Meridians: Equally spaced straight lines converging at the North Pole.
Parallels: Unequally spaced straight parallel lines, farthest apart near the North Pole, closest near the South Pole
Poles: North Pole is a point, South Pole is a line 1.41 as long as the Equator.
Symmetry: About the central meridian.
This is a novelty projection showing a straight-line, equal-area graticule. Scale is true along the 15º51'N parallel, constant along any parallel, and different for any pair of parallels. Distortion is severe in many regions, and is only absent at 15º51'N on the central meridian. This projection is not conformal or equidistant.
This projection has one standard parallel, which is by definition fixed at 15º51'.
