LATITUDE & LONGITUDE LINES:

LATITUDE

Lines go east

and west.

LONGITUDE

Lines go north

and south.

used to measure and record

the LATITUDE and

LONGITUDE of a

LOCATION in DEGREES,

SAMPLE ACTIVITY:

PLOT THE POSITIONS OF A FEW

LOCATIONS ON A CHART


The basics of ploting ocean locations the gps latitude longitude

Materials needed for this sample activity:

Copies of Santa Monica Bay

or southern California chart

pencils

Ruler or

straight-edge

Location data

(from GPS)


The basics of ploting ocean locations the gps latitude longitude

STEPS TO FOLLOW IN THIS ACTIVITY:

1- FIND THE LATITUDE LINE AND

DRAW IT IN PLACE USING YOUR

PENCIL AND RULER.

2- FIND THE LONGITUDE LINE AND

DRAW IT IN PLACE USING YOUR

PENCIL AND RULER

3. PLACE AN “X” TO MARK THE

SPOT WHERE LATITUDE AND

LONGITUDE LINES CROSS.

SAMPLE PROBLEM #1:

LOCATE THE SANTA MONICA PIER


The basics of ploting ocean locations the gps latitude longitude

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W


The basics of ploting ocean locations the gps latitude longitude

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W

First, we’ll

draw the

LATITUDE

LINE

using your

ruler and a

pencil.


The basics of ploting ocean locations the gps latitude longitude

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W

34O 00.50’N

(green line)

is just a tiny

bit North of

34O 00.00’N


The basics of ploting ocean locations the gps latitude longitude

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W

34O 00.50’N

[our location is

someplace along

this green line]


The basics of ploting ocean locations the gps latitude longitude

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W

Next, let’s

draw the

LONGITUDE

LINE

using your

ruler and a

pencil.


The basics of ploting ocean locations the gps latitude longitude

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W

118O 29.10’W

(yellow line)

is just a tiny

bit before

118O 30.00’W


The basics of ploting ocean locations the gps latitude longitude

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W

The Santa

Monica Pier

is located where

the two lines

cross each other.
