Fantastic! And a color scheme that only a color blind person (like myself) can love! It really shows how little traffic there is on the west coast of the Americas compared to East Asia. Can you share any code for how you did this @tim.hochberg.io?

@paulwoods.io I put together some code at https://github.com/GlobalFishingWatch/spilhaus that should be fairly self contained.

Thanks @tim.hochberg.io ! This will be fun to play with

Also just how much vessel traffic there is off China, much higher that I would have expected.

It turns out that the Spilhaus projection exaggerates the size of the Chinese coastline quite a bit. There is a similar projectioin, called Elastic-2, which is better in this regard. See: https://bsky.app/profile/tim.hochberg.io/post/3leu56qvrrc2y

Cool! But what happened to Australia?

tim.hochberg.io•58 days ago

It got ripped in half and smeared along the edge. You can see that better in this map where they show the land: https://kunimune.blog/wp-content/uploads/2023/12/shaded-relief-elastic-ii.png

You always have to sacrifice something when you make a world map. In this case, it's Australia.

As a South African, I'm totally fine with that ;)
