Classifications
pseudocylindric
equal-area
Graticule
Meridians: Sinusoids.
Parallels: Straight parallel lines.
Poles: Lines half the length of the equator.
Symmetry: About the central meridian and the equator.
Scale
Correct along the equator.
Distortion
Free of distortion along the equator. Angular deformation increases away from the equator.
Similar projections
Similar to the Nell projection, but in this case it is the x coordinate that gets averaged from the sinusoidal and the Lambert cylindric equal-area, with y coordinates adjusted to retain equivalence.
Limiting case of the sinucyli projection.
Origin
Presented by Ernst Hermann Heinrich Hammer, 1900.
