FINDING YOUR WAY

1. Latitude says how far north or south you are: 0° at the Equator, up to 90°N at the North Pole and 90°S at the South Pole. Lines of latitude run across the map.
2. Longitude says how far east or west you are: 0° at Greenwich in London (the Prime Meridian), up to 180°E or 180°W on the other side of the world. Lines of longitude run from pole to pole.
3. A position is written latitude first: New York is about 41°N, 74°W.
4. One degree of latitude is about 111 km. (A degree of longitude is 111 km at the Equator but shrinks towards the poles, where the lines meet.)
5. A bearing is a direction in degrees, clockwise from north: north 000°, east 090°, south 180°, west 270°. North-east is 045°.
6. This flat map stretches the world near the poles, so it is good for reading positions but not for measuring big distances.
