The Gleason Map

The “Gleason Map” is a map with the azimuthal equidistant projection, centered on the north pole. The Gleason Map is not a scaled-down figure of the Earth, but it is merely a projection of the actual, spherical shape of the Earth, like every other map.

Alexander Gleason —the creator of the map— claimed that the map depicts the shape of the ‘flat Earth’. The majority of the flat-Earth communities adopt this map as ‘the flat-Earth map.’ They are wrong. The map is merely a projection of the spherical shape of the Earth, just like every other map types.

Gleason could claim it is the map of ‘flat-Earth’, but his explanation written in his patent for the map is contradictory:

“The extorsion of the map from that of a globe consists, mainly in the straightening out of the meridian lines allowing each to retain their original value from Greenwich, the equator to the two poles.” —US Patent No. 497,917 by Alexander Gleason

From the registered patent, he never mentioned that the Earth is flat. On the contrary, he said that he made the map from a globe, which explains how a north-pole centered azimuthal equidistant map is designed.
