Latitude and
Longitude
 Latitude
is lines of position that run parallel to the
equator. These lines are measured in degrees north
or south of the equator. A typical reading would be
N 45 30’. Each degree is exactly 60 miles. A minute
of latitude is equal to a mile. That’s were the
expression a mile a minute comes from.
Longitude is lines called meridians that slice up
the earth from east to west. The prime meridian runs
through Greenwich England and has a value of 0
degrees. All other meridians have a value of east or
west of the prime meridian. A typical reading would
be west 100 degrees 30 minutes. Here the minutes are
not a mile as the distance increases as one
approaches the equator.
The latitude and longitude lines are always in black
on your chart. You must line up a red line on the
Charting Pal with a black line on your chart. When
navigating, the meridians are preferable as they
always point true north. |
