We already have something that can trace water (lakes and rivers, and
coastline also works pretty well) from landsat. Dshpak has a few tools
he's built that we're using for parts of Canada to start mapping some of
our million lakes, including one very nice iteration of the tool that
allows you to mark the lakes in JOSM (with the help of wms/ymms) with a
node, and then it reads the file and traces the lake the node is located
in. He's waiting to get svn access so he can put it up for others to
use, but a few of us Canadian mappers have got copies from him and tried
it out. I believe it was also used to trace the coastline for Vancouver
Island which worked pretty well.
And srw also has a river-tracer that has been used a bit for some rivers.
