Answer 1

The Greek invented latitude and longitude. Someone devised a concept of using a reference system based on the shape of the Earth, with the coordinates (latitude, longitude) expressed as degrees.

In the 3rd century BC Erathosthenes proposed a system of latitude and longitude for a map.

The following century (2nd century BC) Hipparchus was the first to use the above system to uniquely specify certain places on th Earth.

Latitude and longitude have been used for centuries for navigation, but the modern system we use today was standardized in the 18th century. The modern concept of latitude and longitude as we know it today was refined by the English mathematician and astronomer Sir George Airy in the mid-19th century.
