I’ve come to notice that certain “cities” in countries like Sweden and Vietnam will have a couple sets of letters next to them. Take the “N” in Älvdalen N, for example:
Contrasting it with Älvdalen S:
Other letters for Sweden I’ve found are V, SV and Ö, which makes me think these are cardinal directions. I’ve looked online but it doesn’t seem like the counties of Sweden, or their subdivisions, are called Älvdalen South and Älvdalen North, for example.
In fact, some of the few mentions of “Älvdalen S” I found on Google seem to be directly related with the way Google Maps itself classifies the country geographically.
For Vietnam I’ve found “tx.”:
Would anyone else know more about these letter/location combinations, maybe in other countries? I’ll also tag @CoolCrab directly, as the top contributor for Sweden and an active forum member, I’m hoping you might be able to enlighten me.
