectly faithful two-dimensional world map before here before on Open Culture, an impossibility that hasn't stopped cartographers from trying to come up with more and more accurate projections. But even they can't substitute for an acute awareness of how even the most popular maps can be wrong, an awareness you can develop even more intensively by viewing the many other cartographic creations Kaye has posted to the "Map Porn" subreddit — another technological development Mercator surely couldn't have foreseen.
