ANSWERS BELOW ↓
ANSWERS
1. c. 250 M. If a map has a scale of 1:25000, this means that 1 cm on the map is equivalent 25000 cm in real life, which is 250 m or 0.25 km. So, if 1 cm is 0.25 km, then 4 cm will represent 1 km in real life.
2. d.1:250,000.The terms 'large scale' and 'small scale' are used to describe different scales. However, they can be confusing: large scale maps have low number in the scale, such as 1: 1250. The features shown are large. Small scale maps have a high number in the scale, such as 1: 250 000. Individual features shown are small.
3. b.1:25,000.The 1:25 000 scale map is very useful for walking as it shows many features including paths and buildings over a small area, but if you use it in a car you will quickly drive off the edge! On the other hand, maps at 1:250,000 scale (note the extra zero) show lots more area, but in far less detail.
4. c. Triangulation Pillars. The triangulation pillar, most often known as a "trig pillar" or "trig point" is a fixed surveying station, used in geodetic surveying and mapping.
5. d.6000 plus. Although more than 6,500 trig pillars were built, hundreds have been lost to housing developments, farming, coastal erosion, and other causes. Trig-baggers collect round 6,190 points currently.
6. b. Blue triangle symbol The symbol for a trig point is a small blue triangle, sometimes with a blue dot in the centre. The number beside it shows the height above sea level.
7. c. Contour Lines. Contour lines mark points of equal elevation on a map. If you trace the length of a line with your finger, each point you touch is the same height above sea level. When shown close together, the land is steeper.
8. a. Vertical lines down a map. A grid of squares helps a map-reader locate a place. The vertical lines are called eastings. They are numbered - the numbers increase to the east. The horizontal lines are called northings as the numbers increase in a northerly direction.
9. b. Eastings. To avoid confusion, convention is that you should always give the eastings number first and the northings second. you must also give the 2 letter prefix that denotes which 100km x 100km grid square you are in.
10. c.NNW. On a compass, NNW (North North West) lies immediately opposite SSE (South South East).
11. d. South Pole. This question used to be asked by old Antarctic expedition leaders of applicants to join expeditions.
12. a. Exmoor. The stag with its proud antlers, in an upturned blue triangle is the symbol for Exmoor National Park
13. b. Footpath. The green dotted lines are footpaths with a public right of way. They are legally protected routes that the public may use by foot.
14. d. Blue. For familiarity and confidence, all tourist features are depicted on OS maps in light blue.
15. a. OL17 Snowdon. Although Snowdon is number one, these are four of the most popular maps, revealing where Britons are most likely to go on holiday or perhaps where they are most worried about getting lost.
16. c. Glen Cassley & Glen Oykel. Map 440, covering Glen Cassley & Glen Oykel, a beautifully barren wilderness in the northern Highlands, is the number 1 hidden treasure, recording the lowest sales of any OS Explorer map.
