Behrmann projection of the world.
The Behrmann cylindrical equal-area projection with Tissot's indicatrices of deformation

The Behrmann projection is a cylindrical map projection. It was created by Walter Behrmann in 1910. This is an orthographic projection onto a cylinder secant at the 30° parallels. As a member of the Cylindrical equal-area projection family, it shares many characteristics with for example the Lambert cylindrical equal-area projection and the Gall orthographic projection, which have standard parallels of 0 and 45 degrees respectively. It is equal-area, but distortion of shape increases with distance from the standard parallels. Scale is true along the standard parallels and constant between two parallels equidistant from the Equator. This projection is not equidistant.
