N_v_ g _ _ n Ø Shhh, don’t use that word! Ø I can’t do it. Ø I don’t know how to. Ø Other people do that. Ø It’s too hard, I can’t learn how. Ø Only the hard walkers need that – not me! BWV Walk Leader Training Unit 6 – Navigation 2

Who recognises that picture? Excellent! Everyone does! 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 8

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. BWV Walk Leader Training Unit 6 – Navigation 10

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: BWV Walk Leader Training Unit 6 – Navigation 11

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. BWV Walk Leader Training Unit 6 – Navigation 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. BWV Walk Leader Training Unit 6 – Navigation 16

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. BWV Walk Leader Training Unit 6 – Navigation 18

This slide shows part of the Warby Range map. BWV Walk Leader Training Unit 6 – Navigation 19

Let’s find some interesting things on this map. Work with the person next to you to find and discuss some of these things: Ø Roads; Ø Tracks; Ø Waterways; Ø Contours; Ø Can you locate a hill? Are you sure it’s a hill? BWV Walk Leader Training Unit 6 – Navigation 20

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

ØA mere 50 km south-east of Horsham, what is the most striking piece of topography just a bit off the highway? ØWho answered Grampians (Gariwerd)? ØHas anyone here been camping or walking in that area? BWV Walk Leader Training Unit 6 – Navigation 22

ØSo, topography is the shape of the land, and a topographic map shows you the shape of the land. ØHow do you “see” the 3 D shape of the land from a flat piece of paper? ØWho answered “contour lines”? BWV Walk Leader Training Unit 6 – Navigation 23

To recap Ø You can all read maps! Ø You may not all be able to read all maps. Ø But you can learn! Ø To transform a flat piece of paper into a representation of the land it shows, you have to show the land goes up and down. Ø When you do this with contours, you are using or looking at a topographic map. BWV Walk Leader Training Unit 6 – Navigation 24

Technical information taken from Geoscience Australia www. ga. gov. au Ø Topographic maps are detailed, accurate graphic representations of features that appear on the Earth's surface. These features include: Ø cultural: roads, buildings, urban development, railways, airports, names of places and geographic features, administrative boundaries, state and international borders, reserves Ø hydrography: lakes, rivers, streams, swamps, coastal flats Ø relief: mountains, valleys, slopes, depressions Ø vegetation: wooded and cleared areas, vineyards and orchards. Ø A map legend (or key) lists the features shown on that map, and their corresponding symbols. BWV Walk Leader Training Unit 6 – Navigation 25

There are topographic features which have common or a reasonably obvious appearance when shown as contour lines. BWV Walk Leader Training Unit 6 – Navigation 26

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