Near the end of July/beginning of november, someone (gnis user) changed all the Louisiana ADM2s into ADMDs.
This seems like a massive loss of information. As I understand it, ADMDs are basically deprecated because they don't contribute hierarchy information like ADM1-ADM4 do.
Do you have an example for Puerto Rico? The ADM1 have been added or cleanedup. The counties are now adm1, otherwise there is a dummy adm1 'PR' that does not make much sense.
My mistake. PR data looks good. I used to have a hack on my end to skip the old admin1 codes because they were all 00. PR data is much cleaner now. Thanks much.
