Searching for UK subdivisions polygons in poly format
Hello
I am searching for for UK subdivisions polygons in poly format as it can be selected on Polygon creation page.
Many of the counties cannot be found at OpenStreetMap Nominatim_ Search.html. I would prefer one page, where everyting is available.
Does such a site exist?
Sincerely Peter

Re: Searching for UK subdivisions polygons in poly format
Hi, welcome to OSM. This forum gets very little traffic. You may be better asking on the talk-gb mailing list.
I am not sure what you mean by poly format, but I am a little concerned that counties cannot be found. I am fairly sure they are all in OSM.
Can you give some examples of those that are missing?
Cheers Phil

Re: Searching for UK subdivisions polygons in poly format
Thank you for your answer,
Poly is one option on the polygons.openstreetmap. Others are WKT, GeoJSON, poly
I have the following lists of counties or regions from Wales, see here:
https://en.wikipedia.org/wiki/Preserved … s_of_Wales
Clwyd
Dyfed
Gwent
Gwyedd
Mid Glamorgan
Powys
South Glamorgan
West Glamorgan
But most of them cannot be found on the page: http://nominatim.openstreetmap.org/search

Re: Searching for UK subdivisions polygons in poly format
I suspect that the problem is that Nominatim only deals with current admin divisions, not historic ones.
Also, I'm not sure what you mean by "the polygons.openstreetmap"?

Re: Searching for UK subdivisions polygons in poly format
Taking a well-known location in what was formerly Gwent http://www.openstreetmap.org/search?que … 1&layers=H (the Celtic Manor, a.k.a. Colditz to the locals) Nominatim thinks that is "Resort Hotel, The Coldra, Coldra, Newport, Wales, NP18 1HQ, United Kingdom".
The name "Resort Hotel" is I suspect something descriptive that someone has made up, but the rest is correct. Wales has unitary authorities so there is no Gwent council any more. Wikipedia has the details at https://en.wikipedia.org/wiki/Gwent_%28county%29 .
The preserved county appears not to be in OSM (see https://taginfo.openstreetmap.org/search?q=Gwent#values ), probably because it doesn't exist any more (although some other historical counties are in OSM)
If you really want the geometries for historical counties you'll probably need to get them from somewhere else but are you sure that's really what you want?

Re: Searching for UK subdivisions polygons in poly format
Hello,
Thanks for your answer. But what I really need are administrative regions, which are actual. Where can I find them?
I do not want historical regions at all.

Re: Searching for UK subdivisions polygons in poly format
I'd suggest https://wambachers-osm.website/boundaries/ . You can open up UK, then Wales, and select the boundaries you want. See also https://help.openstreetmap.org/question … rom-of-osm and https://help.openstreetmap.org/question … 6287#46287 .

Re: Searching for UK subdivisions polygons in poly format
You can easily create poly files using the josm plugin; and there used to be one for QGIS too.

According to the document you quoted that list is the 1974-2006 list.
The table 'Wales - changes of 1996' indicates for example that Mid Glamorgan was split between Merthyr Tydfil, Rhondda Cynon Taff and Vale of Glamorgan.
The current divisions are the right hand column of that table.
