I would like to acknowledge the indispensable assistance which I have
received from the Ordnance Survey maps. I hope the Ordnance Survey Office of
Ireland don't mind me reproducing this map of the national grid below. I love
maps and over the years I have bought practically every road map the OS have
produced, including all 89 of the 1:50,000 Discovery Series which I
cherish and protect. As well as that I have spent a small fortune on the
six-inch-to-a-mile sheets corresponding to a wide sweep of my home area.
I would strongly encourage every
Irish visitor to this site to purchase a copy of the Discovery Series map of
your area. It shows detail down to every farm entrance. Each of these maps
costs about 6.60 and are available at most newsagents.
Ordnance Survey Grid
The Grid Reference numbers I am using in
these pages follow the OS grid of Ireland as shown on the left.
The country is divided into 25 squares
with letters to name them. So Cork is in square W
as you can see. However, in order to give a more accurate reference for an area
we always use the 'six-figure reference'. To do this you first note the letter
of the square in which the target area is to be found, eg.
W. A good map will divide each of these squares
into 10 or 100 smaller squares. This is how you get the six-figure number. The
first three figures are the displacement along the line under the area in
percentages to one decimal point. The second three figures are the displacement
along the line to the left of the area. So the centre of the red spot denoting
Cork would be shown in a good scale map to be 71.5 across and 69.0 up.
Therefore: W 715 690 is the six-figure reference
This is the way one locates a place from
practically every kind of a map in the world. If your forget whether you are
supposed to go across first or up first try to remember the
"you must crawl before you can
|| In my references I preserve the
integrity of the six-figure reference (S 239 184). This kind of reference
points to a particular piece of the country with an area of 100 Square Metres.
