Hi, I reverted this changeset because you connected a footway to a powerline.
You need to add the footway again by zooming in much closer so that you connect it only to the footway.

Hi, this building appears to exist on the latest imagery, Esri. Are you sure it needed to be deleted?

Hi, you deleted part of the boundary relations for Mount Druitt and
Rooty at the junction of Duke Street and
Woodstock Avenue.

I have fixed both relations.

Hi, unsure why this was a multipolygon.
https://tools.geofabrik.de/osmi/?view=areas&lon=115.81559&lat=-31.91664&zoom=19
It grouped two different addressed buildings together in a mp and was not constructed or tagged correctly so I deleted the mp.

Hi, multipolygons can't have duplicated sides like this

I have fixed

Hi, you created an invalid wood multipolgon. Outer rings cannot join each other. I changed it to a simple polygon for the whole area as there appeared to be no differentiating tags to keep as three sections. If you still want them as separate areas then use three simple polygons which can share sides.

Please read the osm difference between a hospital and a clinic
amenity=hospital
I have changed to a clinic

Multipolygons cannot have shared edges. fixed.

Multipolygons cannot have shared edges. fixed

Another alternative is to construct them as TheSwavu has done, making a mp of each part and reusing the common section in each mp.

Osmi detects these mapping errors

Hi, you are creating invalid multipolygon relations. Our wiki has extensive documentation on multipolygon validity.
Outer rings of mp cannot share sides.
You should just use simple polygons for these type of buildings or use the building:part method where you would draw a polygon around the outside perimeter and then draw the individual sections as building:parts. These are especially for representing buildings in 3 dimensions but can also be used for simpler mapping like this.

Name is not needed, addr:housenumber = 103 is sufficient

Hi, I reverted your changeset because it is probably easiest for you to add a new node within the building boundary and add all the business tags to that.

Hi, you appear to have added the business details to the entire building but PSQ Group as located by their website only occupy a portion of the building…. Level 2, 200 Adelaide Terrace, Perth.
You should leave the outline of the building with only tags applicable to the building.
The business details should be added to a separate node within the building outline and all it’s tags added to that node.

I have fixed up the data that @22040316 left for us to quality control.

Hi 22040316
I see you have moved on to mapping in a different country now.
Can we expect you to fix the changesets as commented upon east of Melbourne?

I notice some of the building near the corner of Hayfield Road and Milloo Crescent have their right side cut off where aligned with edge of your data.
Do you intend to return to each of these dumps of data and fix up such errors?

….also the name=Footpath needs to be deleted.

Hi, you have dragged a node on Stephensons Place. Can you correct that and also remove the name=Residential Dwelling tag on all the houses.
The name tag is reserved for things that really do have a name as described in our wiki.
