Hi, I messed this up with a changeset by stadiaarchadia. LOL. Do you know how to revert this one correctly?

I decided agains reverting because of the history of the nodes was only v2 and your edits was an improvement after all. I changed it further and the area around it.

agreed.

From now on I recommend you to begin writing blog articles (se your profile on osm.org and click "my diary") or write to a talk-mailinglist when you have questions and lists like these.
I'm going to revert the change to this stadium now because of all the deleted nodes.

Adding simple stuff like buildings specifying the source is fine by me.

Hi, corfede, there are no deletions in this changeset.
Here nested polygons are needed to accurately describe the area. See osm.wiki/Relation:multipolygon#More_examples
Polygon 1: stadium outer, inner.
Polygon 2 inside 1: outer=stadium inner (turf), tennispitch inner.
THIS IS ADVANCED EDITING. If you want to try, ask your mentor.

Regarding your long list of notes I would like to say that your are in NO way required to follow up on you own notes. I leave a lot of notes around and if nobody else sees to them I eventually come around (sometimes years after) to fix it myself when I feel confident about how to do the edit correctly.
I see the notes as a gift to the community. Not an obligation that must be met by anyone.

Congratulations on finding a mentor! :D
I see you have not edited for two days, thanks for listening to my request.
Good luck with mentored editing going forward. You will probably soon be able to teach me how to edit better when you have got the hang of it. ;-)

Hej, tack för svaret.
Ingen fara. Jag har mappat i flera år och först upptäckt det med att spara historiken nyligen. Hoppsan.

Toppen. :)

Tack för ditt svar.
Det är särskild viktigt att du är försiktig och lämnar utförliga kommentarer om du tar bort nått eller är osäker på vad du gör.
Ok?

What did you remove here?

Tack för ditt svar.
Jag skulle vilja att du är noga med att skriva ändringskommetarer så vi andra ser vad du gjort.
Jag ser att du tagit bort noder som har upp emot 5 versioner. Jag skulle vilja att du sparar noderna så som förklaras i länken ovan.
Mvh
Egil

Hi :)

Thanks a lot for changing your strategy to asking first.

The key to succes with this is JOSM. Install it now, then read on.

Looking at your posts I see a lot of notes. I looked at a few.
Let me take an example:
1) Stadium in Silkeborg
osm.org/note/1522313#map=19/56.18424/9.57528&layers=N
You correctly noticed that the pitch was missing from the stadium and added it with this edit 7 days ago: osm.org/way/623566222/history
BUT
To as you correctly state this data does not show on OSM Carto (default map on osm.org) BECAUSE it renders in layers. In this case it renders the pitch FIRST and the stadium on top SECOND.
Do you understand?
To see this you need to click the arrow with a questionmark and click the map.
So how to fix this?

Method no.1)
Force the pitch on top with layer=1. This might work
or
Method no. 2)
Select both elements in JOSM and choose edit->create multipolygon. The stadium is outer and the pitch is inner.

Method no. 3)
Add way where the stands end towards the pitch (this is not a rectangular way as it follows the round corners of the lower part of the stands. Select this way (role=inner and the outer stadium and pitch (inner) and ->create multipolygon.

Toppen, tack för svaret. :)

Hej. Kan du utveckla?
