Description

Cylindric projection with an appearance similar to the Mercator, but shows the poles.

Classifications

cylindric
compromise

Graticule

Meridians: Straight, evenly spaced, 92.2% the length of the parallels.
Parallels: Straight, with spacing increasing with latitude.

Scale

Scale is correct along the equator and constant along all parallels.

Distortion

Free of distortion nowhere. The map’s distortion is predominately in the form of inflation except in the tropics, where angular deformation is greater.

Origin

Presented by N.A. Urmayev in 1947, from his system that forces a chosen scale factor along three different parallels.
