Stereographic¶

Classification	Azimuthal
Available forms	Forward and inverse, spherical and ellipsoidal
Defined area	Global
Alias	stere
Domain	2D
Input type	Geodetic coordinates
Output type	Projected coordinates

Parameters¶

Note

All parameters are optional for the projection.

+lat_0=<value>¶

Latitude of projection center.

Defaults to 0.0.

+lat_ts=<value>¶: Defines the latitude where scale is not distorted. It is only taken into account for Polar Stereographic formulations (+lat_0 = +/- 90 ), and then defaults to the +lat_0 value. If set to a value different from +/- 90, it takes precedence over +k_0 if both options are used together.

+k_0=<value>¶

Scale factor. Determines scale factor used in the projection.

Defaults to 1.0.

+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.
