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:

The Spilhaus Projection for Designers
The Spilhaus projection has been available to ArcGIS Pro users for nearly two years. Now, to expand the Spilhaus’s availability beyond ArcGIS users, John Nelson provides vector assets suitable for designers working in, say, Illustrator.

The Spilhaus Projection Comes to ArcGIS Pro
As John Nelson promised last September, with the release of ArcGIS Pro 2.5, the popular and viral Spilhaus projection is now available in ArcGIS Pro.
Everything’s Coming Up Spilhaus
John Nelson reports that the Spilhaus projection will be supported in the next version of ArcGIS—version 2.5, to be released in a few months. This odd projection, which centres Antarctica on a world map showing the oceans as a single, uninterrupted body of water; went viral last year. Requests for ArcGIS support soon followed. Thing is, ArcGIS support requires the math behind the projection: figuring out that math took some sleuthing. The Spilhaus is, it turns out, basically an oblique aspect of the Adams World in a Square II projection.

About the Spilhaus Projection
This image went a bit viral earlier this week. Some context. It’s from an August 2015 blog post at Le Cartographe, in which Alexandre Nicolas discussed (and rendered, above) a projection produced in 1942 by South African oceanographer Athelstan Spilhaus. In Spilhaus’s oceanic projection, centred on Antarctica, the world’s oceans form a single, uninterrupted body of water. Which, you know, it is. The continents form the edges of the map; there is … some … spatial distortion. As Alexandre wrote in 2015, “This projection is rarely used and it’s a real shame!”
