Loxodromes or rhumb lines are straight. Used for navigation and regions near equator. Standard for maritime mapping in the 17th and 18th centuries. Much criticism recently. Lambert's Cylindrical Equal Area Meridians are equally spaced Parallels get closer near poles.
Parallels are sines.
True scale at equator. History Invented in 1772 by Johann Heinrich Lambert with along with 6 other projections. Prototype for Behrmann and other modified cylindrical equal-area projections. Neither equal area or conformal. Modified in 20th century by changing standard parallels Miller Cylindrical Projection America's compromise projection 4 proposals with different lat.
