Looks close to the output from proj4 above.
Thoughts?
Dylan,
Thanks for showing me how to check the calculations. I get identical
results using my copies of cs2cs and postgis, on both systems.
I conclude from this that the effect of adding @null to the definition
of NAD27 in pj_datums.c is that it somehow eliminates the error message
but doesn't render the results incorrect. I don't pretend to understand
why this is so, but I'm happy to proceed with this configuration.
Peter,
Adding @null to the end essentially means that if all else fails, just
apply a null transformation and don't complain if the null file isn't
found.
Best regards,
--
