Kavrayskiy VII projection explained

The Kavrayskiy VII projection is a map projection invented by Soviet cartographer Vladimir V. Kavrayskiy in 1939 for use as a general-purpose pseudocylindrical projection. Like the Robinson projection, it is a compromise intended to produce good-quality maps with low distortion overall. It scores well in that respect compared to other popular projections, such as the Winkel tripel, despite straight, evenly spaced parallels and a simple formulation. Regardless, it has not been widely used outside the former Soviet Union.

The projection is defined as

\begin x &= \frac \sqrt \\ y &= \varphi\end

where

λ

is the longitude, and

\varphi

is the latitude in radians.
