List of map projections—Wikipedia, the free encyclopedia

 

This list/table provides an overview of the most significant map projections, including those listed on Wikipedia. It is sortable by the main fields. Inclusion in the table is subjective, as there is no definitive list of map projections.

Projection Images Type Properties Creator Year Notes
Equirectangular
Equirectangular projection SW.jpg Cylindrical Compromise Marinus of Tyre 120 (c.) Simplest geometry; distances along meridians are conserved.

Mercator
Mercator projection SW.jpg Cylindrical Conformal Gerardus Mercator 1569 Lines of constant bearing (rhumb lines) are straight, aiding navigation. Areas inflate with latitude, becoming so extreme that the map cannot show the poles.

Collignon Collignon projection SW.jpg Pseudocylindrical Equal-Area Édouard Collignon 1865 (c.) Depending on configuration, the projection also may map the sphere to a single diamond or a pair of squares.

Lambert azimuthal equal-area Lambert azimuthal equal-area projection SW.jpg Azimuthal Equal-Area Johann Heinrich Lambert 1772 The straight-line distance between the central point on the map to any other map is the same as the straight-line 3D distance through the globe between the two points.
Stereographic Stereographic projection SW.JPG Azimuthal Conformal Hipparchos(deployed) 200 BC (c.) Map is infinite in extent with outer hemisphere inflating severely, so it is often used as two hemispheres. Maps all small circles to circles, which is useful for planetary mapping to preserve the shapes of craters.
