As I am working on my map of Washington, I have found that the Puget Sound is not showing up as ocean. Do you know any tricks to specify an area of the map as ocean? The NHD data only includes ground water features.
This is the metadata for the file that should do the trick: http://www.ecy.wa.gov/services/gis/data/shore/shore.htm
and it should be available at: http://www.ecy.wa.gov/services/gis/data/data.htm#shore
My internet isn't really working so I can't actually check and see.
Thanks Oz, I'll check it out and see how well it works.
