    Show this map to Trump. He will not want Greenland anymore.

      Acquiring Greenland would move the USA up 2 places in the list of largest countries (past Canada and China). That’s probably why he wants it.

    How much do you wanna bet Trump wouldn’t be so gung ho on Greenland if he saw this map? He probably thinks he is going to double the size of America.

      Trump handlers want the resources. Trump wants it because his ego is inflated by mercator projection.

      Eh, I doubt that’s the case. It could be a 20 m^2 area, but if it had Greenland’s resources they would want it.

    I don’t think that’s the true size. You’ll find all those countries are actually a lot bigger than presented on that map and scaled down to fit on a screen

    Yes, but blue (Mercator) preserves direction and shape, which were all that really mattered for navigation by sea, so Mercator was a fantastic projection for centuries.

    And we still use it today for smaller scale areas, since it does a remarkably good job at preserving all 4 features (shape, area, distance, and direction) close to the map origin line. Universal Transverse Mercator is a system that has 60 zones of Mercator turned sideways.

    The reason it’s Transverse is because, unlike lattitude depending on a defined equator, longitude has an arbitrary meridian, so by turning the map sideways we can move the distortion point, and any map area that doesn’t stray too far East or West will be very accurate.

    Think of trying to map something like Chile or Florida, where the area of interest is pretty far North to South, but not East to West.

    Why is the difference only extremely pronounced in the northern hemisphere? If I understand the math behind the projection correctly, the equator should be true scale, and things should vary more the further north AND south you go.

    This image shows the extreme southern latitudes to be almost equal to their true area. Is the image wrong, or am I misunderstanding something about the projection?

      This map is clipping a good chunk of the Southern Hemisphere. When you include it, you also notice the same distortion:

      Note how it looks like Antarctica (14*10⁶km²) is 1/4~1/5 of the globe, even if it’s actually smaller than South America (18*10⁶km²).
