Grid References

 

 

Most maps include a grid marked with numbers down the side know as northings and along the bottom known as eastings.  To make a grid reference, follow the vertical line just left of the chosen location down to the foot of the map to read its easting – for example, 04.

 

Estimate the number of tenths from the grid line to the location (410).  the line “first walk into the house, then climb the stairs,” will remind you always to state the easting first.
