I'm looking for a list of all populated places(not just big cities/ports) on the world that reside on sea/ocean. The list should contain the place name, latitude and longitude. Does something like that exist somewhere?
A bit more details: The reason I'm asking for this is because of my project requirement. I need to build a web service which can let people select a place in a list of all possible places in the world(Listed for example in GeoNames DB) but which are on the sea or ocean. The user then gets meteorological data that is related only to places which are on the sea. Like tides, sea temperatures and other more specific info related to the project. Allowing the user to select a place which is not on the sea would simply make no sense.
