Check the article > https://en.wikipedia.org/wiki/Internal_waters > Speaking of maritime boundaries and bays and estuaries, the Rio de la Plata estuary between Argentina and Uruguay is currently modeled in OSM as *inside* the coastline. If you look at the OSM default carto layer at zoom 5 and lower, where inland waterbodies are not rendered, Montevideo and Buenos Aires appear to be landlocked inland cities, which doesn't look right.[1] (See the attached image.) The coastline there follows the UNCLOS claimed baseline which isn't right because UNCLOS allows countries to specify a baseline separate from the coastline that encloses parts of the sea/ocean (thereby making those parts internal waters of the country) when it meets certain geometric conditions. I think the coastline between Argentina and Uruguay should include most of the Rio. If we follow the practice of mapping the coastline along the claimed baseline like in the Rio de la Plata elsewhere in the world, then the Gulf of Sidra in Libya[1] would be considered as an inland waterbody, which does not make sense. Note that the United States have protested as excessive both the claimed baseline of Libya in the Gulf of Sidra (this resulted in the Gulf of Sidra incident in 1981) and the joint claimed baseline of Argentina and Uruguay in the Rio de la Plata.
