Latitude and Longitude
■Lines of Latitude and
Longitude are imaginary lines
that encircle the Earth in
either an East- West direction
or in a North-South direction
■Together they form a grid
which can be used to identify
locations on the Earth’s
surface

Latitude and Longitude
■When using these lines to find a
location the coordinates are always
given latitude first and then longitude

Latitude

Latitude
■Latitude is the name for a group of
imaginary lines that run parallel to the
Equator
■The Equator is the 0 degree line and
splits the earth into two equal halves –
northern and southern hemispheres
■Each hemisphere is divided into 90
degrees, from the Equator to the Pole

6. **0
Latitude
■When finding a point in the Northern
hemisphere the latitude is given as (x)
degrees N
■For a point in the Southern
hemisphere the coordinates would be
(x) degrees S

7. **0
Latitude
■Lines of latitude get smaller as they
get further north because the distance
around the Earth decreases
■At the Poles the latitude is 90 degrees
and the circular distance is 0km, each
Pole being just a single point

8. **0
Latitude
■There are several major lines of
Latitude other than the Equator and the
Poles
■They are the Tropic of Cancer, the
Tropic of Capricorn, the Arctic Circle and
the Antarctic Circle

Longitude

10. **0
Longitude
■Lines of longitude run north-south
around the planet
■They begin at the Prime Meridian and
split the Earth into East and West
hemispheres
■There are 180 degrees in each
hemisphere

11. **0
Longitude
■When locating a point in the Eastern
hemisphere the longitude is given as (x)
degrees E
■For a point in the Western hemisphere
the longitude would be (x) degrees W

12. **0
Longitude
■All lines of longitude are the same
length
■There is only one important line of
Longitude other than the Prime Meridian
– the International Date Line
■This is the 180 degree line in both
directions

Finding Locations
■To use latitude and
longitude to find a location
you simply follow the lines
until they meet at the point
you are looking for

Finding Locations
Finding Locations
■The latitude is always the first coordinate
given
■It will be a number between 0 and 90
degrees and will be followed by either an N or
an S, depending on which hemisphere the
location is in
■Longitude is always the second number and
will be between 0 and 180 degrees, followed
by either an E or a W

Finding Locations
Finding Locations
■Not all points are located neatly at the
points where the lines intersect
■To find locations between the points
each degree is split into 60 smaller
sections called minutes
■For example, the coordinates for
Orono are 43 59N 78 36W

Finding Locations
Finding Locations■The coordinates for Orono mean that the
village is located 43 degrees and 59 minutes
north of the Equator and 78 degrees and 36
minutes west of the Prime Meridian
■If you are using a GPS device there will be
an additional set of numbers for each
coordinate, called seconds
■Seconds subdivide the minutes into even
smaller sections and provide additional
accuracy
