Geocart menu class: Cylindric
Meridians: Equally spaced straight parallel lines 0.42 as long as the Equator.
Parallels: Unequally spaced straight lines, farthest apart near the Equator, perpendicular to meridians
Poles: Straight lines equal in length to the Equator
Symmetry: About any meridian or the Equator
True along latitudes 30° N. and S. Too small along the Equator but too large at the Equator along meridians
Increases with distance from the Equator in the direction of parallels and decreases in the direction of meridians to maintain equal area
Same scale at the parallel of opposite sign
Same as the Lambert Cylindrical Equal-Area projection except for horizontal compression and vertical expansion to achieve no distortion at latitudes 30° N. and S. instead of at the Equator
Equivalent to a projection of the globe using parallel lines of projection onto a cylinder secant at 30° N. and S.

Gall Orthographic by James Gall in 1855 (Standard parallels: 45° N. and S.)

Peters by Arno Peters in 1967 (Standard parallels: approximately 45° N. and S., thus essentially identical with the Gall Orthographic)
