AW: [Qgis-user] why is EPSG:2180 not recognised?

[Richard Duivenvoorde]

Hi,
I've got sqliteadmin (http://sqliteadmin.orbmu2k.de/) here, and it seems 
pretty trivial to update the database srs.db with that tool...

Though it might not be that trivial?
Looking at a freshly downloaded epsg file of the proj lib, I see
	# WGS 72
	<4322> +proj=longlat +ellps=WGS72 +no_defs  <>
The same holds true for 4322, 4622 and 4625

Can somebody explain to me then why it should be jean-claude's version? 
Or in other words, if the latest proj doesn't have it, what/who should 
be the authorative source in this case then?
The srs.db. is nothing more then the parameters used by proj isn't it? 
Or am I missing something here?

3328 - 3335 are indeed available in latest proj (and not in srs.db), so 
it should be easy to add them.
same for 3120
same for 3066

If I can count on some help with projection-specific questions, I can 
make it a part of my 'release-team' work? I will add it to the 
release-checklist in wiki then.

Is it ok to update it for every release, or for every 'bug' people find 
in it?

Regards,

Richard Duivenvoorde
