Each sheet measures 33×40 cm and, with a border of 2 cm, the complete map measures 202×124 cm. All sheets span a longitude of 60 degrees; the first row of 6 sheets cover latitudes 80°N to 56°N, the second row cover 56°N to 16°S and the third row cover 16°S to 66°S: this latitude division is not symmetric with respect to the equator thus ...
Boundary is a circle. All parallels and meridians are circular arcs. Usually clipped near 80°N/S. Standard world projection of the NGS in 1922–1988. c. 150: Equidistant conic = simple conic: Conic Equidistant Based on Ptolemy's 1st Projection Distances along meridians are conserved, as is distance along one or two standard parallels.

The Universal Transverse Mercator (UTM) is a map projection system for assigning coordinates to locations on the surface of the Earth.Like the traditional method of latitude and longitude, it is a horizontal position representation, which means it ignores altitude and treats the earth surface as a perfect ellipsoid.
The Gall–Peters projection of the world map. The Gall–Peters projection is a rectangular, equal-area map projection.Like all equal-area projections, it distorts most shapes.
The Hereford Mappa Mundi, about 1300, Hereford Cathedral, England. A mappa mundi (Latin [ˈmappa ˈmʊndiː]; plural = mappae mundi; French: mappemonde; Middle English: mappemond) is any medieval European map of the world.
The World Geodetic System (WGS) is a standard used in cartography, geodesy, and satellite navigation including GPS.The current version, WGS 84, defines an Earth-centered, Earth-fixed coordinate system and a geodetic datum, and also describes the associated Earth Gravitational Model (EGM) and World Magnetic Model (WMM).
The maturation of complex analysis led to general techniques for conformal mapping, where points of a flat surface are handled as numbers on the complex plane.While working at the United States Coast and Geodetic Survey, the American philosopher Charles Sanders Peirce published his projection in 1879, [2] having been inspired by H. A. Schwarz's 1869 conformal transformation of a circle onto a ...
Español: Mapa mundial de migraciones humanas, con el polo norte como centro. Africa es el punto de partida, leyéndose desde la parte superior izquierda hasta América del Sur en el extremo derecho. Los patrones de migración estan basados en estudios del ADN mitocondrial (matrilinear). Los números representan miles de años.
