Parameters

Note

All parameters are optional for the projection.

+W=<value>

The factor +W is the ratio of the difference in longitude from the central meridian to the a circular meridian to 90. +W must be a positive value.

Defaults to 2.0

+lon_0=<value>

Longitude of projection center.

Defaults to 0.0.

+lat_1=<value>

First standard parallel.

Defaults to 0.0.

+ellps=<value>

The name of a built-in ellipsoid definition.

See Ellipsoids for more information, or execute proj -le for a list of built-in ellipsoid names.

Defaults to “GRS80”.

+R=<value>

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

See Ellipsoid size parameters for more information.

+x_0=<value>

False easting.

Defaults to 0.0.

+y_0=<value>

False northing.

Defaults to 0.0.
