We in the OpenStreetMap Ireland community are trying to add some of Ireland’s smallest administrative units, townlands, aswell as other historically relevant boundaries like baronies and civil parishes.

I’ve made a site showing Irish Traditional Townland’s which shows the details of each townland and barony and civil parish in the country. We still have a lot to do. We focussed on the townlands, baronies and civil parishes of Co. Carlow first.

I also added a townland mapping progress, which shows how much we have mapped of each area. I also added some county by county data completeness checks, showing gaps and overlaps.
