Central Meridian: Straight line half the length of the Equator.
Meridians: Sine curves (60º segments).
Parallels: Unequally spaced straight lines.
Poles: Straight lines half the length of the Equator.
Symmetry: About the Equator and the central meridian.
This is an equal-area projection. Scale is constant along any parallel or pair of equidistant parallels. This projection is neither conformal nor equidistant.
There are no standard parallels for this projection.
This projection was described by V. V. Kavraisky in 1936. It is also called the Wagner I, for Karlheinz Wagner, who described it in 1932.
