Werner projection
The Werner projection is a pseudoconic equal-area map projection sometimes called the Stab-Werner or Stabius-Werner projection. Like other heart-shaped projections, it is also categorized as cordiform. Stab-Werner refers to two originators: Johannes Werner, a parish priest in Nuremberg, refined and promoted this projection that had been developed earlier by Johannes Stabius of Vienna around 1500.
The projection is a limiting form of the Bonne projection, having its standard parallel at one of the poles. Distances along each parallel and along the central meridian are correct, as are all distances from the north pole.
