I. JUST THE FACTS
Crisscrossing lines called latitude and longitude lines form an imaginary grid that precisely defines every location on the globe. The markings of latitude lines are circles around the globe which run parallel to each other. They are often called parallels of latitude for this reason. Latitude comes from the Latin word meaning "width". On flat maps, parallels are straight lines that run the width of the page, thus their name of latitude.
Latitude is a measurement of how far north or south from the equator a position on a globe or map is. The equator is the natural north/south dividing point of the earth. Thus, latitude has a physical starting point, the equator which is 0°. The points farthest north and south of the equator are called the North Pole and South Pole. The latitude of the North Pole is 90° N and the latitude of the South Pole is 90° S.
Latitude is measured in degrees (or hours), minutes, and seconds. Just like time, there are 60 minutes in 1 degree (hour) of latitude and 60 seconds in 1 minute of latitude. Latitude measurements are written in the form degrees:minutes:seconds.
Longitude is an angular measurement of how far east or west
one is of the Prime Meridian (i.e. zero degrees longitude).
Unlike the equator, the zero of latitude, the Prime Meridian has no
physical basis and its location was based on politics. It is a much harder
problem to determine ones longitude than ones latitude. Latitude i
can easily be obtained by measuring the angle of the sun at
mid day. In fact the conquest of the longitude problem is the
subject of a recent book: Longitude: The True Story of a
Lone Genius Who Solved the Greatest Scientific Problem of
His Time by Dava Sobel.
Longitude is also divided into degrees, minutes, and seconds and
extends from the Prime Meridian to 180° W and to
180° E. Note: look on a globe
180° W and 180° E are the same place!
