Latitude and Longitude:: Finding Locations On Planet Earth

Latitude lines run east-west and measure locations as degrees north or south of the equator. Longitude lines begin at the prime meridian and measure locations as degrees east or west. By combining a latitude and longitude coordinate, any location on Earth can be precisely pinpointed. For example, a coordinate of 15°S, 105°W refers to a point 15 degrees south of the equator and 105 degrees west of the prime meridian.

Latitude and Longitude:

Finding Locations on
Planet Earth.
Latitude lines run east/west but they measure
north or south of the equator (0°) splitting the
earth into the Northern Hemisphere and
Southern Hemisphere.
Latitude

Lines of
latitude are
numbered from
0° at the equator
to 90° N at the
North Pole.

Lines of latitude are numbered


from 0° at the equator to 90° S at the
South Pole.

The North Pole
is at 90° N 45° N is the

The equator is north of the

is neither north
nor south. It is
at the center
between north

Lines of longitude are numbered east from

Longitude
Lines of longitude begin
at the Prime Meridian.

Prime Meridian
The Prime Meridian (0°) splits the earth into the
Western Hemisphere and Eastern Hemisphere.

Places located east of the Prime Meridian have an


east longitude (E) address. Places located west of the
Prime Meridian have a west longitude (W) address.
Any location north of the equator is a NORTH LATITUDE
Any location south of the equator is a SOUTH LATITUDE
Any location west of the prime meridian is a WEST LONGITUDE
Any location east of the prime meridian is an EAST LONGITUDE
By combining latitude and
longitude, any location can be
pinpointed

Each box on this map is 15°. With that in mind how can we identify specific locations
(red dots)? Remember, write latitude first!
What are the coordinates of location......A
What are the coordinates of location......B
What are the coordinates of location......C
But what about location D ? It’s in the middle of a box. What do we do now?
Here are some things to remember:
> Latitude is written first and must
always include N (north) or S (south)
of the equator.

>Longitude is written next and must


always include E (east) or W (west)
of the prime meridian.
