One Instagram user ( here) shared a TikTok video which tries to challenge the fact that that Gleason’s map is a projection of the earth as a globe. Distances between cities are measured by simply stretching a string between them; if they are in opposite hemispheres, the string simply stretches across the equator at the edge of the map. 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. A point on the globe is chosen as "the center" in the sense that mapped distances and azimuth directions from that point to any other point will be correct.

NASA has published images of the earth from space, noting the “ancient Greeks believed the Earth was round and calculated its circumference with remarkable accuracy” ( here). A projection of a person on a page is also flat (see Jeff Brown’s ‘Flat Stanley’ character), but people aren’t flat,” Bennett said. 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 thin box could hold flat double-sided maps of all the major objects in the solar system, or a stack of Earth maps giving physical and political data. e. the other antenna being communicated with) and uses the map to determine the azimuth angle needed to point the operator's antenna. Before photographic proof was possible, Eratosthenes measured the earth’s shadow cast by a stick during the summer solstice to calculate the circumference of the earth ( here. Azimuthal equidistant map projection An azimuthal equidistant projection about the North Pole extending all the way to the South Pole. Some social media users are saying that Alexander Gleason’s 19th Century “New Standard Map of the World” is proof that the earth is flat and that Antarctica is not a continent but an ice ring that circles the earth’s edges.

North America is lopsided to the north: Canada is bigger than it should be, and Mexico is too small. 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. 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. Greenland appears as large as South America even though it covers only one seventh the area on the globe.The shadow [earth] casts on the moon during an eclipse is round, regardless of where the moon is in the sky,” Steffen said. This type of projection allows the operator to easily determine in which direction to point their directional antenna. The answer is one in which the North Pole appears at the center of the north side of the phonograph record, with longitude lines spreading out equally from it where the scale on each longitude line is uniform, and similarly for the south side.

In May 1893, Gleason patented the invention of the “New Standard Map of the World”, a projection of the earth centered on the north pole, which can be found ( here). That point, ( φ 0, λ 0), will project to the center of a circular projection, with φ referring to latitude and λ referring to longitude. GeographicLib provides a class for performing azimuthal equidistant projections centered at any point on the ellipsoid. 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).In France and Russia this projection is named "Postel projection" after Guillaume Postel, who used it for a map in 1581. 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.

It has straight pole lines top and bottom with bulging left and right margins marking its 180 degree boundary cut in the middle of the Pacific.

The Global Positioning System (GPS) technology they power also demonstrates that the world is round. If the azimuthal equidistant projection map is centered about a point whose antipodal point lies on land and the map is extended to the maximum distance of 20,000km (12,427mi) the antipode point smears into a large circle. David Goldhaber-Gordon, a professor of physics at Stanford University, said that while flat maps are convenient, “a flat map of a curved surface must have distortions,” and “different mappings create different distortions. 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. 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.
