World map. 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 earliest known world maps date to classical antiquity, the oldest examples of the 6th to 5th centuries BCE still based on the flat Earth paradigm. World maps assuming a spherical Earth first appear in the Hellenistic period. The developments of Greek geography during this time, notably by Eratosthenes and Posidonius culminated in the Roman ...
Gall–Peters projection. The Gall–Peters projection is a rectangular, equal-area map projection. Like all equal-area projections, it distorts most shapes. It is a cylindrical equal-area projection with latitudes 45° north and south as the regions on the map that have no distortion. The projection is named after James Gall and Arno Peters .
A family of map projections that includes as special cases Mollweide projection, Collignon projection, and the various cylindrical equal-area projections. Depending on configuration, the projection also may map the sphere to a single diamond or a pair of squares. Hybrid of Collignon + Lambert cylindrical equal-area.
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] The creators note that "the assignment of ...
The International Map of the World (IMW), also known as the Millionth Map of the World, [ 1] after its scale of 1:1 000 000, was a project to create a complete map of the world according to internationally agreed standards. [ 7] Roads were depicted in red, towns and railways were depicted in black, and the labels were written in the Roman alphabet.
Global Map. Global Map is a set of digital maps that accurately cover the whole globe to express the status of global environment. It is developed through the cooperation of National Geospatial Information Authorities (NGIAs) in the world. An initiative to develop Global Map under international cooperation, the Global Mapping Project, was ...
Mercator's 1569 map was a large planisphere, [ 3] i.e. a projection of the spherical Earth onto the plane. It was printed in eighteen separate sheets from copper plates engraved by Mercator himself. [ 4] 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 ...
