I'm fine with making the island name a point. It would show up in
POI applications.

Cool,
So, what should be
done for the next release?
- Keep the
natural=land areas - everybody will have to merge each
island to get the proper rendering;
- Transform the
natural=land areas into points - no merging necessary, no
name lost;
- Remove the
natural=land areas - name will be lost for next release (1);
I'm inclided to
implement the second proposition - Easier for me and for
most of the contributors;

1- The name should
be found in both Canvec Island and Named feature
(natural=land areas and place=island points) within the next
year.
I've been taking all three objects and merging them. So the inner
is natural=wood, with name.

Seems to be rendering ok. Childs and Osawa are examples.

You are right :-(
Two solutions are
possible for the next release...
- Convert
natural=land area into point feature - the easy solution
to always keep the name available;
- Associate the
name to the inner component - If it renders properly.
The second one is
much more complex (from my side). Can someone try it and
send me the conclusion?
Daniel
I notice for islands with names the name tag is on the
natural=land.

I wrote "natural=land area features are a duplicate of natural=water inner polygon. It will be removed for the next release. Point features will still be there."
I understand that natural=land has priority in the rendering. Rendering will then "move" any overlapping features "under" the natural=land feature. It means you are better remove natural=land area before importing.
The standard case for an island is
- an inner component of a relation type=multipolygon : natural=water
- a polygon : natural=land
- a polygon : natural=wood
Remove the polygon natural=land and the polygon natural=wood will render properly in the hole created by the inner component of the natural=water multipolygon.

Subject: [Talk-ca] Sinking islands...
I was importing data in the Georgian Bay area and I noticed
something. If an island is natural=land it renders in mapnik as white,
regardless of the outer multipolygon. if you have natrual=wood or
possibly others, it sinks if it's not role=inner.
This is at least what I've observed so far. It's rather hard to figure
out when the mapnik tiles get cached and don't refresh in a timely fashion. :-)
