Map Projections

Projections at identical scale with maximum angular deformation 
values represented by colors

Angular deformation scale

Map in sinusoidal (Sanson-Flamsteed) projection: equal-area, but only the Equator and central meridian are free of angular deformation

Polyhedral maps are a particular case of interruption. On an unfolded Waterman polyhedron, the gnomonic projection centered on faces is azimuthal, therefore the deformation pattern is radically symmetric.
