AuthaGraph World Map Wins Japanese Design Award


Japan’s Good Design Awards have been announced for 2016, and the Grand Award has gone to an unusual map. The AuthaGraph World Map “is made by equally dividing a spherical surface into 96 triangles, transferring it to a tetrahedron while maintaining areas proportions and unfolding it to be a rectangle.” Follow that? Sphere to tetrahedron to rectangle.

The brainchild of designer Hajime Narukawa, the AuthaGraph map was first released in 2010. What’s it for? In many ways it’s sort of a Japanese Peters projection: it aims to maintain the relative sizes of the continents. From the page selling the map outside Japan:

Every world map that has been invented since the Mercator Projection was first revealed in 1569 can be divided into two groups. One group fits the world into a rectangle by distorting the continents. The other group corrects the distortion, but at the cost of the rectangular shape. This is what drove Narukawa to create a map which is rectangular like the Mercator Projection map, and yet correctly projects the continents like the Dyxmaxion Map (revealed in 1946).
