True scale at latitudes 3.6° and 86.4° N. at central meridian
None at latitudes 3.6° and 86.4° N. at central meridian
An oblique Hammer projection centered at latitude 45° N. and longitude 10° E. and bounded by an ellipse having an axis ratio of 1.75 to 1 instead of 2 to 1, after the vertical coordinates are expanded and the horizontal coordinates are contracted
Whole-world maps showing continents grouped near the center
Presented by William A. Briesemeister of the American Geographical Society in 1953
Hammer (Elliptical), the normal aspect of the Briesemeister, but having an axis ratio of 2 to 1
Nordic, by John Bartholomew, is the same as the Briesemeister projection, except that the axis ratio is 2 to 1 and the central meridian is 0°.
