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

Product Information

Azimuthal equidistant projection maps can also be useful to show ranges of missiles, as demonstrated by the map centered on North Korea showing the country's missile range. As Gleason’s map is centered on the north pole, the edges indicate the south pole. Experts told Reuters that Antarctica is clearly visible as the white ring on the perimeter of the map, contrary to claims by social media users that the continent is not shown. 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:

Gleason might have claimed that the map is the “flat-Earth map” but his explanation written in his patent for the map is contradictory: 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:Scientific American is part of Springer Nature, which owns or has commercial relations with thousands of scientific publications (many of them can be found at www.springernature.com/us). Scientific American maintains a strict policy of editorial independence in reporting developments in science to our readers. A disadvantage of the new map is that you can’t see all of the Earth’s surface at once, but remember this is true for the globe as well. Our map is actually more like the globe in this respect than other flat maps. To see all of the globe, you have to rotate it; to see all of the new map, you simply have to flip it over, as you can see below 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 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 Thanks for reading Scientific American.

One can’t make everything perfect. The Mercator map has a boundary cut error: one makes a cut of 180 degrees along the meridian of the international date line from pole to pole and unrolls the Earth’s surface, thus putting Hawaii on the far-left side of the map and Japan on the far-right side of the map creating an additional distance error in the process. A pilot flying a great circle route straight from New York to Tokyo passes over northern Alaska. His route looks bent on a Mercator map—a flexion error. North America is lopsided to the north: Canada is bigger than it should be, and Mexico is too small. All these errors are important. Ignoring one of them can lead you to bad-looking maps no one would prefer.Anyone who cares can make observations (of the moon’s phases, of time zones, of constellations) that can all be understood in the context of a round earth but would be hard to explain otherwise without separate reasons for each observation,” he added, VERDICT The Winkle tripel is a map to hang on your wall. Ours is a more accurate one you can hold in your hand. This double-sided map has a Goldberg-Gott error score of only 0.881 versus 4.563 for the Winkel tripel. It beats the Winkel tripel in each of the six error terms! It has zero boundary cut error since continents and oceans are continuous over the circular edge. It has a remarkable property no single-sided flat map possesses: distance errors between pairs of points (such as cities) are bounded, being off by only at most plus or minus 22.2 percent. In the Mercator and Winkel tripel projections, distance errors blow up as one approaches the poles and boundary cuts.

Steffen also said that individuals can perform a similar experiment using geometry and Polaris, or the north star, as a function of latitude. 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. References 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.
