Description

World projected conformally onto an icosahedral arrangement to yield nearly minimal incisions into landmasses.

Classifications

Conformal
Polyhedral

Graticule

Meridians: Complex curves except for the edges and central meridian of each facet
Parallels: Complex curves except for straight edge at base of each facet

Distortion

No distortion at the centroid of each face. Maximum distortion at the corners.

Origin

Mathematical work on conformal projections for regular polyhedra largely originated with Oscar S. Adams from 1925 and onward. L.P. Lee greatly expanded upon and regularized the mathematics in 1976. This arrangement is by Daniel “daan” Strebe in 2019.
