    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.

    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.

      The Goode Homolosine projection. You lose accurate direction, shape, AND size to a degree, but less size issues than some projections. It’s a good way to remind kids that the world is round, but once you try to use it for anything like showing a route or visualizing relative distances, the limitations become significant.

    This is why Trump wants Greenland so bad. He sees it, and says “It’s big, I want it. Get it for me!” and gets all Veruca Salt about it.

    All because he doesn’t understand what a Mercator Projection is, on account of he beat up some nerd to do his homework that day, like every day.

      A lot of conservatives have wanted Greenland for a long time as some throwback to US imperialism and very outdated cold-war era defensive posturing.

      Stephen Miller threw the idea at Trump and wormtongued it as some idea that claiming the country would be some monument to Trump’s legacy that would outlive all the scandals, and that’s all the old turd wants, he just wants adoration and cheering crowds, that’s his entire ethical framework.

      What does Miller want from it? No idea, he’s utterly, inhumanly insane. He’s just literally an Elliot Rodgers in a suit who managed to get way too much power.

        The Dems need to make a major case out of PeeWee Himmler for the Midterms. Expose him, and add him to the list of horrors that we are running against.

          I feel strongly part of why he’s even more “shrieky” and unhinged than normal is because the GOP broadly has NO plan right now for when Trump keels over. They tried so desperately hard to parade JD Vance around to get him ready to take the reigns, but so far MAGA haaates him, he talks like a politician, he has all that inhuman proceduralism that made people embrace Trump’s open hatred and malice.

          So Miller is slowly realizing once Trump dies, which could be any moment, that he’s going to potentially face charges, and all the comparisons to people who met their end on a rope are likely dancing around in the back of that huge, empty skull.

        I don’t want people associating Stephen Miller with a Brad Dourif character.

        Mr. Dourif is a saint, and mensch, and doesn’t deserve that smoke.

          The good news is Dourif is such a good actor and played such an iconic character in that role, that I doubt anyone is going to connect him to the apt-term that is already spreading through public lexicon.

    Anyone know of a 2D map print of true size? All I’ve found print wise is Mercator or other such variations.

      Technically, the outer surface of a sphere is, itself, two-dimensional. It is, however, non-Euclidean and cannot be perfectly preserved in a Euclidean two-dimensional space.

        Equal area projections usually preserve straight and perpendicular meridians and parallels. That’s neutral but then there’s the political decision of what latitude gets the correct aspect ratio. And Gall-Peters is not anti-colonialist if representing Africa correctly was your goal.

          Essentially this. A true sized projection, it can be in any “cut” of the globe as long as all the continents are true to size.

        They want a 2d map of earth but with every continent to true size at scale, rather than Mercator projection where the northern hemisphere is expanded to increase their importance over the southern hemisphere.

          Mercator wasn’t created in order to increase importance of the northern hemisphere, but to allow for directional rhumb lines to be drawn for shipping. For its intended purpose of navigation, it does an excellent job.

            It may not be the intended purpose but I certainly does change how the world is seen by everyone using it to warp the mind’s eye to how the world actually physically is.

            Edit: Does it do an excellent job for navigational purposes if you are shipping from Japan to Brazil or it it only excellent for shipping from the northern hemisphere to the northern hemisphere?

      I don’t know what you mean by “other such variations”, but maybe you are looking for a map with something like the Mollweide projection? That’s a bit of distortion in shape but trying to keep areas real.

          The projection is the mathematical transformation from the curved surface of the Earth to a mathematical surface. You can have types of projections based on the mathematical surface (conical, cylindrical…), or based on the features they want to rescue from this transformation (conformal, equal-area…), but, sorry, I’ve never heard of a classification based on these “slices”. Moreover, now that I think of it, even those projections we are familiar with have to be cut somewhere.

              No, I know what you mean but that looks like some azimuthal projections put together in some conventional way. Maybe the concept you are looking for is a “composite” projection?

        No, because Africa is larger than Russia, this shows Russia as massive.
