Thanks bhousel and SK53 :)

I am done with all my stadium edits by the way. I'm going to check all my edits for errors, most of my edits which contained errors have already been reverted/adapted. Please give me a little time to improve / revert some of my edits. Only a small amount of my edits still contain errors, I will fix those soon.

Hi, the first row was already included. It was a pedestrian way already, probably because you can walk over the stairs at the lines. I added the missing second and third rows (with the numbers between 200 and 350). I saw that various other stadiums (look at the large Canadian stadiums for example) also used the lines this way, so it's probably okay. By the way, you can also see the lines at Bing.

Do you have some useful YouTube tutorials? I've found some, but not all of those are useful for me.

Thanks! :)

Can you please also check if my last edit at Estadio Campeón del Siglo in Montevideo is fine now? I've changed leisure tag into stadium tag and stadium tag into building tag. Is it good this way?

Thanks again Nuno, I'm going to watch those tutorials. I have a doubt about this one, can you please check if I added "alt_name" the right way at this stadium: changeset/62244989

Thanks, now I understand. "alt_name" is "Mend-A-Hose Jungle" and "name" is "Wheldon Road" is okay I guess?

Thank you!

How can I use building:part?

Hi Alecs01, can you please explain why this can't have a stadium tag? The tag includes the entire indoor stadium.

Hi muralito, thank you for the explanation. Can you please check if my edit of this stadium is good now? I've changed the leisure tag into stadium tag and the stadium tag into building tag. Is it good this way? I understand now that the stadium tag should include the entire stadium complex, with buildings, stands, field, etc.

The stadium itself reads the stadium name:

I've reverted my edit, I've changed the stadium complex into "stadium" tag and the stadium building into "building" tag. Can you please check if I did this right?

Yes, because it is not named "Palais national omnisports". If you translate "National Indoor Stadium" you don't get "National Omnisports Palace". Shall I add the right French name for this stadium?

Yes it is an indoor stadium. I've changed it back into "building" tag, if you think that's better.

By the way NunoCaldeira, can you please explain "adding a pitch (which becomes hidden due to the lack of building inner)"? How can a building inner be placed the right way? If I know this, I can fix my edits with this error. I saw some pitches indeed aren't visible. I can't find the answer on the OSM Wiki.

Thank you very much for the explanation, now I understand. I'm going to change my edits with wrong tag names (most of those seem to be already reverted I see).

Thanks. Can you please explain to me how the alt_name can be added? I can't find it over here: alt_name=*

Also please keep in mind that only a small amount of my edits contained deleted objects (almost all of those have already been reverted). At MetLife Stadium for example, I deleted hundreds of very small objects (yes that was stupid of me). Those have been reverted, and after that I changed the Giants Stadium the right way. This way, it looks like I deleted objects at hundreds of stadiums, but that's not the case. Only at a small amount of stadiums I deleted (often a lot) of objects, those have already been reverted and after that my edits at those stadiums were fine. Here you can see MetLife Stadium, I've made most of this stadium: osm.org/search?query=metlife%20stadium#map=18/40.81352/-74.07435

I've added most of those stadium sections with numbers.

If I find a stadium with missing stands, a missing or wrong stadium name or something like that, is there someone I can mail who can do the stadium edits?
