  1. A Mercator map claimed to divide humanity into two equal geographic groups. My wife asked what it would look like using the Equal Earth projection--so I rebuilt it from an SVG, GeoNames population data, awk, a spreadsheet, and a little CSS. The highlighted countries contain 49.65% of the listed world population.

  5. My latest article for Inquirer.net is now up and I take a look at map projections, and specifically at the Mercator projection popularly used by mapping services such as Google Maps. GIS professionals in particular might remember EPSG:900913 from the late 2000s. 🗺️

  7. Schritt für Schritt zum Orientierungs-Profi - Teil 16: Die Mercator-Projektion

    Bei der Darstellung von dreidimensionalen Körpern wie der Erde auf zweidimensionalen Karten ergeben sich so einige Herausforderungen.

  8. Remember when #DonaldTrump wanted to acquire #Greenland by force if necessary because it was so huge (one of his reasons)? Well, this stems from a common mistake due to using the #Mercator projection. 55 countries in the African Union now voted to replace it with the Equal Earth projection, created in 2018 by Bojan Šavrič, Bernhard Jenny, and Tom Patterson

  14. Happy birthday to Gerardus Mercator (1512-1594) renown Flemish cartographer.

    What made Mercator a great #cartographer, was in fact his abilities as a #mathematician -and like those of us scientists who feel compelled also to create art he was wasn’t hindered by his immense ability as an engraver. He produced beautiful world maps (a version of which is depicted in this print), 🧵1/

  16. I wonder if one reason Trump thinks Greenland is worth fighting for is because it looks really big on a Mercator projection?

  18. Voici un "cercle" de rayon 5000km, centré sur Paris. Projeter une sphère sur un planisphère entraîne des déformations ! (Le choix de la couleur orange n'est sans doute pas complètement anodin.) #mercator ©dranerertiam

  20. Animated comparison of country size on a #Mercator #map

    As we all (should) know, #Greenland is by far the most affected location, due to its distance from the Ecuador

  22. In der Mercator-Projektion wirkt Grönland deutlich größer als in Wirklichkeit. Die flächengleichen roten Kreise der „Tissotschen Indikatrix“ im Bild links machen diese Verzerrung sichtbar. Vielleicht erklärt genau das, warum Trump so große Begehrlichkeiten entwickelt. #Grönland #Mercator

    Warum erhebt Trump keinen Besitzanspruch auf die Antarktis? Die ist noch vieeel gößer als Größtland!

    "and for no reason that the president is able to articulate"

    I still blame - as silly as it sounds - the #Mercator projection on any map

    #Trump sees the island of #Greenland as being far bigger than it is, and in his deluded mind he simply cannot stop obsessing about the hallucination that he can get ***all that*** land just by taking it

    Sooo much land, sooo rich with... stuff

    And China, and Russia might get it first

    Trump is delusional, insane, divorced from any reality that the rest of us share

    Unfortunately, he is not alone in not knowing this. But some do know and still keep using #Mercator. Why? (I do have a guess, #Greenland is not the only country bloated disproportionately in size).
    Boycot Mercator maps. There is no "correct projection," but few are as bad as Mercator (unless you are doing navigational charts, of course).

  30. I'm more and more convinced that #Trump thinks #Greenland is larger than the USA because he's completely incurious and doesn't know about maps.

  32. Wait. So all this is because he didn't realize Greenland wasn't really that big; it's just a Mercator map?!?

  33. @pfsmet There should be a penalty for using #Mercator for any other map than navigational charts.

  35. Lol, the wikipedia page for #Mercator projection has an animated GIF that shows just how much #Greenland is inflated, and the actual sizes
