The two straight-line distances from any point on the map to the two control points are correct. 2021 Gott, Goldberg and Vanderbei’s Azimuthal Equidistant J. Richard Gott, Goldberg and Robert J. Vanderbei: Gott, Goldberg and Vanderbei’s double-sided disk map was designed to minimize all six types of map distortions.
Gerardus Mercator's map of the North Pole from 1595 C.G. Zorgdragers map of the North Pole from 1720. As early as the 16th century, many prominent people correctly believed that the North Pole was in a sea, which in the 19th century was called the Polynya or Open Polar Sea. [7]
Another early example of this system is the world map by ‛Ali b. Ahmad al-Sharafi of Sfax in 1571. [3] The projection appears in many Renaissance maps, and Gerardus Mercator used it for an inset of the north polar regions in sheet 13 and legend 6 of his well-known 1569 map.
In 1569, Mercator announced a new projection by publishing a large world map measuring 202 by 124 cm (80 by 49 in) and printed in eighteen separate sheets. Mercator titled the map Nova et Aucta Orbis Terrae Descriptio ad Usum Navigantium Emendata: "A new and augmented description of Earth corrected for the use of sailors". This title, along ...
The equator is the circle that is equidistant from the North Pole and South Pole. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere. Of the parallels or circles of latitude, it is the longest, and the only 'great circle' (a circle on the surface of the Earth, centered on Earth's center). All the other parallels are ...
A more complete illustrated list of world maps of that time may be compiled from the comprehensive survey of Shirley. Comparisons with his own map show how freely he borrowed from these maps and from his own 1538 world map [34] and his 1541 globe. [citation needed] A 1550 portolan of the eastern Mediterranean showing the high quality of coastal ...
Description: Mercator's 1595 map of the Arctic. Mercator, Gerhard, 1512-1594. "Septentrionalium Terrarum descriptio" [1595]. First state, from his posthumously published atlas, Atlantis pars altera.
The 45th parallel north is often called the halfway point between the equator and the North Pole, but the true halfway point is 16.0 km (9.9 mi) north of it (approximately between 45°08'36" and 45°08'37") because Earth is an oblate spheroid; that is, it bulges at the equator and is flattened at the poles.
