Yes, but I hope we'll fix that quickly.

I was thinking of doing this not for oceans (because we'd have to spread
nodes over 70% of the world which would, to a superficial analysis, make
the ocean tiles "non-empty" because they have a node on them) but, in a
later version of the software, for larger inland areas like very large
lakes or forests. But that would first need some changes in
close-areas.pl to work with these as well, currently it does only

I too think it is important that everbody is able to make changes but
until now thought it sufficient that everybody can edit the coastline,
and hoped that Martijn would complete the index file to reliably cover
the whole world. Do you have issues with the index file in Europe?
