Mapwork Flashcards
How would you identify a PHYSICAL MAP?
Uses different colors (or symbols) to show the relief (build) of the land.
How would you identify a POLITICAL MAP?
Shows the boundaries of countries, provinces or other political divisions. They also show towns and settlement features.
How would you identify a THEMATIC MAP?
Contain data that is linked to a specific theme, eg to show resources, population density, climate, quality of life.
How would you identify a ORTHOPHOTO MAP?
Looks like an aerial photo but is not distorted by camera tilt. (Often have contour lines and road names printed onto them.
How would you identify a TOPOGRAPHIC MAP?
A map which accurately depicts the PHYSICAL features and relief of an area. (Using contour lines, beacons and landmarks. Eg, post office, schools.)

What is scale?
Scale is a proportion between a legnth on a map and the legnth that it represents on the ground.
The bigger the area covered by the map, the …….. the map scale.
Smaller
The smaller the area covered by the map, the …….. the map scale.
Bigger
Name the four types of scales and an example how the scale could be represented in this form.
- 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)

What angle does each compass point (N-NNE etc) go up by?
22.5 degrees
What is bearing?
The angular distance measured from true north in a clockwise direction.
Where do you first place your compass when measuring bearing?
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.
How many minutes are there in a degree?
60’
When writing a co-ordinate which lines are given first?
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)
How do you work out a co-ordinate’s minutes?
- 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
When working out distance, how do you use the scale to convert the distance on the map, to realistic kilometres?
- 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
