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.
Between Madagascar and Los Romeros Isles there is an extremely violent current of the sea in the East and West direction such that sailing therein is of great difficulty to go from the one to the others according to the testimony of M. Polo, the Venetian, Bk.3, chapt.40; hence necessarily these coasts cannot be very distant from Madagascar so ...
The zonal maps should be viewed as a kind of teaching aid – easily reproduced and designed to reinforce the idea of the Earth's sphericity and climate zones. T-O maps were designed to schematically illustrate the three land masses of the world as it was known to the Romans and their medieval European heirs.
Modified transverse Mercator, a variation of UTM used in Canada with zones spaced 3° of longitude apart as opposed to UTM's 6°. Transverse Mercator projection, the map projection used by UTM. Universal Polar Stereographic coordinate system, used at the North and South poles. Open Location Code, a hierarchical zoned system
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
A T and O map or O–T or T–O map (orbis terrarum, orb or circle of the lands; with the letter T inside an O), also known as an Isidoran map, is a type of early world map that represents world geography as first described by the 7th-century scholar Isidore of Seville (c. 560–636) in his De Natura Rerum and later his Etymologiae (c. 625) [1]
The making of the map was a major undertaking and the map took several years to complete. The map was not created by Fra Mauro alone, but by a team of cartographers, artists, and copyists led by him and using some of the most expensive techniques available at the time. The price of the map would have been about an average copyist's annual ...
For maps of smaller regions, an ellipsoidal model must be chosen if greater accuracy is required; see next section. The spherical form of the transverse Mercator projection was one of the seven new projections presented, in 1772, by Johann Heinrich Lambert.
