Latitude and Longitude

1. Latitude and Longitude

2. Cardinal Directions North West East South

3. Intermediate Directions North West North East South West South East

4. Intermediate Directions • Always say North or South first. • Example: Say “North East” not “East North”

5. Secondary Intermediate • NNW – north north west • NNE – north north east • ENE – east north east • ESE – east south east • SSE – south south east • SSW – south south west • WSW – west south west • WNW – west north west

6. Compass Rose

7. Latitude • Latitude: distance north or south of the equator. • The lines are called parallels • 0° is the equator • 0° to 90 ° N – equator to north pole • 0° to 90 ° S – equator to south pole

8. Latitude • Arctic Circle — 66 ° N • Tropic of Cancer — 23.5 ° N • Tropic of Capricorn — 23.5 ° S • Antarctic Circle — 66 ° S

9. Longitude • Longitude: distance east or west of the prime meridian. • The lines are called meridians • Prime Meridian - 0 ° longitude • Unlike latitude, which has the equator as a natural starting position, there is no natural starting position for longitude. Therefore, a reference meridian had to be chosen. • Runs through Greenwich, England • Runs from 0 ° (Prime Meridian) to 180 ° (International Date Line)

10. International Date Line • The International Date Line (IDL) is an imaginary line on the surface of the Earth opposite the Prime Meridian which offsets the date as one travels east or west across it. • The date to the east of the line is one day earlier than that to the west of the line.
