Without considering the current situation at Hague Intl. Court, the current Chilean sea borders extend up to 200 nautical miles, from the low tide line to the west, following the paralel lines, regarding continental Chile, and up to 350 nautical miles, from said low tide line, in a circle centered at each main island, in the case of Easter Island and Sala y Gomez Islands. Thus, the depiction of the Chilean sea border falls short.

The Peruvian continental sea border depicted on the map does follow the 200 NM criteria, by the paralel lines rule, which is correct, regardless of the current sea border dispute between Chile and Perú (it may change "slightly").

Can this be fixed?

As far as I am aware, Chile does not claim 200 NM of territorial waters. In contrast to Peru, Chile only claims 12 NM of territorial waters, with a 200 NM Exclusive Economic Zone (which is something different). We don't usually map these zones but I suggest you discuss the issue on the Chilean mailing list,

Oh, yep, you're right... sorry!

Didn't know that Perú claims territorial waters so far into the sea. They call it "Mar de Grau". Cool, learned something new :)

Thanks for the help!
