What are latitude and longitude ?
A. Early geographers divided the earth into a grid to assist in agreeing where the various continents were. The earth is divided into lines of longitude that run from the north pole to the south pole. There are 360 lines of longitude. Lines of latitude are parallel to each other and are drawn below as concentric circles from the equator at the center of the globe to north and south poles. Each degree of latitude and longitude is further divided into 60 minutes and for GPS use into hundredths of a minute. One minute of latitude equals one nautical mile. Key West Florida lies at latitude 24 degrees 34 minutes north and longitude 81 degrees 48 minutes west.
