@Stereo I am infamous you mean.

I do not really propose to delete anything from OSM and please be aware that in the vast majority of cases a 1911 ED is still a 2022 ED and that boundaries have not changed since for most of then, but I propose to 1. ...systemically...clean the data up tagging wise while in situ. 2. decide what boundaries we want to 'archive and what we want to keep' ...and why and 3 ensure that any boundary that we remove has a home to go to ,..EG to OHM . This is a complex issue best left to a working group and anybody contributing here would be equally welcome in any such group which has to act transparently and fairly and which has to satisfy OSMUK and OSMIE both

The end result should be a fully consistent NUTS/LAU stack which is what admin boundaries are. A consistent political stack is needed in parallel, perhaps a soupcon of arcane ones like Civil Parishes and the rest are history.

An admin boundary is _always_ current and everything else is boundary=historic. However EDs are not admin boundaries in NI. Even worse...the nomenclature itself forked c 1993 with DEDs becoming EDs in the south from that time. EDs created since 1983 in the South, as a City boundary revision for example were never a DED but the vast majority are.

The same principle applies to constituencies, the current ones are boundary=political and others are also historic. I am not aware of the status of civil parishes in NI but they are still legally extant down here as are baronies.

Cleaning all this up will take some time and I pinged Mackerski to weigh in. It has to be dealt with soon as JOSM generates too many validation errors now because of this boundary profusion and this is an obstacle to good editing.

My last mesoscale task was 3 years back when i did local electoral boundaries and i had nothing like the errors i see nowadays, sometimes 100s, almost all boundaries.

If they were simple then Poor old Dermot wouldn't have agreed to chair a working group on the issue. There is a profusion of historic boundaries ...some of which have not been abolished in law since the foundation of the state over 100 years ago and they may well need excision from the base map and a bulk import into openhistoricalmap instead along with a tagging exercise to clean them up a tad.

The current profusion causes an undue amount of JOSM validation errors for my taste. It is a hindrance to the betterment of the actuality...to coin an aphorism.

That would be my preferred solution anyway if Dermo reaches out for a natter on the matter. @RoryM may wish to bulk import them into his invaluable townlands.ie site at some stage pre or post tag cleanup as well and I always defer to Rorys wishes.

Admin Level boundaries should be unique and should be part of the NUTS/LAU stack for a territory. Brexit won't change anything other than the names of the statistical codes...whenever they get around to that.

This is the NI stack

and the lacuna in NI is that EDs were abolished in 1923 and replaced by similar "Wards" . Tagging EDs with admin levels is incorrect These wards are the correct LAU2 / Admin Level 8 or 9 entity for NI. However as the EDs were used for census data in NI as late as the 1950s the EDs should be converted to boundary=historic from boundary=admin, admin level deleted and from dates of 1850 to date 1923 added. I'll leave that lacuna to my colleagues in NI and they are welcome to contact me on the subject any time...the lacuna has been discussed on talk-ie going back to around 2014/5.

Separately I see that OSMF Ireland is intending to convene a Boundaries working group under @Mackerski but I have not heard anything about its activities...glad to help there if asked. See

I have been on boundaries for a long time.

I didn't get any message, maybe only the comment creator does.??

@SomeoneElse @Boggedy test notify

I found there were 2 sets of EDs in Donegal or more properly 2 sets of admin_level=9 boundaries where there should only be one. Every part of the land area should also be part of an ED ...right out to the middle of Lough Foyle.

There is a separate problem in NI ....they have not had admin_level=9 status since 1923 but at least they are not duplicated there.

I dont know why, JOSM did something odd

Dunno what caused this, I was editing in Somalia not in the Artic. Some odd JOSM behaviour.

Warin61 I agree with you, it is natural

Frans S . We were even asked in the instructions for #hotosm-project-5234 NOT to do roads but as the road network is such crap I felt I had to at least connect urbanisations (villages) to somewhere logical. So did you for that matter.

This is the fault of @Russdeffner :) who told us that:

"Project Specific Mapping Notes
The road network in Luzon is 'good enough' for now, please concentrate on buildings for this project."

Frans S . I would have thought residential was in a town and unclassified was extra urban even if part of a road were in a town,

Normally businesses locate on extra urban roads and therefore they are not residential but mixed.

residential roads would be no business or industry

@Frans S . here you see I made the road unclassified as it is in the middle of the road network

I dont download gpx tracks no

Well. I would normally tag unclassified but this is on the west edge of a large national park so I am assuming it is not a through route. Were I to find that between 2 towns I would make it unclassifed but it is the 'edge' of the road network, so!

Quite right. You can flag up any maxspeed in Ireland not ending in 0 in fact. Fixed Gerd.
