# Equal Earth¶

New in version 5.2.0.

 Classification Pseudo cylindrical Available forms Forward and inverse, spherical and ellipsoidal projection Defined area Global Alias eqearth Domain 2D Input type Geodetic coordinates Output type Projected coordinates

proj-string: +proj=eqearth

The Equal Earth projection is intended for making world maps. Equal Earth is a projection inspired by the Robinson projection, but unlike the Robinson projection retains the relative size of areas. The projection was designed in 2018 by Bojan Savric, Tom Patterson and Bernhard Jenny [Savric2018].

## Usage¶

The Equal Earth projection has no special options. Here is an example of an forward projection on a sphere with a radius of 1 m:

\$ echo 122 47 | src/proj +proj=eqearth +R=1
1.55        0.89


## Parameters¶

Note

All parameters for the projection are optional.

+lon_0=<value>

Longitude of projection center.

Defaults to 0.0.

+ellps=<value>

See proj -le for a list of available ellipsoids.

Defaults to “GRS80”.

+R=<value>

Radius of the sphere given in meters. If used in conjunction with +ellps +R takes precedence.

+x_0=<value>

False easting.

Defaults to 0.0.

+y_0=<value>

False northing.

Defaults to 0.0.
