Neue Projektion der Welt: AuthaGraph Worldmap


Hajime Narukawa hat diese Woche den Good Design Award mit seiner neuen Projektion der Kontinente und seiner AutoGraph-Weltkarte gewonnen. Ist eine Weiterentwicklung von Buckminster Fullers Dymaxion map, ergibt aber eine genauere Abbildung der Landmassen, die darüber hinaus wie eine MC-Escher-Grafik mosaiktisch aufgebaut ist, das heisst, man kann die Karte endlos in ihrem Rahmen verschieben und erhält immer eine stimmige Karte.

authagraph-world-map-3The 2016 winner of Japan’s prestigious Good Design, designers figured out how to translate our spherical world into a rectangular box. Hajime Narukawa, a Tokyo-based architect and artist, broke the globe up into 96 regions and folded it into a tetrahedron and then a pyramid before finally flattening it into a two-dimensional sheet. The multi-step process preserves the true dimensions of the continents by angling them outward instead of stretching them, maintaining the illusion that they’re all laid out vertically like we’re used to. Their website states that the goal was to create map better suited to address the problems of the 21st century, including rapidly diminishing sea ice and territorial claims of marine territory, by more accurately depicting what areas near pole actually look like.

Called the AuthaGraph, the result is a map that looks a little different that most of us are used to. Seen in rectangular form, Antarctica is intact and at the bottom right.


AuthaGraphic Projection
An original method for maintaining areas proportions is called "iso-area-mapping." And an original mapping process by combining different projection methods via intermediate objects is called "multilayer-mapping." These ideas for mapping aims to reduce errors during projecting a sphere to a tetrahedron because a simple optical projection from a sphere to a tetrahedron causes huge distortions therefore useless.


Comparison/ Rectangle or Accuracy
AuthaGraph map is able to transform an entire sphere to a rectangle as Mercator projection does while it substantially keeps sizes and shapes of continents as Dymaxion map does.


the World without Ends
It is able to tile the AuthaGraphic world map without gaps and overlaps. The way of tessellation has seamless connections between maps as if it is an Escher’s tiling. Same as fishes and birds in his painting, six continents are never fragmented and seven oceans keep their continuous networks. It had been thought the world is on an infinite plane since geometries of a sphere and of an infinite plane are similar. Walking on both surfaces, we do not meet an end. A geographical network in the map is able to expand to any directions on the tessellated maps. Thus the world map reproduces the spherical world without dead end on a plane.

World Map Re-arrangements
On the tessellated maps it is able to frame a view field covering a full set of a world. The frame functions as a viewer which enables user to slide and rotate and then to frame a new world map with a preferable region at its center. They provide a new angle of perspective to equally view the world so as to be free from existing perceptions defined by usual phrases such as “far east”, “go up north”, “Western”.


ISS Long-term Tracking
An orange line on tessellation-world composed by 49 maps tracks a journey of International Space Station (ISS) for eight hours. Its coordinates are provided by ‘Cerestrak’, a website distributing ISS’s orbital data. NASA and the US department of defense issue the original data. The coordinates are defined by calculating the data to reflect corrections of the orbit.
