Latitude and Longitude

• Latitude, which gives the location of a place north or south of the equator, is expressed by angular measurements ranging from 0° at the equator to 90° at the poles.

Latitude Lines • Imaginary lines that run east to west around the globe • Measure degrees north and south of the Equator http: //academic. brooklyn. cuny. edu/geology/leveson/core/linksa/longlat. html

• Each degree of latitude and longitude is divided into 60 minutes, and each minute divided into 60 seconds, thereby allowing the assignment of a precise numerical location to any place on earth.

Longitude Lines • Imaginary lines that run from the north pole to the south pole • Measure degrees east and west of the Prime Meridian http: //academic. brooklyn. cuny. edu/geology/leveson/core/linksa/longlat. html

• Lines of longitude run north and south along the surface of the earth. Mapmakers think of the earth as a huge globe that is divided into 360 equal slices. The lines between the slices on the outside of the globe are called meridians. Meridians are the main lines of longitude on maps.

The Prime Meridian The imaginary line at 0° longitude http: //worldatlas. c om/aatlas/newart/ locator/meridian. h tm

• Although the equator was an obvious choice as the prime parallel, being the largest, no one meridian was uniquely qualified as prime. Until a single prime meridian could be agreed upon, each nation was free to choose its own, with the result that many 19 th -century maps of the world lacked a standardized grid.

The problem was resolved in 1884, when an international prime meridian, passing through London's Greenwich Observatory, was officially designated.

Helpful Hint: • If you stretch your body out as LONG as you can make it- this is a longitude line…

How to Read Latitude and Longitude If you know the latitude and longitude of a place, put one finger on the line of longitude and another on the line of latitude. Bring your fingers together until they meet. http: //academic. brooklyn. cuny. edu/geology/leveson/core/linksa/longlat. html

Calculating Latitude and Longitude • Always calculate Latitude First – North and South of the Equator • Then calculate Longitude – East and West of the Prime Meridian
