What is a Topographic Map?

In contrast to most maps, a topographic map shows the shape of the Earth’s surface

by using contour lines.

Page 3: Topographic  moodle

Contours are imaginary lines that join points of equal elevation above or

below sea level.

Page 4: Topographic  moodle

Let’s take a walk up a hill!

Page 5: Topographic  moodle

We’re now at an elevation of 100 meters.

100m

Page 6: Topographic  moodle

Let’s keep going!

100m

Page 7: Topographic  moodle

Now we’re at 200m.

100m

200m

Page 8: Topographic  moodle

Shall we march on?

100m

200m

Page 9: Topographic  moodle

We’ve made it to 300m!

200m

300m

Page 10: Topographic  moodle

On to the peak!

100m

200m

300m

Page 11: Topographic  moodle

We’re on the peak, but what’s our elevation?

100m

200m

300m

Page 12: Topographic  moodle

Any ideas?

100m

200m

300m

Let’sadd contour lines for every 50 meters and see if that helps.

We know that we are above 350m, but less than 400m.

Let’s head down the hill, it’s getting late!

200m

300m

Now what’s our elevation?

50m

150m

250m

350m

If you said somewhere between 200m and 250m you are right!

Let’s try this again!

300m

What’s our elevation now?

50m

150m

250m

350m

If you said 50m or just under, you’re right!

Page 18: Topographic  moodle

Let’s now look at the same hill, but the way we

might see it from an airplane!

Page 19: Topographic  moodle

Each color change represents a 50 meter increase.

Page 20: Topographic  moodle

Now, let’s try the same hike! Our elevation is 0 meters.

Page 21: Topographic  moodle

Now what is our elevation?

Page 22: Topographic  moodle

If you said more than 150 meters, but less than 200

meters your right!

Page 23: Topographic  moodle

Let’s go a little higher.

Page 24: Topographic  moodle

Think you know our elevation now?

More than 300meters

But less than 350meters

Page 25: Topographic  moodle

If we were standing on the peak, what would be our

elevation?•More than 350 meters,

less than 400 meters

Page 26: Topographic  moodle

Let’s head down hill.

Page 27: Topographic  moodle

Know our elevation?

Page 28: Topographic  moodle

More than 100 meters,

less than 150 meters

Grab a piece of paper and write your answers to the following questions.

Ready?
