Note

This projection method, referenced by EPSG as "Oblique Stereographic", is for example used for the Netherlands "Amersfoort / RD New" projected CRS. It gives different results than the :ref:stere method in the non-polar cases (i.e. the oblique and equatorial case).

Required Parameters

• None

Optional Parameters

• +lat_0=<value>: Latitude of origin.
• +lon_0=<value>: Central meridian.
• +k=<value>: Scale factor.
• +x_0=<value>: False easting.
• +y_0=<value>: False northing.
• +ellps=<value>: Ellipsoid used.
• +R=<value>: Radius of the projection sphere.
