Navigation: A Closer Look

Recap:

• A coordinate system is used to locate your position on earth.

• The science of locating ones position is called navigation.

• This system is based on the angular measurement from the equator and prime meridian (the two main reference lines for measuring latitude and longitude).

A Closer LOOK

• Since they are angular measurements, they break down into smaller increments called minutes

• 1 degree of latitude or longitude = 60 minutes (‘)

• 1 minute of latitude or longitude can break down even further into seconds (‘’)

The Degree Breakdown

• 1°=60’• 1’=60’’

• We use this to pinpoint an exact location• See New York Map
