Longitude is the measurement east or west of the prime meridianlongitude is measured by imaginary lines that run around the earth vertically (up and down) and meet at the north and south poles these lines are known as meridians each meridian measures one arcdegree of longitude the distance around the earth measures 360 degrees.
Latitude latitude indicates the location of a place on earth north or south of the equatorlatitude is an angular measurement in degrees (marked with °) ranging from 0° at the equator to 90° at the poles (90° n for the north pole or 90° s for the south pole) degrees of latitude are parallel so the distance between each degree remains almost constant each degree of latitude. Navigation is now carried out with many high-tech improvements like satellites however, for thousands of years people found their way around the globe and made fairly accurate maps using astronomical techniques based on the kinds of principles we have been studying as we have discussed in other units, where you are is described by your latitude and longitude.
