Q

What is scale?

A

Scale is a proportion between a legnth on a map and the legnth that it represents on the ground.

18
Q

The bigger the area covered by the map, the …….. the map scale.

A

Smaller

19
Q

The smaller the area covered by the map, the …….. the map scale.

A

Bigger

20
Q

Name the four types of scales and an example how the scale could be represented in this form.

A
  • Numerical ratio scale (1 : 8 000 000)
  • Representative fraction (1/8 000 000)
  • Linear scale (0__80__160__240__320__400)
  • Word scale (One unit on the map represents eight million units in reality)

A

22
Q

What angle does each compass point (N-NNE etc) go up by?

A

22.5 degrees

23
Q

What is bearing?

A

The angular distance measured from true north in a clockwise direction.

24
Q

Where do you first place your compass when measuring bearing?

A

On the north line of the point you’re measuring from, and measuring in a clockwise direction from this north line, running towards your second point.

25
Q

How many minutes are there in a degree?

A

60’

26
Q

When writing a co-ordinate which lines are given first?

A

First LATITUDE (S and N) and longitude minutes.

Then longitute (W and E) and longitude minutes.

Eg. 33* 55’ S 18* 26’ E
(pretend * is degree)

27
Q

How do you work out a co-ordinate’s minutes?

A
  • Measure the amount of cm in 60’ (1 degree) on the map.
  • Divide the amount of cm of the co-ordinate’s minutes by the total amount of cm in a degree (as worked out above).
  • Take your answer after dividing and multiply by 60.

This will give you the minutes of whichever line you’re working out (latitude/longitude) .

Eg.
(0.8cm ÷ 3.4cm) x 60 = 14 (round off)
Therefor …* 14’S

28
Q

When working out distance, how do you use the scale to convert the distance on the map, to realistic kilometres?

A
  • Measure the amount of cm it is from the co-ordinate’s you’re measuring the distance between.
  • Take the amount of centimetres between the two co-ordinate’s you just measured and multiply it by the scale (eg, if you get 5.1cm, and the scale is 1 : 8 000 000; you’d go 5.1 x 8 000 000)

-Take the answer you get (in this case 5.1 x 8 000 000 which is 40 800 000) and divide it by 100 000 to convert into km.
=408km
