ummmm, could you explain that more? inner UTM terms may be interesting
on the summary page, but beyond that the user just cares about "zone 12
North" + datum choice(s). For UTM the projection will always be TM of
course, and other terms will be fixed based on the zone..

glad to hear it.

there is the option to abandon it and tell users to look it up in the
EPSG file instead, but then they have to know what they are looking for
as County names will not be there.

I think there are enough twists and turns in it that get_stp.c would
have to be rewritten in Python & parse the FIPS.code etc files directly.
Looking at the C code, it doesn't seem so bad.
