It was never easy to reach an unidentified destination before google maps came in picture. Google map is the most beautiful example of coordinate geometry.
It covers almost every nook and corner of this whole world and makes them reachable any time. What made it possible ? Its not only google.
It was never possible to map any place without coordination of all the countries. Satelites help our smart phones to find our way and these phones are very smart to read human gesture in peculiar way. I would say that after the god and teacher, the best guide of a person right now is google map. Lol !
