The Eckert V projection is a pseudocylindrical projection that is neither conformal nor equal area. This projection was presented by Max Eckert in 1906.
Meridians in this projection are equally spaced sinusoids, concave toward the central meridian. The central meridian is a straight line half as long as the Equator. Parallels are represented by equally spaced straight parallel lines that are perpendicular to the central meridian. Poles are represented by lines half as long as the Equator. This projection is symmetrical about the central meridian or the Equator. Scale is true along latitudes 37°55' N and S, and constant along any given latitude.

NOTE: Only a spherical form of this projection is used. The semi-major axis of the ellipsoid (sphere) is used for forward and inverse projection from grid to geodetic coordinates within the system wherein this projection is incorporated.
