Putniṇš P1´




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


Nowhere true.


Free of distortion nowhere. Distortion is moderate and somewhat biased toward flation along equator. Polar regions are inflated and balanced between flation and angular deformation. Remainder of map is dominated by angular deformation.

Similar projections

Identical to Wagner VI but scaled down somewhat for true area.
Similar to Robinson, but scaled up somewhat and slightly shorter pole lines.
Practically identical to Kavrayskiy VII stretched horizontally and compressed vertically.
