Map projections

A map projection is a method of representing the earth’s curved (3D) surface on a flat (2D) map.

A map projection is a compromise between size/area and shape

Scale

• Each map has a "scale" which indicates the relationship between a certain distance on the map and the real distance on the ground

• 4 ways of showing scale – and they are?

• Remember…– …smaller scale = large area but less detail (e.g. 1:8,000,000)

– …larger scale = small area but more detail (e.g. 1:25,000)

Using Scale on maps

Look at pages 2 & 3 in your atlas and answer the following questions:

1. Write a definition explaining the meaning of scales

2. Identify 4 ways that scale can be used and give an example of each

3. State the scale as a ratio of figures 2-6 on pages 2 & 3

4. Is the map in figure 3 a larger or smaller scale than figure 4?

Calculating Bearings

Using your protractor and page 148-149 of the atlas answer the following:

1. Give the direction from London of:a) Parisb) Berlinc) Lisbond) Rekyavik

2. Give the bearing from Prague of:a) Warsawb) Romec) Ankarad) Madride) Dublin

Bearings – Be careful

• Bearings on maps DO NOT represent the bearing you take with a magnetic compass.

• Why not…?
