Wagner II

Classifications

pseudocylindric

Graticule

Meridians: Central meridian is a straight line half as long as the equator. Other meridians are equally spaced portions of sinusoids concave toward the central meridian.
Parallels: Unequally spaced straight parallel lines. Perpendicular to the central meridian.
Poles: Lines half as long as the equator.
Symmetry: About the central meridian or the equator.

Scale

Constant along any given latitude; same for the latitude of opposite sign.

Distortion

Free of distortion nowhere. Distortion is not as extreme near outer meridians at high latitudes as it is on pointed polar pseudocylindric projections, but there is considerable distortion throughout polar regions.

Similar projections

Eckert V is very close but scaled slightly smaller.
