[OSRS-PROJ] PROJ 4.4.3 - about epsg...

Fri Apr 20 14:33:41 EDT 2001

Thanks for the 4.4.3 update Frank !

I have not compiled it yet but already have a question about the epsg file
you created so couragously...

I do understand the conversion was far from trivial and surely you can not
be 100% sure about the accuracy of all of the parameters in there.

I checked the epsg file and for the Netherlands coordinate system i find
that the datum shift is missing there.

Now how can we contribut to the quality of the epsg parameters if a user
like me finds one that can be improved ?
Should we manually update it in the file or should we file a bug report so
you can improve the batch procedure used to generate the file ?
I can easily fix it here in my own copy but i wonder how i can share the fix
with other proj users.

Otherwise the update looks very promising, i'll be compiling it to a DLL and
testing the 7 paramer shift for amersfoort in a few weeks...
