I imported some OS OpenData coastline stuff not long after they came
out. I wrote up a wiki page about using the OS OpenData vector stuff
here: http://wiki.openstreetmap.org/wiki/Using_OS_Shapefiles . I expect
there are better ways than this now.
I know that tracing Bing can be better in some places. Where the
coastline is changing quickly, such as parts of the fast-eroding east
coast for example, Bing, being newer, is better in my experience. You
need local knowledge or a survey to establish where the high-water mark
is (where coastline should be placed) from the imagery. Sometimes that
should be part-way up the beach on the strand line but sometimes at the
base of a cliff or seawall.

Looking at the wiki, it seems that Ordnance Survey OpenData includes
high resolution coastline data, much nicer than the PGS data which is
currently used. Is there an established method for using this vector
data? I'm not after a mass import of any kind, but it would be nice to
be able to manually select chunks of it to improve tricky coastline
areas.
Sorry if I'm dragging up an old issue here, I had a quick look around
but couldn't find anything conclusive.
