Area Control Centers (ARTCC) worldwide
 

I know some countries have their airspace divided among more than one ARTCC (for example, Mexico has Merida, Mexico, Monterrey and Mazatlan centers). Other countries share a single control center (such as Costa Rica, El Salvador and the rest of central america). There are also centers that control the airspace above international waters (such as "oceanic" centers). Is there such a thing as a map of the world that depicts the boundaries of those Area Control Centers?.
