I guess the situation is different as the waterway changes in Ireland have not caused disputes. The townland boundaries that are set by the commision have not changed, but in osm we are changing them, and amending the boundaries to suit the map rather than the official boundary, Killian Driscoll

Thanks - Inishfale isn't a townland on the GIS layer I have (maybe an error with that layer?). I wasn't doubting Beggerin was a townland! Just looking for it: I found it on my GIS layer. I can't see the orig OS maps here http://maps.openstreetmap.ie/oocmaps.html for the Beggerin Island area. Are

You can check the online 1901 townland index (there is also a 1911 supplement at same site) and see Beggerin Island is listed:

Hi Killian, I'm trying to recall what was done in the past for this as I'm sure it's come up. To the best of my recollection, stick with the boundary markings as they exist on the map sheets. Dave On 14 May 2015 22:12, Killian Driscoll killiandrisc...@gmail.com wrote: I've been working on

Some of the townlands did have their boundary updated, such as Rock Big in Wicklow (http://www.openstreetmap.org/#map=15/52.7749/-6.1459) , see http://www.irishstatutebook.ie/1994/en/si/0333.html . But that seems to be more of an exception than a rule. Personally I would put the boundary on

I guess it comes down to what we are doing here. By changing the boundary to match the new shoreline we are in effect changing the townland size, and also creating anomalies whereby e.g. Irish monuments are now appearing in townlands where there are not there officially according to the sites and

Thanks. stick with the boundary markings as they exist on the map sheets: if you scan the lake edges of e.g. Lough Neagh, Gara, Derravaragh, Allen etc. that have lowered lake levels the traced townland boundaries all now match the new lake level, so I think the map sheets have been ignored and new

I read that thread, I figured there was something about it before, just couldn't recall. If I'm honest, I think my opinion has changed from the one I originally stated in that thread on the basis that townland boundaries are changed through statutory instruments only (as far as I am aware). I'd

I guess the point is 'Inishfale Island' was never an official townland (at least the name doesn't turn up on the online databases, I don't have access to the print copy): the sites and monuments record uses 'Inisfale Island' as the name. Is/was Beggerin Island a townland? Killian Driscoll Banting
