Eckert IV equal-area projection

The Eckert IV projection, presented by the German cartographer Max Eckert-Greiffendorff in 1906, is a pseudo-cylindrical equal-area projection. Central meridian and all parallels are straight lines; other meridians are equally spaced elliptical arcs. The scale is true along latitude 40°30’.

kf[lon0/]scale or Kf[lon0/]width

The projection is set with kf or Kf. The central meridian is set with the optional lon0, and the figure size is set with scale or width.
