Lola Fox (2025-11-20 18:50:40+00:00): Yes, I know it. Where would be the one member relation?
GBAB (2025-11-21 07:45:06+00:00): E.g. these are multipolygon relations with one and only member:

https://www.openstreetmap.org/relation/19857249

https://www.openstreetmap.org/relation/19857252

They can stay alone as simple features (ways) whithout making them relations.
Lola Fox (2025-11-21 09:28:04+00:00): If an area is INNER you should put it in a relation, don't you think?
GBAB (2025-11-21 10:10:25+00:00): No, definitely not.

Now, you have a multipolygon with another multipolygon as an inner member. This is absolutely not necessary and just makes things more complicated.

The solution is to have a multipolygon where the inner member are simple ways (areas).

For more information:
https://wiki.openstreetmap.org/wiki/Relation:multipolygon

(Or just look some multipolygons on OSM.)
Lola Fox (2025-11-21 13:15:00+00:00): that is, the inner relationship is not there?
Lola Fox (2025-11-21 13:17:00+00:00): here the inner relationships are expected https://wiki.openstreetmap.org/wiki/Relation:multipolygon
GBAB (2025-11-21 14:53:20+00:00): Can you specify more exactly where you can find it on the wiki site? It is a bit long…

Anyway, inside a multipolygon is not needed any additional relation. One or more simple ways are fairly enough.

Look e.g. here:
• https://www.openstreetmap.org/relation/1775846 or 
• https://www.openstreetmap.org/relation/1775847

They consist of two ways and that's it. No additional multipolygon inside the multipolygon.
Lola Fox (2025-11-21 15:30:53+00:00): To make things quicker, can you fix that pool so I can see the fix later?
Lola Fox (2025-11-21 15:31:11+00:00): and let me know
bxl-forever (2025-11-19 22:27:10+00:00): Hello,

With respect, the two crossings below do not have any zebra markings.  We are speaking of the node where the sidewalk must cross the yellow cycle tracks.  We tag those with highway=crossing + crossing:markings=no.

https://www.openstreetmap.org/node/6982830098
https://www.openstreetmap.org/node/6982830102

Thanks for adding Mapillary links to every of those objects.  If you inspect them, you will find out that there are no zebra markings here.

I will fix your edit for those two.  The other nodes seem correct, though.
Glassman (2026-01-22 20:05:46+00:00): You renamed a section of the way that previously West Saint John's Road as North Saint John's Road. Do you have data to back up the renaming?
MassCartog (2025-11-20 03:26:52+00:00): Hi welcome to OSM. In this changeset you removed a bunch of buildings, could you explain what you are doing? The building outlines should only be removed if they are have been removed and dont exist any longer.
DWA60187 (2025-11-20 19:41:51+00:00): Oh I did not mean to remove buildings....so sorry. I was just trying to remove the businesses names that were with it. We are not wanting those to show on the online directory
MassCartog (2025-11-21 14:37:44+00:00): Thanks for the reply unfortunately it was kind of hard to figure what you intentionally removed and what was unintentional so this whole change set was reverted.

Feel free to take another shot. So only remove tags that are untrue now, like places that have gone out of business. Don't remove anything that still exists on the ground. If buildings have not been demolished, keep their outline and the tags that show their address information. Thanks!

Your mappings are rather accurate; however, you included the shadow of the building in your mapping. These are no part of a building.
Best regards,
Norbert Dichter (2025-11-20 14:37:14+00:00): Hello, thanks for mapping and welcome to HOT. Thank you for your contribution. The buildings you mapped are well done as to their location. But pay attention to the squareness of the corners. Always draw buildings as square and precise as you can. Then add the Building feature type. And last, right click it and click the square icon. Or just hit the Q-key.
Also please keep in mind: many buildings are very close but do not actually touch each other, try to map them close to each other without letting them connect or share nodes with each other, roads, or residential area outlines. In the iD web editor, holding down the "alt" key will keep nodes from "snapping" to each other and accidentally connecting.  Thanks so much for your contribution, Norbert 'Nodi' Dichter, HOT validator.

Gregory Peony (2025-12-05 02:15:49+00:00): Thank you for your contribution! 

All footprints you mapped here represent buildings, though they could be more accurate.

When mapping buildings, please trace the shape accurately. Accurate building footpritns aid population estimates and prevent issues like data overlaps. Zoom out to obtain the orientation and shape, then zoom in so that you can accurately draw the footprint. Exclude shadows and yards when tracing the footprint. Keep in mind that you are looking at the [roofs of buildings](https://wiki.openstreetmap.org/wiki/Key:roof:shape#Roof_shape), but mapping their footprints. Depending on how the scene is lit, pitched roofs may have light and dark sections that belong to one building. Generally pitched roofs overhang the walls of a building, so a footprint slightly smaller than the roof is accurate. You can scale selected features in ID with `shift+(-/+)`, or JOSM with `ctrl.+alt+Lclick & drag`.  Take care to make contributions that others can build upon.

Please do not connect the corners of buildings to other buildings or features such as highways or residential areas. In the iD Editor, hold down the `Alt` key to prevent your cursor from snapping to existing data and accidentally creating shared(grey) nodes. This [video about connected nodes](https://youtu.be/ltn1VOiq5_0) has more information and a guide.

After tracing and tagging features which are likely square or round, please remember to square their corners `q`, or circularise them `o`, because it is almost impossible and time consuming to draw shapes so percisely manually. Buildings with metal or pitched roofs tend to have square corners; round buildings are identifiable by the distinctive cresent shaped shadow they cast. Unless the building is clearly a different shape then it's best to assume that it should be rounded or its corners should be squared. In the ID Editor, you can `right click` for access to editing functions. Since roofs tend to overhang walls trace the initial shape slightly smaller to allow a buffer for any change in size which may occur. In JOSM use the [buildingstools plugin](https://wiki.openstreetmap.org/wiki/JOSM/Plugins/BuildingsTools). In ID you must draw the shape accurately enough if you want every corner to be squared. This [video about squaring features in ID](https://youtu.be/Xs5wX592E1o) has more information and a demo.

Keep on mapping!

The change to https://www.openstreetmap.org/node/12818283033 seems wrong as the library's clearly in Illinois.
catsparrow (2025-11-20 19:17:01+00:00): Thanks for the catch! I must have had all my data layers in JOSM merged into one, so I had Illinois & Indiana on the same one.

I inadvertently bulk-changed addresses from IL -> IN. I have reverted the appropriate changes.

Taya_S (2025-11-20 06:05:42+00:00): Reverted incorrect reversion. This changeset accidentally restored the vandalism.

I noticed a few unintended crossings between roads and/or between roads and buildings in this changeset. This usually happens when geometry snaps incorrectly.

In total, I detected 27 potential crossings.

Problematic elements (top 3 by category):
- https://osm.org/way/1186431352 | crossings=15
- https://osm.org/way/103732546 | crossings=10

Would you mind revisiting those areas?
