Grid References
OS Maps have a grid covering the map, which allow you to work out where different places are.
Grid lines
- The map is covered in a grid and each line is labelled with numbers.
- The horizontal lines from west to east are called eastings.
- The vertical lines from south to north are called northings.
- Each line has numbers along the side so that we can create grid references.
Four-figure grid reference
- We use four-figure grid references to identify a feature within a single square.
- To find a four-figure grid reference we follow the grid lines down from the bottom left corner to the axis.
Six-figure grid references
- We use six-figure grid references to be more specific within a square.
- To find the six-figure grid reference, you have to imagine the square is divided into 100 mini squares.
