Hi Ralf:

About the nodes Bopolu A, B, C..., I wouldn't condense them into one,
as doing so we are loosing information on different settlements, or
parts of the same whole settlement.

I would better leave them as such, and maybe (that should be
discussed) tag them as place=neighbourhood, leaving the GNS Bopolu one
in more or less the centroid of all A, B, C... nodes, or creating one.
The tag for that node would have to be discussed too. I would bet for
place=villace...

Cheers,

Rafael.
