Behrmann Equal Area Cylindrical

Description

This projection is an equal-area cylindrical projection suitable for world mapping.

Projection method

Cylindrical—standard parallels are at 30° N and S (a case of Cylindrical Equal Area).

Lines of contact

The two parallels at 30° N and S.

Linear graticules

Meridians and parallels are linear.

Properties

Shape

Shape distortion is minimized near the standard parallels. Shapes are distorted north–south between the standard parallels and distorted east–west above 30° N and below 30° S.

Area

Area is maintained.

Direction

Directions are generally distorted.

Distance

Distances are generally distorted except along the equator.

Limitations

Useful for world maps only.

Uses and applications

Only useful for world maps.

Parameters

Desktop

• False Easting
