[Imports] Boundary of Tonga

[Rafael Avila Coya]

Hi,

Tonga is not the only country with no borders in the Pacific. I see that
Tuvalu is still very poorly mapped.

When I started to map in the area, I noticed that Tuvalu, Tonga and
Kiribati nodes were misplaced. Tuvalu and Tonga nodes were completely
out of where they should be, and Kiribati, a country formed by three
island groups (the Gilberts ( http://osm.org/go/6orRd ), the Phoenix (
http://osm.org/go/FXGPh ) and the Line ( http://osm.org/go/QKpmq-- )
islands, from W to E) separated thousands of kilometers from each other,
had its node over the Gilberts (the far West of the country). I just
placed them where they are. Maybe not the perfect place, but much better
than before.

Solomon islands ( http://osm.org/go/vwdey-- ) didn't even have a border,
nor even its name! I draw its borders as they are now, not following any
rule, just as a provisional solution. For example, this islands (
http://osm.org/go/vyghqV-- ) belong to Solomon Islands, but as they are,
they "don't belong to any country". It needs somebody with skills to
have its borders drawn properly. I placed its node also in a more or
less centric position.

You can see many other countries, like Vanuatu, Samoa and others with no
see borders around.

I doubts that any other solution than using a country node could apply
to a country like, for example, Kiribati. If you use the largest
conterminous of Kiribati, that would place the name of the country
around Kiritimati ( http://osm.org/go/QgRG4Kt- ), the biggest coral
atoll in the world, just on the East end of the country! And using the
coast line could placed it in a non-convenient place too, as there are
some islands located far to the south in the Line group... Very tricky.

Some users (mainly Quarksteilchen and me (edvac)) are coordinating
efforts to map the very scattered 33 islands of Kiribati though the
wiki: https://wiki.openstreetmap.org/wiki/Kiribati. Just in case you
want to contact us before making any import.

Cheers,

Rafael Ávila Coya.
