Central Meridian: Straight line 0.48 as long as the Equator. Other Meridians: Equally spaced elliptical arcs concave toward the central meridian. The eccentricity of each ellipse changes at the Equator. Parallels: Unequally spaced straight parallel lines, perpendicular to the central meridian. Spacing is not symmetrical about the Equator. Poles: The North Pole is a line two-thirds the length of the Equator; the South Pole is a line three-fourths the length of the Equator. Symmetry: About the central meridian but not the Equator.Features
This is an equal-area projection. Scale is true along 40°42'N and 38°27'S, and is constant along any parallel but generally not between pairs of parallels equidistant from the Equator. It is free of distortion only along the central meridian at 40°42'N and 38°27'S. This projection is not conformal or equidistant.Parallels
Because of the asymmetrical nature of this projection, two standard parallels must be specified. The standard parallels are by definition fixed at 40°42'N and 38°27'S.Remarks
This projection was presented by Masataka Hatano in 1972.
