A few additional notes on the stereographics:
1. +proj=sterea and +proj=rouss compare quite closely and the former
could be used by those with current libraries to handle Polish grids
their accuracy needs are not in the cm. range.
2. +proj=stere (of GCTP fame) produces larger differences and also has
slightly larger scale errors. If one is not replicating existing
using +proj=stere or UPS, I would recommend +proj=sterea for oblique/
3. While doing the documentation for the stereographic it was readily
that, softwarewise, sterea should be part of the PJ_stere.c file.
Thus the next
release will be missing PJ_sterea.c. Lest anyone panic, the
entry will still be there and all operations will match previous
polar aspect is chosen in sterea it will resort to the same
in stere (which does not go through conformal sphere).
