Meridians: Central meridian is a straight line 40.5% as long as the equator. Meridians are equally spaced semiellipses intersecting at the poles and concave toward the central meridian.
Parallels: Unequally spaced straight parallel lines, farthest apart near the equator; spacing changes gradually. Perpendicular to the central meridian.
Poles: Points.
Symmetry: About the central meridian and the equator.

Scale

True along the equator.
