What is a projection?

Wagner VII


Parameters: Variant




Meridians: Central meridian is straight and half the length of the equator. Other meridians are curves, unequally spaced along the equator and concave toward the central meridian.
Parallels: Equator is straight. Other parallels are curves, unequally spaced along the central meridian and concave toward the nearest pole.
Poles: Curved lines.
Symmetry: About the central meridian or the equator.


Decreases along the central meridian and the equator with distance from the center of the projection.


Considerable shape distortion in polar areas.

Other features

A modification of the Hammer projection; the poles correspond to the 65th parallels on the Hammer, and meridians are repositioned.
This projection can be considered a specialization of the generalized Wagner.


World maps, such as climatic maps prepared by the U.S. Department of Commerce.

Similar projections

Hammer (elliptical) truncated and otherwise modified for the Wagner VII.
Strebe 1995 has rounder corners.


Presented by Karlheinz Wagner of Germany in 1941.
