Shhh, don’t use that word!
I can’t do it.
I don’t know how to.
Other people do that.
It’s too hard, I can’t learn how.
Only the hard walkers need that – not me!

So, all of you know what a map is,
don’t you?
And you know how to use them.
BWV Walk Leader Training Unit 6 – Navigation

Here is a map for you.
Who reckons they don’t know how
to use this map?
Well, since you do already know
about maps, as we’ve seen, learning
a bit more and using a map like
this is something everyone of you
here CAN do.

Brainstorming activity
What is on this map that you may not
have seen before, may not understand
or may think that will be too hard to
learn?
Let’s start a list:

So, how will this map be useful to us as
bushwalkers?
How will these things listed on the whiteboard
give us more information than using a Parks
Vic map or the Melways?
The biggest difference with a topographic map
is that it shows us topography – topography is
what the land looks like. Let’s look at such a
map in more detail now.

12
Question – does Melways have a legend?
BWV Walk Leader Training Unit 6 – Navigation
13
Do Parks Vic maps have a legend?
BWV Walk Leader Training Unit 6 – Navigation
14
So you’re already familiar with
legends!
BWV Walk Leader Training Unit 6 – Navigation
15
Topo maps just have
a bit more information
in them than other
legends.

Now it’s your turn!
Have a good look at the map in front of you.
It’s called Warby Range.
Now see if you can find this particular part
of the map.

This slide shows part of the Warby Range map.

Let’s find some interesting things on this map.
Work with the person next to you to find and
discuss some of these things:
 Roads;
 Tracks;
 Waterways;
 Contours;
 Can you locate a hill? Are you sure it’s a hill?

Topography
This is called a topographic map
because it shows topography.
Who’s driven the Western Highway to
South Australia?
What’s the topography like between
Horsham and Kaniva?
BWV Walk Leader Training Unit 6 – Navigation
21
A mere 50km south-east of Horsham,
what is the most striking piece of
topography just a bit off the highway?
Who answered Grampians (Gariwerd)?
Has anyone here been camping or
walking in that area?
BWV Walk Leader Training Unit 6 – Navigation
22
So, topography is the shape of the
land, and a topographic map shows
you the shape of the land.
How do you “see” the 3D shape of
the land from a flat piece of paper?
Who answered “contour lines”?

To recap
 You can all read maps!
 You may not all be able to read all maps.
 But you can learn!
 To transform a flat piece of paper into a
representation of the land it shows, you have to
show how the land goes up and down.
 When you do this with contours, you are using
or looking at a topographic map.

 Topographic maps are detailed, accurate graphic
representations of features that appear on the Earth's
surface. These features include:
 cultural: roads, buildings, urban development, railways,
airports, names of places and geographic features,
administrative boundaries, state and international
borders, reserves
 hydrography: lakes, rivers, streams, swamps, coastal
flats
 relief: mountains, valleys, slopes, depressions
 vegetation: wooded and cleared areas, vineyards and
orchards.
 A map legend (or key) lists the features shown on that
map, and their corresponding symbols.

There are topographic features
which have common or a
reasonably obvious appearance
when shown as contour lines.

One way to think about ridges, spurs and
gullies is to look at your hand!

Recap
 We all do know about maps.
 We mostly know how to use maps.
 We now know a bit about topographic maps.
 We want to learn more about understanding
and reading contours, so we can plan our
walks much more accurately.
 Understanding how to read contours shows
us in our mind what the country looks like.
