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.
