The Cylindrical Equal Area projection is suited for equal-area mapping of regions that are predominately bordering the Equator. There is shape distortion but no area distortion in this projection, and shape distortion in the polar regions is extreme. This projection was presented by Johann Heinrich Lambert in 1772, thus it is also known as the Lambert Cylindrical Equal Area projection.
Straight parallel lines that are equally spaced and 0.32 the length of the Equator.
Straight lines that are unequally spaced and farthest apart near the Equator, perpendicular to meridians.
See Meridians and Parallels. Poles are straight lines the same length as the Equator. Symmetry is present about any meridian or the Equator.
Scale is true along the Equator. Equal area is maintained by scale increasing with distance from Equator in direction of parallels and scale decreasing in direction of meridians. Same scale at the parallel of opposite sign.
Equal area mapping of regions predominately bordering the Equator.
