This equal-area projection has true scale along the central meridian and all parallels. Equatorial aspect is a Sinusoidal. Polar aspect is a Werner.
Pseudo conic. Parallels of latitude are equally spaced concentric circular arcs, marked true to scale for meridians.
A single standard parallel with no distortion.
The central meridian.
Usually limited to maps of continents or smaller regions. Distortion pattern makes other equal-area projections preferable.
Used during the 19th and early 20th centuries for atlas maps of Asia, Australia, Europe, and North America. Replaced with the Lambert Azimuthal Equal Area projection for continental mapping by Rand McNally & Co. and Hammond, Inc.
Large-scale topographic mapping of France and Ireland, along with Morocco and some other Mediterranean countries (Snyder, 1993).
