Aspect

An oblique, transversal aspect of Mollweide.

Graticule

Meridians: Complex curves.
Parallels: Complex curves.
Poles: Points.
Symmetry: Along the central and horizontal axes.

Distortion

Undistorted only at two points: One on the southeastern coast of the USA, and one in the Mediterranean, when oriented as specified by the projection’s author. Angular deformation is generally low throughout the center of the map, with its most extremes at the left/right edges.

Usage

The projection intends to show the Atlantic and environs with low distortion. Antarctica also fares well, as does the arctic regions.

Similar projections

The projection is the Mollweide in transversal aspect, centered on 45°N, 30°W, and scaled so that the outer ellipse has different proportions.

Origin

First published by John Bartholomew in 1948 in Regional Atlas.
