Latitude and Longitude Introduction
A system based on Degrees used
in navigation of the globe. Latitude and longitude are a
coordinate system used to locate points on the Earth’s
surface. If a pilot or a ship's captain wants to specify
position on a map, these are the "coordinates" they
would use.
The values of
latitude and longitude for a particular position are
calculated using a set of imaginary lines covering the
Earths surface.
These are two angles, measured in degrees, "minutes of arc" and "seconds of arc." These are denoted by the symbols (°,',") e.g. 35° 43' 9" means an angle of 35 degrees, 43 minutes and 9 seconds. A degree contains 60 minutes of arc and a minute contains 60 seconds of arc.
