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.
Longitude is measured from the Prime Meridian (which is the longitude that runs through Greenwich, England), with positive values going east (0 to 180) and negative values going west (0 to -180). So, for example, 65 degrees west longitude, 45 degrees north latitude is -65 degrees longitude, +45 degrees latitude.
