Mercator Misconceptions - Clever Map Shows the True Size of Countries [Especially In High Latitudes]

[note the ‘true’ size of high latitude landmasses like Greenland and Canada (and Russia as well); note also that the Mercator Projection was not / is not a ‘tool of colonialism’, geopolitics or the like, it was/is ‘simply’ a very clever projection to aid in marine navigation]

Valck Projected onto the Intersection of Six Cylinders

A gentle reminder that a map is not intended to show you the relative size of nation states. That's why we have globes. If you have an inflated sense of Greenland, well, that's pretty much on you.

From Gerard Valck's Nouus planiglobii terrestris per utrumque polum conspectus, 1695.

I wondered what #MapProjection #OpenStreetMap uses and zoomed out as far as possible. It looked like a #MercatorProjection to me.

It kinda was confirmed to me when I scrolled that zoomed out map up and down and the scale shown in the very bottom of the browser window changed from 10000km and being about as wide as the USA or Africa when the map is about centered vertically in the browser window to 1m (with a scale width going 4 times around the globe) at the bottom (shown) and upper ends.

This is pretty crazy; Alaska is only about twice as wide as the Hawaiian islands, though it looks a LOT bigger due to map projection.

[an older paper, but still a wonderful projection IMHO, supported in many GIS softwares and apps now, and rightly so]
“The Equal Earth map projection is a new equal-area pseudocylindrical projection for world maps. It is inspired by the widely used Robinson projection, but unlike the Robinson projection, retains the relative size of areas. The projection equations are simple to implement and fast to evaluate. Continental outlines are shown in a visually pleasing and balanced way…”
