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.
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 are shown are large. Small scale maps have a high number in the scale, such as 1: 250 000. Individual features shown are small
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.
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.
D) 6,000 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 around 6,190 points currently.
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.
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.
C) 3
A diagram at the bottom of most topographic maps shows three north arrows and the angles between them: grid north (GN) is a navigational term referring to the direction northwards along the grid lines of a map projection. It is contrasted with true north (the direction of the North Pole) and magnetic north (the direction in which a compass needle points).
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.
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.
D) South Pole
This question used to be asked by old Antarctic expedition leaders of applicants to join expeditions.
B) Footpath
The short green dashes are footpaths with a public right of way. They are legally protected routes that the public may use by foot - a bridleway is shown as long green dashes.
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.
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.
D) All of you
Everyone should be paying attention to the navigation, either to advise or to learn. Being aware of where you are and where you are going also adds to your confidence and enjoyment too.
Score Yourself
So, how did you do? There are no prizes so, just for fun, score yourself...
1-3: Ah, that's not great! Brush up on your knowledge, join our navigation skills courses and have another go!
4 - 7: Could do better...hmmm, you've got lot's to learn about maps and navigating the british countryside. Guess you should start planning a trip...
8 - 11: Not bad but there's room for improvement and there are lots more places to discover so keep on exploring!
12 - 15: That's great, well done! You know lots about maps and navigation, time now to get to grips with the last few.
16 - 18: Excellent, what a result! Great knowledge, you clearly know your stuff and are a map reading pro.
