The National Maritime Museum in Greenwich, London has a new attraction. “The Ocean Map is a giant, 440m² floor map that turns our view of the world inside out. While most world maps focus on countries and continents, the Ocean Map is all about water.” You can probably see where this is going: the Museum’s floor map uses the Spilhaus projection. Here’s a preview from before the hall in which it’s situated reopened on June 7:

I'm genuinely SO excited about the new ocean map that will be at the heart of the National Maritime Museum in Greenwich when this hall reopens on June 7th. It's an unusual ocean-focussed map with so much detail, and it's just brilliant. 🌊🌊 Here's a sneak peak.www.rmg.co.uk/stories/ocea…
