I'm trying to familiarize myself with proj.
I'm trying to use cs2cs to do a datum shift where a 7-parm
transformation is used. I want it to do the shift in
"proj -ld" seems to provide a possible example. The listing
for ire65 has example towgs84 settings.
Ellipse: modif_airy (sic)
What do I need to specify for cs2cs for both directions
of the transform?
seems like a resonable start. Where does the +towgs84 argument go?
How do things change in the reverse direction?
Thanks for your assistance,
