The revolutionary map and globe that won the 2016 Japan GOOD DESIGN GRAND AWARD

The more north or south you go, the more distorted the area and shape of the "Mercatorian" world map we are used to seeing. The AuthaGraph is a groundbreaking map designed to ensure that the true relative size and shape of continents and oceans are not distorted. This map will change your view of the world.

The AuthaGraph World Map Poster (a world map in one)

The AuthaGraph World Map is the latest innovative world map that represents the components (continents, oceans, etc.) of a spherical map in the most accurate relative size possible on a two-dimensional map. This AuthaGraph world map poster is arranged around the Pacific Ocean, and you can see Antarctica close to the South American continent in the lower right of the map.

A world map poster that can be framed or pasted directly on the wall

We deliver a world map using the AuthaGraph projection method in a handy poster format. It can be pasted directly on the wall or framed, but framing makes it look more luxurious.

This world map is produced by the following procedure.

1. The surface of the globe is divided into 96 rectangular tiles.
2. These 96 tiles are projected onto an inflated tetrahedron with 24 tiles on each side while maintaining the area ratio of each tile.
3. The expanded tetrahedron is flattened into a regular tetrahedron, while maintaining the area ratio of each tile.
4. The expansion of the tetrahedral globe cut open will be a rectangular world map with an aspect ratio of √3:4.

The AuthaGraph Globe

This AuthaGraph Globe is a paper craft globe kit showing the process making a 2D AuthaGraph world map. The package contains three different sets of paper parts for the globe of the sphere, the globe of the intermediate body, and the globe of the regular tetrahedron (AuthaGraph). By assembling these globes, you can understand how spherical earth changes to a 2D AuthaGraph world map in a three-dimensional transformation process.
