On Doagh Isle there is a lot of rock art recorded. A lot of the panels have become overgrown, or were destroyed in the late 1980s, but there are still many to be found. Due to very bad weather I only managed a few of them. The panels here have a unique design - a round-cornered rectangle with parallel lines carved across it, known as a cartouche.
This location has two visible panels. The western one has a series of close parellel lines. The other is similar, but incredibly unusual. It is a rounded recatnagle filled with parallel lines, but in the centre there is a cup and ring motif. This design is much bigger than the cartouches found on other panels.
It is possible to still see the pecking marks in the grooves on both panels, so I don't think they've been exposed for very long. The lesser panels seems to be on a route taken by a tractor, so it could be best that it becomes overgrown again to protect it.
This is an explanation of (and a bit of a disclaimer for) the coordinates I provide.
Where a GPS figure is given this is the master for all other coordinates. According to my Garmin these are quite accurate.
Where there is no GPS figure the 6 figure grid reference is master for the others. This may not be very accurate as it could have come from the OS maps and could have been read by eye. Consequently, all other cordinates are going to have inaccuracies.
The calculation of Longitude and Latitude uses an algorithm that is not 100% accurate. The long/lat figures are used as a basis for calculating the UTM & ITM coordinates. Consequently, UTM & ITM coordinates are slightly out.
UTM is a global coordinate system - Universal Transverse Mercator - that is at the core of the GPS system.
ITM is the new coordinate system - Irish Transverse Mercator - that is more accurate and more GPS friendly than the Irish Grid Reference system. This will be used on the next generation of Irish OS maps.
