Polar Stereographic (Variant C)
The Polar Stereographic projection somewhat resembles other polar azimuthal projections, with straight radiating meridians and concentric circles for parallels. In Variant C, we define the latitude of a standard parallel along which the scale is unity; the intersection of this parallel with the longitude of origin is the false origin, at which grid coordinate values are defined.
The "Polar Stereographic Variant C" projection has the following parameters:
