Eckert VI




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


True along latitudes 49°16′N and S. Constant along any given latitude; same for the latitude of opposite sign.


Free of distortion only at latitudes 49°16N and S. At the central meridian.

Some recent use for climatic maps by U.S. Publishers.
Presented by Max Eckert (1868-1938) of Germany in 1906.

Similar projections

Eckert V projection has meridians positioned identically, but parallels are equally spaced.
Wagner I projection (1932) is almost identical to Eckert VI, but Wagner I uses only part of the sinusoidal curve.
Kavrayskiy Vl projection (1936) is identical to Wagner I. Werenskiold II projection (1944) is the same as Wagner I, except for scale.
McBryde-Thomas flat-pole sinusoidal uses the full sinusoid and is equal-area, but the poles are one-third the length of the equator.
