[feature request] Expose the "EPSG Geodetic Parameter Dataset" version

[jmckenna]

• the former epsg.io includes in the footer Powered by EPSG database 11.001 which is very useful to the user
• the current spatialreference.org footer states Built on 2024-04-04 using PROJ 9.4.0
  • could the footer be updated magically to something like Built on 2024-04-04 using PROJ 9.4.0, EPSG v11.004 ?

"magically"? :P What I get from pyproj is in a file like this one: https://crs-explorer.proj.org/metadata.txt There is more information than just the version of EPSG

Do you think there is a better location to put all that information?

Something like "Built on 2024-04-04 using PROJ 9.4.0, Detailed versions here"?

@jjimenezshaw You can extract the information field by field with https://pyproj4.github.io/pyproj/stable/api/database.html#pyproj-database-get-database-metadata

[jmckenna]

How about:

"Built on 2024-04-04 using PROJ 9.4.0 (see here for detailed versions)"

(oops I didn't see Even's response yet)

[jjimenezshaw]

I can extract the information of EPSG version, sure. My point is that there are more DBs, like esri. Should we say only one version? Or give all the information?

[jmckenna]

@jjimenezshaw I prefer less development work ha. So I propose:

"Built on 2024-04-04 using PROJ 9.4.0 (for detailed versions see here)"
