Kavrayskiy VII

Classifications

pseudocylindric

Graticule

Meridians: Central meridian is a straight line 1/√3 as long as the equator. Other meridians are equally spaced elliptic arcs concave toward the central meridian. 120°th meridians are circular arcs.
Parallels: Equally spaced straight parallel lines. Perpendicular to the central meridian.
Poles: Lines half as long as the equator.
Symmetry: About the central meridian and the equator.

Scale

Scale is correct along the 35°31′N/S parallels. Constant along any given latitude; same for the latitude of opposite sign.

Distortion

Free of distortion at 35°31′N/S on the central meridian. Distortion is moderate and balanced throughout the tropics as well as the central meridian up until the arctic. Other regions are dominated by angular deformation.

Similar projections

Natural Earth projection is very similar up to the arctic circle, but is compressed vertically beyond that.

Origin

Presented by Vladimir Vladomirivich Kavrayskiy in 1939.
