Longitude and Latitude

Longitude and latitude are measured in degrees and minutes. 

Longitude is measured West of the Prime Meridian, which passes through Greenwich, England at 0o .  The International Date Line goes through the Pacific Ocean at 180 o longitude. Lines of longitude are also known as meridians.

Latitude is measured North and South of the Equator (0°), which separates the northern and southern hemispheres. 

Standard map notation example: 

Guatemala City            14° 37' N     90° 31' W

Extra Credit: Find and know about these famous latitudes:
The Tropic of Cancer is located at 23°30' N and is the northern boundary of the tropics. The Tropic of Capricorn is located at 23°30' S, and is the southern boundary of the tropics. They mark the farthest point north or south at which the sun can be seen directly overhead at noon. The Arctic Circle is located at 66 1/2°N and marks the northernmost point at which the sun can be seen at the winter solstice (about Dec. 21) and the southernmost point of the northern polar regions at which the midnight sun is visible.
