[OSM-dev] Finding water vs. land

my renderer downloads data for tiles (currently in the 0.1° grid) and
then renderes these.
This works fine, except for coastlines, where I have two problems:
* The coastlines are just open lines, but I need closed areas for
* When I download data in the middle of the ocean, no coastline crosses
the tile and I do not know that the current tile must be filled
completely with water
That there is some coastline data for mapnik, but I don't quite
understand how that process works.
So how would I:
* figure out that a certain area is water-covered?
* get a complete, closed coast line (possible for the entire world?)
and both best via some HTTP request :)
All the best,
