Folks,
spatialreference.org (which is a great service) reports the proj4 text for
for example 3067 without the towgs84 parameters when they are all zeros. IMHO
they should be reported as proj4 nowadays requires them to work correctly.
The proj4 epsg file contains them. The zeros are needed also in the proj4text
field of spatial_ref_sys table of PostGIS.
Omitting towgs parameters (even when they are zeros) causes confusion. See
for example
http://comments.gmane.org/gmane.comp.gis.postgis/24549 (the comment This is
bewildering. I found this by mere chance).
and I also experienced the same today with PostGIS converting from 2393 to
3067.
Ari,
This is most likely simply a matter of the proj version being used on
spatialreference.org not being up-to-date. spatialreference.org is entirely
run by volunteers (mostly Chris), and he hasn't had any bandwidth to dedicate
to it lately. If you are interested in picking things up, please join the
MetaCRS (cc'd) list, which is the group that currently oversees it. I'm sure
Chris would have no problem handing you the keys to the VM it lives on to
update things and add the features you need.
