The map layers showing Irish boundaries is now updated every 15 minutes. This includes county/barony/civil parish/ed and townlands.
The map server starts updates at 05/20/35/50 minutes past the hour and should have all Irish edits up to 00/15/30/45 minutes past respectively. Updates should take about 2 minutes. I also updated the townland layer to show area in fractional acres from zoom 14 onwards. This may help you compare the acreage value shown on the GSGS3906 maps to help spot obvious errors. For example, I picked a spot at random below and you can see that there are a few areas that have the wrong acreage due to some townlands being missed: http://maps.openstreetmap.ie/oocmaps.html?zoom=15&lat=53.71215&lon=-6.91047&layers=000B0TFFFFTFFF eg Barfordstown is reported as 482 acres as we actually included two townlands Barfordstown 283 acres and Boolies 198 acres. There's a similar issue with Calliaghstown nearby. When comparing fractional acres and ARP (acres,roods, perches) on the map, bear in mind that: 1 acre = 4 roods 1 rood = 40 perches You'll also notice a small difference in the acreage size reported by townlands.ie and the map layer. That is due to the map layer transforming to Irish Grid when calculating the area to get a slightly more accurate calculation. Townlands.ie has to do a lot more analysis so uses a different spatial reference system. Anyway hope it helps.
