Where can I get polygons (multipolygons) of all countries of the world including the territorial waters of the countries?

OpenStreetmap displays these areas but I can't find an extract of this subset of the OSM data.

  • is there a subset of OSM data available, just containing the territories (incl. water territories) of a country as multipolygons ?
  • or, can I find this set of polygons somewhere else?

    I think you are looking for a way to download OSM. Look in this thread or google it

    OK, I was not detailed enough. I know that OSM has this data but I'm looking for an extract of the OSM data which just contains the boundaries of a country and the territorial waters. I do not want to download the complete world wide dataset just to get the boundaries. (changed the question accordingly)

  • try in geofabrik.de, but I'm not sure they have it.

The country boundaries including the territorial waters are available in the OSM data set. I found a site where these country shapes can be downloaded: https://wambachers-osm.website/boundaries/


Take a look at the Global Administrative Areas dataset at http://www.gadm.org, it contains at least the boundaries, though I am not so sure about the territorial waters part
