Meridians: Equally spaced elliptical curves converging at the poles.
Parallels: Straight lines.
Symmetry: About the Equator and central meridian.
This projection is equal-area. Scale is constant along any parallel or pair of parallels equidistant from the Equator. This projection is neither equidistant nor conformal.
There is no standard parallel for this projection.
This projection was first described in 1643 by Georges Fournier. This is actually his second projection, the Fournier II.
