[gdal-dev] Update of EPSG database to v8.4

[Yann Chemin]

Hi Even,

I would be interested to include it. But I see that the 1Mb
uncompressed text is an issue.

If it was OK for the additional Mb in the source code,
what would be the place to look into gdal code to create the patch needed?

Thanks,
Yann

PS: did not copy other lists as I am not a member, registered to proj
ML today though.
