Latitude is angular distance measured north and south of the Equator. The Equator is 0 degrees. As you go north of the equator the Latitude increases all the way up to 90 degrees at the north pole. If you go south of the equator, the Latitude increases all the way up to 90 degrees at the south pole.
There are also 180 degrees of longitude to the west of the Prime Meridian. Western longitudes are often expressed as negative values, particularly in computer applications. One degree of longitude at the Equator also corresponds to 111 Km (111,319.9 m).
