There was a memorable scene from "The West Wing" on the biases imposed by most map projections, in particular, how Mercator makes North America look huge: https://www.youtube.com/watch?v=eLqC3FNNOaI

It's fascinating how we're expected to believe senior White House officials are such perfect strawman doofuses that they have never seen a globe or the Mollweide projection, or were ever reprimanded by a geography teacher for saying "up" instead of "North". The only thing that scene is missing is for her to fall over in shock and disbelief at hearing that the Earth is round.

They're not characters, they're tools to push a message.

Right? Is there a person above 25 that hasn’t seen the episode (or clip) from The West Wing about map projections at this point?

Pretty cool to think about the amount of work going on behind the covers to alter these projections on the fly. And how costly it was to build them originally by hand.

work, sure, but not _that_ much. It's affine transformations / some fast linear algebra, for the most part. Your second point is for sure true, though.

I wonder if anyone ever came up with an elaborate mechanism connected to a pen.

It is fiction. Relax and enjoy the show.

> Every flat map projection distorts something, so every projection has to optimize some parameter and trade off other utility. I'm constantly amazed at how hung up people are on apparent size of countries. If size is your thing, use some other projection! That's the point of the post.

> That's the point of the post. I lost it in the post. Whenever I hear the “crisis” part presented without the perfectly rational explanation I get frustrated and spend more time trying to figure out if this is a problem. Saying “maps distort the way we see the world” is a problem unless you immediately follow it with “and that’s ok because…” Otherwise we waste time on stuff like “eyeballs distort the way we see the…

The poor countries claim has a footnote and a promise to explore it in another article. It doesn't say anything further about this.

The article also doesn't answer whether the distortions are intentional, a side-effect, a trade-off, or a combination of some of this. The author promises a follow-up article, unfortunately a "premium" one which I suppose you must pay for (edit: sadly, it's paywalled: https://unchartedterritories.tomaspueyo.com/p/are-maps-decei...)

Every flat map projection distorts something, so every projection has to optimize some parameter and trade off other utility. I'm constantly amazed at how hung up people are on apparent size of countries. If size is your thing, use some other projection! Mercator is and remains popular because it preserves local angles and shapes, which makes it simple use this projection to navigate by rhumb lines (compass headings)…

> I'm constantly amazed at how hung up people are on apparent size of countries. If size is your thing, use some other projection! Hmm. That’s not usually how the discourse goes. It’s never “wow, Country X is actually smaller than Country Y. That’s terrible.” It usually goes something like “wow, Country X is actually smaller than Country Y. This distorts our worldview and makes us think things we shouldn’t have thoug…

> But my thoughts about Europe definitely changed after seeing the other projection.

Can you elaborate on that ?

Did you think bigger = better ?

Andrew Jackson, in the main foyer of the White House, had a two-ton block of cheese. It was there, for any and all who were hungry, it was there for the voiceless.

So... government cheese?

> But my thoughts about Europe definitely changed after seeing the other projection. That’s odd. Did you think land mass was somehow really important? Did you ever check out how small Britain or Spain or Portugal or Netherlands were to the size of their empire. Do you now think that Indonesia is more important because of its size? I would expect that revelations about population would be more worldview adjusting (Nig…

You have a fixed and narrow definition of what important means.

Importance should change depending on context.

Sure, you are definitely allowed to say that a certain metric (i.e. population size or density) has more practical applications and provides better signal for “blah blah”.

But I’m not discussing “blah blah”.

The only way I could enjoy that farce is after multiple, life-alteringly serious concussions.

The overlay of Canada on Europe is always a fun one. We moan so much here (perhaps rightfully so) about lack of public transit and reasonable infrastructure to get around, but we're also comparing a population of (just recently hit!) 40,000 and ~700,000. Orders of magnitude larger, but roughly same land area. This is why I am hugely in support of increased immigration into Canada, housing crisis aside (it'll resolve…
