Polyconic projection class
Polyconic can refer either to a class of map projections or to a specific projection known less ambiguously as the American polyconic projection. Polyconic as a class refers to those projections whose parallels are all non-concentric circular arcs, except for a straight equator, and the centers of these circles lie along a central axis. This description applies to projections in equatorial aspect.[1]
Polyconic projections
Some of the projections that fall into the polyconic class are:
- American polyconic projection
- Latitudinally equal-differential polyconic projection
- Rectangular polyconic projection
- Van der Grinten projection
A series of polyconic projections, each in a circle, was also presented by Hans Mauer in 1922,[2] who also presented an equal-area polyconic in 1935.[3]:248 Another series by Georgiy Aleksandrovich Ginzburg appeared starting in 1949.[3]:258-262
