if you knew your latitude was 57 and your longitude was 47, then you can look on a map of the earth and see which line is latitude 57. you could then follow latitude line 57 until you hit longitude line 47.this would give you the precisest location of your whereabouts.
so u have a number for latitude and another number for longitude just looked at the map and follow the lined until u meet at where the 2 points connect.
