AuthaGraph World Map [PLATINUM]

The Winner of 2016 GOOD DESIGN GRAND AWARD in Japan!

AuthaGraph World Map “our planet on tetra and rectangle.”

Route plans or trip schedules may be drawn and erased on the map using whiteboard pens.

The AuthaGraph world map is a modern innovative map that frames the world’s physical components (continents, seas, etc.) in a 2D rectangle while representing their relative sizes and the shape of coastlines as accurately as possible. Antarctica, for instance, can be seen at the bottom right, close to South America. This map is designed to place the Pacific Ocean in the center position.

This 'AuthaGraph' World Map is generated through the following process:
1. Globe surface is divided into 96 oblong tiles.
2. These 96 tiles are projected on an inflated tetrahedron having 24 tiles on each face while maintaining the area ratio of each tile.
3. The inflated tetrahedron is flattened into a regular tetrahedron while keeping the area ratio of each tile.
4. A development diagram obtained by cutting out the regular tetrahedron globe becomes a rectangular world map in a √3:4 aspect ratio.
