I encourage you to start a listing of trac pages with hints and tips for
particular countries / national mapping systems, and then add pages off
that where applicable.  I would discourage starting with a list of many
countries where only a few have actual content as that discourages people
from digging through.

Keep in mind that some information belongs instead in the FAQ:


and some information on general PROJ parameters belongs in:


We also have the geotiff projection list which I hope will become part of
a more general MetaCRS resource which will apply to PROJ.4, proj4js, CS-Map
and other packages.

I would note that a "national info registry" that only ended up with 4-5
nations listed could still be pretty useful, so don't get hung up on whether
the material is comprehensive.  And part of the rationale for moving to Trac
for PROJ.4 was to encourage user community updates to the web site.  So just
dive in!
