Latitude and Longitude
This article, published in the National Atlas, explains what latitude and longitude are and how they are used to define a location on Earth. It discusses Earth as a sphere and points out that latitude values are counted from the equator (0 degrees) to the poles (90 degrees) and that longitude lines divide the Earth equally into 360 degrees from east to west. Other topics include subdivision of degrees into minutes and seconds, and definitions of some commonly used terms. Links to additional information on related topics are included.
