Nationl Grid Reference System
To give a grid reference correct to about 100 meters, locate the spot on
the map for which you want to give the coordinates. Let's use
Springfield in Thornhill as our example. Scroll to the left edge of
this map and determine if Springfield is in the upper part of this map
labeled NN7... or the lower part of this map labeled NS6.... Notice
that Springfield is in the part labeled NN so write down NN for
Springfield. Next, return to Springfield & scroll up to determine
how far east it is. Ignore the leading 2. Springfield is east
of the line NN66. Estimate how many tenths Springfield is east of the
NN66 grid line. It seems to be about 4/10 of the way from NN66 toward
NN67 so append 4 to NN66. Now we have Springfield is at Easting of
664. Now look west of Springfield to see how far north it is
estimating how many tenths it is above the line. It is 7001.
Drop the 7 & append it to the Easting and we have 664001. Add the
easting & northing to the grid letters NN & we have NN664001 is the
location to the nearest 100 meters, since the grid lines are 1,000 meters
(1 kilometer) apart . This is the accepted method of telling someone
where something is on modern British maps.
