Map projections in the news! And we cartographers are all relieved that it's not the Gall-Peters Projection again. The newer Equal Earth Projection is a much better alternative to Mercator.

[still an excellent teaching aid, and who doesn’t like the idea of mangling a grapefruit with a rolling pin?! (turnips not so much…) ~wink~ ]
“Development in long-range travel and the growing importance of the Arctic and Antarctic regions make it necessary to understand how maps may be misleading. Experiments with a grapefruit illustrate the difficulty of presenting a true picture of the world on a flat surface and it is concluded that the globe is the most accurate way of representing the earth...”

I also love this image from 1921 (!), still useful today, and when I used to teach a little it was part of my coursework… we are so visual…

Cool to see map geekiness pop up on network TV drama a few years back

• I am NOT a fan of the the Galls Peters - thinking that the Equal Earth Projection (https://equal-earth.com/) is vastly superior technically and ‘aesthetically pleasing’
• The 1569 Mercator projection was NOT designed as a ‘tool of cultural oppression’, that is a persistent myth - but rather was "... the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes...”
• As a Trekkie, I also love that the actor John Billingsley - who plays Dr Flox - is the ‘lead scientist’…

[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…”
