Hi, so I have a problem with making a query that will show me boundaries of Baltic Sea as a polygon/multiplygon, all I could find is a node with some info about Baltic.
This isn’t available, because there are many definitions for it. Then the maintenance of such large areas is a nightmare, and low performance.
You find the definition you want separately. Eg IHO Limits of Oceans and Seas. International Hydrographic Organization, IHO; Sieger, R (2012): Limits of oceans and seas in digitized, machine readable form (has a DOI which you may like if academic)

Okay so what do I do If I want to get data about positions of all wind farms on the Baltic sea ? do I have put approximate coordinates or what ?
perhaps “drawing” with JOSM the area & with the overpass poly option? just as a quick manual no tested example with the data suggested by @Kovoschiz
