[postgis-users] Looking for world coastline data

[Michael O'Sullivan]

HI all,

I am looking at implementing an "AtSea" query in my application - hence 
I am looking for a basic set of world coastline data.  I imagine a set 
of polygons.  I have found a few commercial datasets which include a lot 
of other data which I am not interested in. Does anyone have any 
pointers to a free (or commercial) set of world coastline data?

cheers,

Michael
