LATITUDE

Lines go east

and west.

LONGITUDE

Lines go north

and south.

Map: http://worldatlas.com/aatlas/imageg.htm

a GLOBAL POSITIONING

SATELLITE RECEIVER is

used to measure and record

the LATITUDE and

LONGITUDE of a

LOCATION in DEGREES,

and MINUTES.

27 Global Positioning Satellites (effective 9/28/98)

At least 4 GPSatellites must be locked in to give

Latitude, Longitude, Elevation and GPS Time.

Materials needed for this sample activity:

Copies of Santa Monica Bay

or southern California chart

pencils

Ruler or

straight-edge

Location data

(from GPS)

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.

area

NOTICE THAT THE GRIDLINES ON THIS CHART ARE

EQUAL TO 5’ (minutes) EACH.

LOCATE THE SANTA MONICA PIER

GIVEN: THE SANTA MONICA PIER IS LOCATED AT

34O 00.50’N and 118O 29.10’W

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.

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

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]

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.

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

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.

GIVEN: THE MANHATTAN BCH. PIER IS LOCATED AT

33O 53.00’N and 118O 24.90’W

X

33O 53.00’ is

between 33O 50’

and 33O 55’

TO PLOT A LOCATION ON A CHART

1. FIND THE LATITUDE LINE

2. FIND THE LONGITUDE LINE

3. PLACE AN “x” WHERE THE TWO

LINES CROSS

the spot !
