An approximation of the AuthaGraph projection. AuthaGraph is an approximately equal-area world map projection invented by Japanese architect Hajime Narukawa [1] in 1999. [2] The map is made by equally dividing a spherical surface into 96 triangles, transferring it to a tetrahedron while maintaining area proportions, and unfolding it in the form of a rectangle: it is a polyhedral map projection.
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.
The United Nations geoscheme is a system which divides 248 countries and territories in the world into six continental regions, 22 geographical subregions, and two intermediary regions. [1] It was devised by the United Nations Statistics Division (UNSD) based on the M49 coding classification . [ 2 ]
Division of the world into the sheets of the map series. The World Map 1:2,500,000 (Russian: Карта Мира 1:2,500,000) is an internationally standardized and edited map series. The Russian term Карта Мира or in transcription Karta Mira is now commonly used to describe this series, even outside the Soviet Union or Russia.
Equirectangular projection of the world; the standard parallel is the equator (plate carrée projection). Equirectangular projection with Tissot's indicatrix of deformation and with the standard parallels lying on the equator True-colour satellite image of Earth in equirectangular projection Height map of planet Earth at 2km per pixel, including oceanic bathymetry information, normalized as 8 ...
[1] [2] The size of the emblem on the flag is one half the width of the flag itself. The flag proportions of the aspect ratio of the flag height to its width, are equal 2:3, 3:5 or to the same proportions as the national flag of any country in which the UN flag is flown. [2] White and blue are the official colours of the United Nations. The ...
Bonne projection of the world, standard parallel at 45°N. Bonne projection with Tissot's indicatrix of deformation. World map by Bernard Sylvanus, 1511. The Bonne projection is a pseudoconical equal-area map projection, sometimes called a dépôt de la guerre, [1]: 104 modified Flamsteed, [1]: 104 or a Sylvanus projection.
A world map is a map of Earth. World map may also refer to: International Map of the World, an international project to produce topographic maps of terrestrial portions of Earth at the one to one million scale; Overworld, an area within a video game that interconnects all its levels or locations in
