This image went a bit viral earlier this week. Some context. It’s from an August 2015 blog post at Le Cartographe<\/a>, in which Alexandre Nicolas discussed (and rendered, above) a projection produced in 1942 by South African oceanographer Athelstan Spilhaus<\/a>. 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<\/em> … spatial distortion. As Alexandre wrote in 2015, “This projection is rarely used and it’s a real shame!”<\/p>\n
