There used to be a map showing Ireland townlands like this. Can we see a map of townlands anywhere?
Both of these are unreachable though
http://dev3.openstreetmap.ie/osm/slippymap.html is unreachable.
https://maps.openstreetmap.ie/ is unreachable.
I have downloaded an area in JOSM but can’t see where townland information is. I can see a list of boundaries in the bottom right area but not sure if any of those are townlands. Can we see a map of townlands in JOSM?
Oh townlands! I know this. There is still the website https://townlands.ie/ which I made years ago. It no longer updates. The source code is GitHub - osmie/osm-irish-townlands: Django web application to analyze irish traditional boundries from OSM · GitHub
Note that many locations in Ireland are also cross-reference to Logainm.ie, e.g. Way: Otter Island (1083328923) | OpenStreetMap and Oileán an Mhada Uisce/Otter Island | logainm.ie
It’s not exactly what you’re looking for, but this map shows townland names and boundaries (in addition to lots of other detail that you’re likely not interested in). Townland names are shown from raster zoom 11 or so (but often get obscured by other things); boundaries (when the boundaries layer is enabled) from raster zoom 13:
The database behind that has all sorts of other boundaries in it and gets used for QA when these break (as happens frequently).
Ok thanks Andy, Victor and Amanda.
Yes logainm actually has a map of all townlands Victor. I saw the logainm map and individual townland maps on townlands.ie after I posted.
The townland boundaries on townlands.ie and atownsend.org.uk are the same, probably OSM data. The logainm boundaries are slightly different. Example:
Whitehall looks pretty similar to me - at least at the level of detail available (on both sides)?
Here’s a quick Postpass query to get you all the townlands in Ireland: view the map here
select *
from postpass_polygon
where
geom && ST_MakeEnvelope(-12, 51, -5, 56, 4326)
and ST_Contains(ST_SetSRID('POLYGON((-12 56,-12 51,-6 51, -5 54,-5.5 55,-7 55.9, -12 56))'::geometry, 4326), geom)
AND tags @> '{"admin_level":"10"}'::jsonb
Back at my computer. There’s a significant difference on the west Andy. Can you see in these screenshots?
That is a great map Amanda. Thank you
Yes, but the townlands.ie one says “Last update: April 24, 2022, 8:30 a.m”. 3 edits in 2023 resolved the differences.
Oh right. Very good, thanks Andy
yes, mea culpa. Townlands.ie used to update every day. But the townlands are all mostly mapped by now. The Django web app to make the site osm-irish-townlands doesn’t work on recent versions of ubuntu/debian. So I just changed it to a flat mirror that doesn’t change. Sorry.
No worries, makes sense. Thanks Amanda
True, but 2 or 3 get broken every couple of days and 2 or 3 get fixed (often by the same people!).
If anyone wants to het an early morning email of “yesterday’s broken townlands” (and baronies, and dioceses, etc.) let me know…
The Irish government have an open data map of townlands here.
Nice, thanks @Thosewhoknow. Anybody know was the data on that government site compared to the OSM data? @SomeoneElse, @amapanda_ᚐᚋᚐᚅᚇᚐ ? Maybe the data there is ESRI data, not sure. If it’s government data, I’d hope it’s pretty correct so a good source to compare to OSM data to check OSM has correct boundaries.
The data claims to be OSI data, and generalised. If you compare Abbey Island on the ESRI site here with OSM here you can see that it is very generalised and not much use beyond checking topology.
I’d suspect not, both for that reason and that I’d be surprised if OSI data was licenced for use in OSM (but of course I’d be delighted to be proved wrong).
Edit: Both the generalised and the ungeneralised sites are CC BY 4.0, so without a waiver incompatible with OSM.
They also seem to have an ungeneralised version here.
Would it be worthwhile to try and obtain a waiver for this dataset? (And possibly others such as this river network map)
