van der Grinten III



Meridians: Central meridian is straight. Other meridians are circular, equally spaced along the equator but unequally spaced along other parallels and concave toward the central meridian.
Parallels: Straight lines.
Poles: Points.
Symmetry: About the central meridian or the equator.


True along the equator. Increases rapidly with distance from the equator.


Great distortion of area near the poles.

Other features

The world is enclosed in a circle. Spacing of parallels along the central meridian is the same as that for Van der Crinten I.


World maps, but rarely.

Similar projections

Van der Grinten I has curved parallels.
“The Times”, by Moir, has nearly elliptical meridians, but straight parallels are spaced like those of the Gall projection.
