Does this offline reverse geo coding calculation require downloading the
global admin_level=2 boundary data? Is it a reasonable amount of data?
Does it take 0.1ms per node, or can several highway segments be checked in
the same calculation?
I imagine the same calculation could be used for other default
calculations, like the default language format,
Or it could be used to display certain features differently in different
countries: e.g. don’t use a cross symbol for hospitals in Saudi Arabia.
For the USA, how quickly can you reverse geocode admin_levels 2, 4, 6 and 8
for a road? (National, State, County and Municipal)
