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

Projection String

+proj=stere +lat_0=90 +latTs=75
Copy

Note: This projection method gives different results than the :ref:sterea method in the non-polar cases (i.e. the oblique and equatorial case). The later projection method is the one referenced by EPSG as "Oblique Stereographic".

Required Parameters

• None

Optional Parameters

• +lat_0=<value>: Latitude of origin.
• +latTs=<value>: Latitude where scale is not distorted.
• +k_0=<value>: Scale factor.
• +lon_0=<value>: Central meridian.
• +ellps=<value>: Ellipsoid used.
• +R=<value>: Radius of the projection sphere.
• +x_0=<value>: False easting.
• +y_0=<value>: False northing.
