GPS and GIS are airport codes for Baltra Airport (GPS) in Ecuador and Gisborne Airport (GIS) in New Zealand. So how far apart are they as the crow flies and as a person might travel?
The FreeMapTools.com How far is it between? can find the answer. The crow would travel some 6300 miles, but the human would have a hard time figuring a path (as did the tool). Better known and more populated places are more likely to have travel distances. Omaha to Beijing is 6500 miles direct and 10,600 miles via modern travel options.
