I tend to disagree: I am not able to verify if this camp is accessible for wheelchair or not, but I could tell that the capitalization of this tag is most likely wrong. That's why I fixed the capitalization to lowercase. This is helpful in that it surfaces this object in whellchair related data outputs which is probably how you found this object as well. So my lowercase tagging update was helpful to surface that there might be a data issue when tagging a prison camp with wheelchair accessibility.

Why did you put the whole tracks of Tehran metro line 1 to railway=construction? e.g. ways way/206878117 and way/206878116 and so on.

This line is open since 2001 and is currently not undergoing any construction work.
Did your survey reveal anything otherwise?

Just looking at the parameters you mentioned it would qualify as commuter rail. But we are mapping the infrastructure and that is one of an express subway line. Everything is prepared for an additional at Vavan intermediate station. Also it was built as an extension of line 1. So everything is subway infrastructure. Following your argumentation the furthest you could go is adjusting the route relation, but everything on the ground should remain as subway.

Half of the buildings you added in nthis changeset are duplicates - from other buildings you added in this changeset as well. If you encounter problems uploading your changes (e.g. connection interruption) you might want to double check that you are not mistakenly uploading the same traces twice.

Most of the residential streets you added are duplicates from a previous changeset of yours. If you encounter problems uploading your changes (e.g. connection interruption) you might want to double check that you are not mistakenly uploading the same traces twice.

Why did you change the tagging of Tehran Metro Line 8 from `railway=subway` to `railway=rail` ? The whole infrastructure was initially built as an extension to line 1 and contains subway infrastructure, from electrification to signalling to rolling stock. Only (express) subway rolling stop in a subway timetable is operated on this track and it is also separated from the Iranian railways network so I can't see why it should be classified as a railway.

Is there a specific reason why you deleted the station node for Shahre Aftab metro station? This is central element of each public transport station.
I wen ahead and reinstated it and added it again to the stop_area relation

The OpenStreetMap project is about documenting geopgraphical information of actual objects in the world. You have added multiple promotions for your Russian Guide services in Tehran which do not have an actual equivalent in the real world. I've therefor removed these wrong tourism information. Please resort to traditional paid advertisting on different channels and do not abuse OSM or Maps.ME for that

Hallo und willkommen bei OpenStreetMap,
Dieser erfasste Friedhof sieht korrekt aus. Wenn du die Möglichkeit hast, kannst du gerne auch die Fußwege dort erfassen.
Ein Hinweis noch: Beim Hochladen deiner Änderung solltest du eine Zusammenfassung angeben, so dass andere Nutzer einfacher nachvollziehen können, was du geändert hast. Aktuell ist diese Zusammenfassung für alle deine letzten Änderungssätze "Bezeichnung des Anschlußgleises". Scheint als wäre dein erster Kommentar einfach wiederverwendet worden.

Subway=yes is part of the public_transport=stop_position to denote which mode of public transport is stopping at this position: public_transport=stop_position

Ja, hab zu schnell geklickt und den vorherigen Änerungssatz verwendet.

Korrekt müsste die Zusammenfassung lauten:
Leipzig, Germany: Fixed turn restriction relation from Kohlgartenstrasse into Dresdner Strasse as well as geometry of crossing ways around tram stop Johannisplatz

"Pokémon Go Treffpunkt" im Leipziger Opernpark: Als ich gestern dort vorbeiging gab es keinerlei derartiges physikalisches Merkmal. Von daher scheint die Einordnung als Touristenattraktion sehr überbewertet. Ich empfehle, dass eher bei einschlägigen Pokemon-Seiten zu bewerben als in OSM

Why did you change the Freeway 9 tagging from highway=motorway to highway=trunk?
It's a motorway with a dual carriageway and no crossings. Also the street signs used are the blue freeway ones and not the green ones for roads with expressway infrastructure.
I would therefor recommend changing the tagging back to motorway.

Wow! Someone has been busy. Great work on quality assurance for OSM data in Iran.

Spam!

Thanks both for clarifying. I've re-added the tagging (even though in lower case fashion). I think we should consider embedding it into the crossing=* theme though, e.g. either as crossing=uncontrolled_välkky or crossing=välkky
Adding a new tag describing the type of pedestrian crossing seems a little overkill.
It would also help tremendously if you would add at least a stub documentation to the OSM wiki so your fellow mappers like me better understand what you are trying to capture.

Hi, Thanks for your comment. To start with the last part of your comment: These are not mechanical edits, instead I review individual entries in Taginfo and correct those that appear to me a mistagged or remove others that look like tagging mistakes or redundant information.

The "Välkky=yes" tagging was added 5 years ago by user "alv" in this changeset: changeset/6342582
The changeset comment didn't really indicate what should be documented by this and it's the only ever use of that tag which leads to believe it was a mistake in tagging. Looking back I should've probably reached out to alv since he is still active, but I wonder if he still remember what he was tagging in November 2011. I've sent him a message to have a look.

My change only removed a "name:françis" key which contained an identical value to what's currently already on "name". So besides the key being in the wrong format (French name should be tagged as "name:fr" key) it was also redundant information.
Can you clarify which "real name" in which language you are referring to that we should find and document for this way?

This southwestern extension of the Mashhad ring road: Are there concrete plans for this? How do you know the actual course of this extension? Would appreciate if you could name sources.

What plans are these monorail construction tracks based on? I have never seen any documentation on them and there's definitely no groundwork taken place yet.
Please do not use OpenStreetMap.org as a database for possible future plans, but only if these plans have been officially commited to.
