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

• kf or Kf: Sets the projection type.

• lon0: Sets the central meridian [Optional].
