So here are the answers to yesterday’s ‘Are you an outdoor woman?’ quiz, ‘What’s on a map?’
- How did Britain’s mapping agency Ordnance Survey start?
b) The Scottish were rebelling and it was decided that military maps of the Scottish highlands were needed. (Talk about tackling the hardest job first!)
2. What does the colour blue usually denote on an Ordnance Survey map?
c) Water, grid lines and points of interest? (We Blondes think it is a particularly nice shade of blue but would like to point out that British water is rarely any kind of blue let alone the blue with the hex code 00AEEF!)
3. How much height gain (or loss) would you expect when walking between two orange contour lines on a 1:25,000 scale map?
a) It depends which 1:25,000 map you are looking at. (Odd answer this but it is true, either 5 metres in lowland areas or 10 metres in upland areas, a double decker bus is around 5 metres if this helps you to visualise it.)
4. Would it be easier to navigate in a forest full of little pointy trees (on the map) or little roundy trees (on the map)?
a) You can navigate through either but you will need to use your compass carefully. (Forests can sometimes flummox the most skilled of navigators because tracks often do not match those on the map and it is sometimes impossible to walk on a direct bearing.)
5. What does a strange bump in the middle of a contour line mean?
b) A re-entrant or a spur. (Contour lines have to join up points of the same height above sea-level so if a contour line shows a kink it will be a re-entrant (dip) or spur (mound) in the ground.)
6. What is the difference in area between a blue grid square on a metric 1:25,000 map and one on a metric 1:50,000 map?
b) Nothing they both represent the same area. (Nice and easy this one – 1 blue square = 1 kilometre = 15 minutes walking.)
7. What do Dick’s Well, Brown Willy and Cock’s Hill all have in common?
c) They all made you giggle when you read them. (Really we are shocked at you all!)
8. If you were standing at the top of a hill and looking down at numbered contour lines, which way up would the numbers be?
a) Upside down. (It is usually easy to spot a hill as the contour lines show ever-smaller concentric circles but along a ridge you may need to know this.)
9. What does the map symbol that looks like a giant blue duck represent?
a) A nature reserve. (We have heard that a few very special nature reserves in the UK do actually have giant blue ducks!)
10. Name 2 Ordnance Survey UK maps that are double-sided and 2 that are single sided.
This one is up to you… we will trust your womanly integrity! Our answers would be: Double-sided – The Brecon Beacons and Dartmoor. Single-sided – The Isles of Scilly and The Malvern Hills.
You can give yourself 1 mark for each correct answer on this section of our, ‘Are you an outdoor woman?’ quiz. If, after this, you feel like you could do with a few more map skills, get yourself booked on one of our three navigation workshops this summer.
