    en.wikipedia.org/wiki/List_of_map_projections

    List of map projections This is a summary of map projections that have articles of their own on Wikipedia or that are otherwise notable. Because there is no limit to the number of possible map projections, [1] there can be no comprehensive list.

  3. AuthaGraph projection - Wikipedia

    en.wikipedia.org/wiki/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. The map substantially preserves sizes and ...

  4. World map - Wikipedia

    en.wikipedia.org/wiki/World_map

    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.

  5. Gall–Peters projection - Wikipedia

    en.wikipedia.org/wiki/Gall–Peters_projection

    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.

  6. Mercator projection - Wikipedia

    en.wikipedia.org/wiki/Mercator_projection

    Proportions of distorted and real size. Note that the map is multiply interrupted along political lines. 360° cylindrical projections: Equirectangular, Miller, Mercator, and true cylindrical. As with all map projections, the shapes or sizes are distortions of the true layout of the Earth's surface.

  7. Map projection - Wikipedia

    en.wikipedia.org/wiki/Map_projection

    Reference maps of the world often appear on compromise projections. Due to distortions inherent in any map of the world, the choice of projection becomes largely one of aesthetics. Thematic maps normally require an equal area projection so that phenomena per unit area are shown in correct proportion. [41]

  8. Web Mercator projection - Wikipedia

    en.wikipedia.org/wiki/Web_Mercator_projection

    Web Mercator, Google Web Mercator, Spherical Mercator, WGS 84 Web Mercator[1] or WGS 84/Pseudo-Mercator is a variant of the Mercator map projection and is the de facto standard for Web mapping applications.

  9. Equal-area projection - Wikipedia

    en.wikipedia.org/wiki/Equal-area_projection

    Equal-area projection. In cartography, an equivalent, authalic, or equal-area projection is a map projection that preserves relative area measure between any and all map regions. Equivalent projections are widely used for thematic maps showing scenario distribution such as population, farmland distribution, forested areas, and so forth, because ...
