BTW, won't the bays be self closing during buffer creation (if the
mouth is less than the offset)?
Not really, depending on the size you still get a kind of kink in the
border where cutting short the bay would otherwise give a straight

Well, this part is done:

2. Note the activity required to increase the accuracy (reefs, bay closure)
I've already added some notes

Hi,
finally I got the process sorted out to generate a border from
natural=coastline, natural=reef and the baseline segments. The resulting
osm-file can be found at [1].
Using the dataset I also updated the picture from the post below to show
the differences [2]. It doesn't look that bad
My inclination is..
1. Document accurately the process you have used
2. Note the activity required to increase the accuracy (reefs, bay closure)
3. Upload the borders currently there (things aren't working properly
right now).
4. Work to increase the accuracy.
5. Update the borders

If I understand correctly, the differences should only correspond to
the amount that our coastline differs from the low water mark? Are we
missing parts of the true coastline, is our coastline just inaccurate
do you think?
Well, to me there

It has also been pointed out that having the two inner poly's of the

border of the poly incomplete is causing mapnik and nominatim to think
that both territories are in NSW.

probably a couple of bits I'll go back to and touch up, but otherwise
looking good.
Yes, I think now all land borders are completely mapped. Nice piece of work.
So, what's next to

I've recently used Quantum GIS (QGIS) to create a region about my GPS
routes so as to capture the fuel stops (for example, within 10km of my
chosen path). I would think if someone could establish the coastline as a
perimeter, then it
Hey Michael, Thanks - that made for interesting reading on a subject I knew so
little about. And I agree with you, that the best course of action is to obtain
the data officially. But in the event of failure/refusal, I'm happy to help
out. BTW, in QGIS it's Vector / Geoprocessing Tools /
