Geographical skills: maps, data and fieldwork

What you'll learn

1. 1

   Primary data you collect yourself. Secondary data someone else collected.

2. 2

   A six-figure grid reference locates a point to about 100 m. Read the easting first (across the bottom), then the northing (up the side).

3. 3

   Which do you read first in a grid reference?

4. 4

   A traffic count you carry out yourself is which kind of data?

5. 5

   Apply it: a 4-figure grid reference names a whole square; 6-figure pinpoints within it. Always read along the bottom first, then up — "along the corridor, up the stairs".

6. 6

   Contour lines very close together show what?

7. 7

   In a grid reference, which do you read first?
