  2. Mollweide projection - Wikipedia

    en.wikipedia.org/wiki/Mollweide_projection

    The Mollweide is a pseudocylindrical projection in which the equator is represented as a straight horizontal line perpendicular to a central meridian that is one-half the equator's length. The other parallels compress near the poles, while the other meridians are equally spaced at the equator. The meridians at 90 degrees east and west form a ...

  3. List of map projections - Wikipedia

    en.wikipedia.org/wiki/List_of_map_projections

    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.

  4. Sinusoidal projection - Wikipedia

    en.wikipedia.org/wiki/Sinusoidal_projection

    Sinusoidal projection. Sinusoidal projection of the world. The sinusoidal projection is a pseudocylindrical equal-area map projection, sometimes called the Sanson–Flamsteed or the Mercator equal-area projection. Jean Cossin of Dieppe was one of the first mapmakers to use the sinusoidal, using it in a world map in 1570. [1]

  5. Eckert IV projection - Wikipedia

    en.wikipedia.org/wiki/Eckert_IV_projection

    Eckert IV projection with Tissot's indicatrices of distortion. The Eckert IV projection is an equal-area pseudocylindrical map projection. The length of the polar lines is half that of the equator, and lines of longitude are semiellipses, or portions of ellipses. It was first described by Max Eckert in 1906 as one of a series of three pairs of ...

  6. Mercator projection - Wikipedia

    en.wikipedia.org/wiki/Mercator_projection

    The Mercator projection (/ mərˈkeɪtər /) is a conformal cylindrical map projection first presented by Flemish geographer and mapmaker Gerardus Mercator in 1569. In the 18th century, it became the standard map projection for navigation due to its property of representing rhumb lines as straight lines.

  7. Map projection - Wikipedia

    en.wikipedia.org/wiki/Map_projection

    In cartography, a map projection is any of a broad set of transformations employed to represent the curved two-dimensional surface of a globe on a plane. [1][2][3] In a map projection, coordinates, often expressed as latitude and longitude, of locations from the surface of the globe are transformed to coordinates on a plane. [4][5] Projection ...

  8. Robinson projection - Wikipedia

    en.wikipedia.org/wiki/Robinson_projection

    Robinson projection of the world The Robinson projection with Tissot's indicatrix of deformation Map of the world created by the Central Intelligence Agency, with standard parallels 38°N and 38°S. The Robinson projection is a map projection of a world map that shows the entire world at once. It was specifically created in an attempt to find a ...

  9. Cylindrical equal-area projection - Wikipedia

    en.wikipedia.org/wiki/Cylindrical_equal-area...

    The projection: is an equal-area projection, that means any two areas in the map have the same relative size compared to their size on the sphere. The term "normal cylindrical projection" is used to refer to any projection in which meridians are mapped to equally spaced vertical lines and circles of latitude are mapped to horizontal lines (or ...
