Country borders redrawn in Google Maps

Inside Costa Rica points to a recent alteration in the border between Costa Rica and Nicaragua in Google Maps.

The earlier version  labelled the long-disputed Calero Island as Nicaraguan. Some sources claim this mapping ‘error’ led directly to the Nicaraguan occupation of the territory last year. In the newly amended version the border is further North.

Here’s a before and after:

Following this I went back to check the inaccurate Germany-Netherlands border I mentioned last month. This mistake took the water in the harbour at Eimden, a German seaport, and handed it to the Dutch. Turns out that’s been corrected too, in as much as it stops at the edge of the Ems estuary now, and isn’t shown crossing water at all.

Google's Germany-Netherlands border fail removed

Inside Costa Rica  suggest Google’s Central American border problem was triggered by a change in the course of a river.  I wonder if there’s a wider issue with the reliability of boundaries crossing water in the application ?

    Interesting point as a basis for modern colonialism and occupation … could it really be that simple, or Machiavellian?
