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.
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 activityWhat 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:
12BWV Walk Leader Training Unit 6 – Navigation
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.
13BWV Walk Leader Training Unit 6 – Navigation
Question – does Melways have a legend?
14BWV Walk Leader Training Unit 6 – Navigation
Do Parks Vic maps have a legend?
15BWV Walk Leader Training Unit 6 – Navigation
So you’re already familiar with legends!
16BWV Walk Leader Training Unit 6 – Navigation
Topo maps just havea bit more information in them than other legends.

18BWV Walk Leader Training Unit 6 – Navigation
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?

TopographyThis 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?
22BWV Walk Leader Training Unit 6 – Navigation
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?
23BWV Walk Leader Training Unit 6 – Navigation
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”?
24BWV Walk Leader Training Unit 6 – Navigation
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.
Technical informationtaken from Geoscience Australia www.ga.gov.au

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!

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.
