I've been working on tracing townlands by Lough Conn, Mayo and don't know how to deal with some boundaries due to the drop in lake levels from drainage works. Here http://osm.org/go/etJ86lqw-?m= you can see that I've left out four townlands: Scotchfort, Cappanaglogh, Cloonygunnaun, and 'Cappanaglogh (Part Of): you can see that the latter is between Cappanaglogh, Cloonygunnaun, and with the lake level change and the inclusion of a previous island into the townland it's not clear how a new boundary should be drawn.
A related issue is whether the boundaries should be redrawn at all here, or if the original pre-drainage works lake level boundary should be respected (I looked at Lough Gara and see that the tracing has followed the new lake level). The GIS townland layer I have used before has kept the original townland size and not changed the outline to match the 'new' lake level. I'd appreciate advice on this, Killian Driscoll Banting Postdoctoral Fellow Département d'anthropologie Université de Montréal umontreal.academia.edu/KillianDriscoll www.lithicsireland.ie ca.linkedin.com/in/killiandriscoll _______________________________________________ Talk-ie mailing list Talk-ie@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-ie
