We did a GNS import of place names in Ireland at at time when very few
place names were already mapped and the map was full of emptiness. It
worked well for us, since the de-duplication task wasn't that bad and
it created reference points for future mapping. It is certainly true
that accuracy is poor - off by 2km in many cases. But in a
from-scratch mapping effort it's easier to re-spot these than it is to
create brand new nodes, and even the baseline is better than nothing.

I'd be a little more wary of importing such data into a well-mapped area.
