   en.wikipedia.org/wiki/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.

3. Google Earth - Wikipedia

   en.wikipedia.org/wiki/Google_Earth

   Google Earth. Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery. The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering ...

   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).

6. Geographic information system - Wikipedia

   en.wikipedia.org/wiki/Geographic_Information_System

   A traditional topographic map rendered in 3D. Traditional maps are abstractions of the real world, a sampling of important elements portrayed on a sheet of paper with symbols to represent physical objects. People who use maps must interpret these symbols. Topographic maps show the shape of land surface with contour lines or with shaded relief.

7. Dymaxion map - Wikipedia

   The Dymaxion mapor Fuller mapis a projectionof a world maponto the surface of an icosahedron, which can be unfolded and flattened to two dimensions. The flat map is heavily interruptedin order to preserve shapes and sizes. The projection was invented by Buckminster Fuller. The March 1, 1943, edition of Lifemagazineincluded a photographic essay ...
