Maps: The Language of Where
A map is a picture of the world from above. It compresses kilometres of landscape into a sheet you can hold in your hands. For thousands of years, maps have been humanity's way of understanding where we are and how to get where we're going.
In the age of GPS, map-reading feels old-fashioned. But phones die, signals fail, and satellites go offline. Knowing how to read a map is a skill that never needs charging.
The Basics of Map Reading
Orientation
By convention, north is at the top of almost every modern map. When using a physical map outdoors, rotate it so north on the map aligns with north in reality. Now the map matches the landscape around you.
The Legend (Key)
Every map has a legend explaining its symbols. Common symbols on topographic maps:
- Blue: Water (rivers, lakes, ocean)
- Green: Vegetation (forests, parks)
- Brown: Contour lines (elevation)
- Black: Human-made features (roads, buildings, boundaries)
- Red: Major roads
Always read the legend first. Different maps use different symbols.
Scale
Scale tells you the relationship between distance on the map and distance in reality. Common scales:
- 1:25,000 — 1cm on the map = 250 metres in reality (detailed, good for walking)
- 1:50,000 — 1cm = 500 metres (good for cycling, general hiking)
- 1:100,000 — 1cm = 1 kilometre (good for driving)
To measure distance on a map: use a ruler or piece of string along the route, then multiply by the scale.
Types of Maps
- Topographic maps: Show terrain, elevation, and natural features. Essential for bushwalking.
- Street maps: Show roads, streets, and addresses. What most people are familiar with.
- Nautical charts: For water navigation. Show depth, currents, and hazards.
- Thematic maps: Show specific data — weather, population, election results, etc.
Tonight's Question
"Without looking at a phone, can anyone draw a rough map of our neighbourhood from memory? Include our house, the nearest school, shop, and park."
This tests your mental map — your internal understanding of your surroundings.
Map Exploration
- Get a physical topographic map of your local area (available from map shops, some newsagents, or print from mapshare.vic.gov.au / maps.six.nsw.gov.au).
- Find your house on the map.
- Identify five features you recognise: your school, a park, a river, a hill, a main road.
- Measure the distance from your house to school using the scale.
- Discuss: what can you see on the map that you didn't know was near you?

- History: How did Aboriginal Australians navigate without paper maps? (Hint: songlines, oral maps encoded in story and song.)
- Book: Map Reading Skills by the Scouting Association — practical guide for young people.
- Challenge: Navigate from your house to a nearby landmark using only a paper map (no phone).
What We Simplified
- North isn't always at the top. Historical maps and some modern ones place other directions at the top. "North up" is a convention, not a rule.
- Maps are always distortions. Projecting a spherical Earth onto flat paper inevitably distorts something — area, shape, distance, or direction. The Mercator projection makes Greenland look as large as Africa (it's 14 times smaller).
- Digital maps are still maps. Google Maps uses the same principles — scale, symbols, orientation — just with added features like real-time traffic.
