Flat Earth Map - Gleason's New Standard Map Of The World - Large 24 x 36 1892

Product Information

From the map’s patent, we know the author was aware and in full knowledge that the map was just a projection of the spherical Earth, contradictory to the claims in his book. When the center point is the north pole, φ 0 equals π / 2 {\displaystyle \pi /2} and λ 0 is arbitrary, so it is most convenient to assign it the value of 0. This assignment significantly simplifies the equations for ρ u and θ to: 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 The so-called “Gleason Map” is an old map published in the 19th century. The author was a flat-Earther who claimed the map as the “flat Earth map.” In reality, the map is just a normal azimuthal equidistant map centered on the North Pole.

While it may have been used by ancient Egyptians for star maps in some holy books, [1] the earliest text describing the azimuthal equidistant projection is an 11th-century work by al-Biruni. [2] The azimuthal equidistant projection is an azimuthal map projection. It has the useful properties that all points on the map are at proportionally correct distances from the center point, and that all points on the map are at the correct azimuth (direction) from the center point. A useful application for this type of projection is a polar projection which shows all meridians (lines of longitude) as straight, with distances from the pole represented correctly. The flag of the United Nations contains an example of a polar azimuthal equidistant projection. With the circumference of the Earth being approximately 40,000km (24,855mi), the maximum distance that can be displayed on an azimuthal equidistant projection map is half the circumference, or about 20,000km (12,427mi). For distances less than 10,000km (6,214mi) distortions are minimal. For distances 10,000–15,000km (6,214–9,321mi) the distortions are moderate. Distances greater than 15,000km (9,321mi) are severely distorted.David A.

I usually work on general relativity and cosmology. I have always loved geometrical things. As a kid I was fascinated by map projections. When I was 14, I made a painted globe of Mars based on a flat Mercator Mars map by the astronomer E. M. Antoniadi. Since becoming an emeritus professor at Princeton, I have fondly returned to some of my childhood interests. Azimuthal equidistant map projection An azimuthal equidistant projection about the North Pole extending all the way to the South Pole. An azimuthal equidistant projection about the South Pole extending all the way to the North Pole. Emblem of the United Nations containing a polar azimuthal equidistant projection. The relationship between the coordinates ( θ, ρ) of the point on the globe, and its latitude and longitude coordinates ( φ, λ) is given by the equations:
