I wonder, can all 3 variants of the EPSG (OGP) stereographic projections be
calculated with (lib)proj's stere?
EPSG coordinate operation method 9810:
Polar Stereographic (variant A)
For Projected Coordinate Reference System: WGS 84 / UPS North
EPSG coordinate operation method 9829:
Polar Stereographic (variant B)
For Projected Coordinate Reference System: WGS 84 / Australian Antarctic
Polar Stereographic
EPSG coordinate operation method 9830:
Polar Stereographic (variant C)
For Projected Coordinate Reference System: Petrels 1972 / Terre Adelie Polar
Stereographic
Especially variants B and C still puzzle me a bit - in the sense of how to
do it with PROJ?
Probably not possible; the PROJ file "epsg" tells me for instance:
# Petrels 1972 / Terre Adelie Polar Stereographic
# Unable to translate coordinate system into PROJ.4 format.
Formulae and numerical examples can be found in the EPSG/OGP Guidance Note
7-2.
