as these are claims you can’t observe them, you have to rely on the baseline that the claiming country provides/defines and extend it by the buffer that is claimed.

Please notice there is a difference in saying mapping something is a piece of cake, and saying it is possible to punctually verify it on the ground. While it is probably not possible to survey all borders on all points, the opposite construct that it is never possible isn’t true either. 

Cheers, Martin
