Hello! This looks very much like a mechanical edit. Have you read osm.wiki/Automated_Edits_code_of_conduct ? If so, where did you communicate the change that you were going to make?

It appears that some of the data in this changeset hasn't had even a cursory check. See for example node/3984337590 .
You also might find it helpful to read osm.wiki/What's_the_problem_with_mechanical_edits%3F .
Best regards,
Andy

Re the rail usage, what you've mapped is incorrect (I was there on Saturday and will update when I get the chance, with source details).
Please don't guess if you're not sure - instead add a note, and local mappers (who actually go out and survey things!) will check on it. If you guess (a) the map is wrong and (b, even worse) we won't know the map is wrong.

Hello micha_k,
This looks very much like a mechanical edit (see osm.wiki/Automated_Edits_code_of_conduct ). Can you please explain where you discussed them beforehand, and also what source you used for the change in each case?
In previous edits near me (changeset/38239352), your changes have clearly not been influenced by the actual situation on the ground.
Can you please explain how this changeset is not subject to the same problem?

Hi,
Please don't add test data to OpenStreetMap. It's a live server, and it is supposed to represent the real world as it exists.

If you want to test the API out, there's a server over at http://api06.dev.openstreetmap.org/ that people have used for testing.

Best Regards,
Andy

Oops - something at latitude 0, longitude 0 got added here. I've deleted it.

Just wondered if the note "please leave at layer 3: if rendered as an area at 0 other important layer -1's disappear" was still true (for any renderer) - a lot of water has passed under the bridge since then?

Looks like someone's fixed it by deleting the offending node - see changeset/38410242 .

Hi - thanks for fixing this!

It wasn't quite 2 years, thankfully, but it was a month, which was a surprisingly long time. The problem was the drag of this node node/2483812419/history . Unfortunately when a node is moved but there's no change to the ways it's part of the history of the way doesn't get changed, so you can't easily see the change.
Thanks again,
Andy

In this set of changes there are only deletions. Can you explain?

Hello and welcome to OpenStreetMap!
I notice you added way/406805813 as an area (there was a large, fairly inaccurately drawn building that someone had added ages ago underneath). I've changed this to be a separate building now. Also - if this is the one called "Finsbury Dials" then you can add that name to it if you want.
Cheers,
Andy
(hope you don't mind me mentioning this - just trying to help. Any questions please don't hesitate to ask).

@Ginaroz the comment before yours looks like spam - I'll hide it.

For info, in case you haven't seen it, https://help.openstreetmap.org/questions/49058/rendering-of-lakes-on-garmin-devices .

This is a changeset with a very large area, and "remove self intersection of area" does not actually describe what you actually did.
Would it be possible to describe the actual changes made and why you thought that they were necessary?

Have you thought of asking the people at http://www.peakrail.co.uk/ ? They should know which bits are "theirs" and which bits Railtrack's.
Logically I presume that way/359980269 only exists to stop anything from Peak Rail getting onto the Railtrack section. Since Peak Rail is still all semaphore signalled, I'd be surprised if there was any sort of train protection system in place on it anywhere.

Re the fixmes of "Should be rechecked whether service=yard or service=siding" here, how would I tell as someone walking past what should be tagged as what?

Re the wiki sidewalk page, it's wrong. It's a wiki; if you think it's important, change it. Personally I look at what tags mappers actually use rather than what one person wrote in the wiki 4 years ago. There are many places where the wiki is wrong, irrelevant or simply does not get the nuances of various possibly interpretations across. It's not possible for one person to fix them all - it would be a full-time job as per https://xkcd.com/386/ .

Hi,
Something went a bit wrong here - you added a node at latitude 0, longitude 0. I've deleted it.
Best Regards,
Andy

Before "roadside footpath" tagging (footway or sidewalk) was widespread in OSM, the "footway" and "sidewalk" tags were used pretty much equally. The British English words for "the place where you walk beside a road" (OSM uses British English rather than American English) are "pavement" and "footway" and so would normally one of those would be the tag to use, but unfortunately both have other meanings e.g. in American English. That's why most people use "sidewalk". I'm not sure where you get "sidewalk=no is preferred" from - taginfo shows that it clearly is not.
With regard to the service=/usage= tagging, if you don't know what the rail lines here are used for, how can you know what tagging is correct?

Was the import of wikidata items worldwide discussed anywhere? On https://lists.openstreetmap.org/pipermail/imports/ I can see mentions of the UK and Ireland, but not elsewhere?
Who's cross-checking the data added, especially in places where there probably aren't so many local mappers, such as North Korea?

Hi - any reason you've changed footway= to sidewalk= on the roads here? It's not wrong, but they mean the same thing...
Also why "sidewalk=no" rather than "sidewalk=none" on way/115930683/history ? http://taginfo.openstreetmap.org/keys/sidewalk#values suggests "=none" is the more popular by some margin.
Also are you sure that way/359980268/history is "non-preserved" and yet the southern one isn't?
Cheers,
Andy
