Hammer projection is suited for thematic maps of the world, such as land cover.

Construction

Modified Azimuth

Property

Equal-area

Meridians

The central meridian is half as long as the Equator and a straight line. Others are curved and concave toward the central meridian and unequally spaced.

Parallels

With the exception of the Equator, all parallels are complex curves that have a concave shape toward the nearest pole.

Graticule spacing

Only the Equator and central meridian are straight lines.

Linear scale

Scale lessens along the Equator and central meridian as proximity to the origin grows.

Uses

World maps only.
