Eckert III projection

From Wiki.GIS.com

The Eckert III projection is 'flat-polar" world map projection developed by Max Eckert, a German professor, and published in 1906 as one of 6 world map projections. This design is sometimes mistaken for the projection of Ortelius's oval map, which lacks constant scale along parallels and thus is not pseudocylindrical. Characteristics of the Eckert III projection include the following:^[1]

• equally spaced parallels
• a straight central meridian
• a standard line
• poles are flat; half as long as the Equator
