Grid Reference

Question 1

Grid lines

Answer 1

Eastings – vertical lines that run from west to east

Northings – horizontal lines that run from south to north

Grid lines are numbered to provide the coordinates of specific
features on a map

Question 2

Grid Reference

Answer 2

Set of digits formed using the grid values of eastings and
northings

Defines a location on a map

The more digits in a grid reference, the more precise the
location, e.g. a six-figure grid reference gives a more accurate
location than a four-figure grid reference

Question 3

Four-figure grid reference

Answer 3

Identifies a specific grid square

First two digits = Value of the easting on the left of the
square

Second two digits = Value of the northing at the bottom
of the square
