The ‘AuthaGraph’ World Map Poster

The Mercator Projection, named after geographer Gerardus Mercator (1512 ~ 1594), is the map of the world first revealed in 1569 that is still the generally accepted image we have of the planet. It is flawed, however, in that it dramatically distorts the sizes of Antarctica and Greenland (Antarctica was yet to be discovered when the Mercator Projection was invented). The AuthaGraph by contrast, is a modern innovative map that frames the world’s physical components (continents, seas, etc.) in a 2D rectangle, while representing their relative sizes as accurately as possible. Antarctica, for instance, can be seen at the bottom right, close to South America, Africa and Australia.

Flat Earth without ends!

The ‘AuthaGraph’ World Maps Poster

It matters not in which direction we choose to walk, the end of the Earth clearly can never be reached. In a feat of modern ingenuity that neatly combines some forty AuthaGraphic world maps, the continents and oceans of the world have been reproduced on a 2D rectangular poster map which shows movement in any direction with no dead ends.

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 Dymaxion Map (revealed in 1946).

There are many applications for this world map using the AuthaGraph projection method. For example, the size and shape of the ozone hole above Antarctica can easily be grasped, and it becomes visually clear why it’s necessary to fly from Tokyo to Brazil via Houston!

As this is a method of projecting a sphere onto a rectangle, its use isn’t limited to depicting coastlines. Taking continental drift for instance, the 600 million year history of continent movements can be expressed with AuthaGraph. India, for example, can be seen breaking away from Madagascar, drifting across the Indian ocean, and colliding with Eurasia to form the Himalayas. Such geological themes can be visually expressed and easily understood.

By its very nature, the spherical world we inhabit has no dead ends. As ancient peoples believed the world existed on an infinite plane, so a sphere and an infinite plane are geometrically very similar. Through tiling or tessellation, Narukawa reproduced an endless world map in 2D as faithfully as possible to the original sphere. Using this as a base, a variety of other maps with different themes can be created.

Taking world history as yet another example, it is possible to plot historical events. During the Age of Discovery beginning in 1475, many adventurers took to the seas. In search of India, Colombus went west and Vasco da Gama east. Using AuthaGraph, the routes they took can be drawn on a single map. It is possible to show how Magellan and Elcano made their circumnavigations, and even how Captain Cook made three trips around the world.

Narukawa’s innovative idea allows us to visualize the world in new ways.

    I recommend the authagraph maps as a new and more geometrically based view of the world. Two maps arrived as ordered and in very quick time and perfect condition.

    I have used a Peter's projection in my classroom for years. This map is a wonderful addition because it keeps the more accurate area but adds the different orientation to show the oceans more accurately too. Very useful to shift world views. The paper and ink used is gorgeous!
