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
