Not long ago, a Nicaraguan military commander caused an international incident by leading his soldiers into Costa Rican territory. He replaced a Costa Rican flag with a Nicaraguan one, too. And according to the commander, this all occurred because of an error on Google Maps. Apparently maps used by both the Nicaraguan and Costa Rican governments agree on the location of a border near San Juan del Norte. Unfortunately, the commander consulted Google Maps, which shows a rather different version of the boundary.
