Werner projection
The Werner projection is a pseudoconical equal-area map projection, sometimes called the Stabius-Werner or the Stab-Werner projection. Because it is heart shaped, it is sometimes called a cordiform projection.
Each point is the correct distance from the north pole so the north-south scale is the same everywhere at the central meridian. Away from the central meridian and the north pole, distances and shapes are distorted.
In a sense the Werner projection wraps the east and west parts of a sinusoidal projection around the north pole. The Bonne and Bottomley projections are intermediate between the Bonne and the sinusoidal.
