Explanation:
The only way to find the exact, mathematically accurate location of a place on Earth, is by determine the exact latitude and longitude of the place.
For example, the island of Manhattan, in New York City, is located at 40.754932 latitude, and -73.984016 longitude. These values are what is known as the geographical coordinates of the Island. These coordinates can be put in any geographical software, and the exact location of Manhattan will come up.
