Not iD/JOSM but that OSM Inspector website...

And also the OSM wiki says
"Anything that is not a valid multipolygon according to this standard (e.g., polygons with intersecting rings) should also be considered an invalid multipolygon relation"
see osm.wiki/Relation:multipolygon

Look at the history of the way to see who really added what?
way/604295549/history

I added no tags to the way, I simply restored the way from a deletion. You can see this if you look at the way history.

Don't think your note will attract much attention. Making comments on the appropriate changeset should get more attention and probably better information as to the present status. This is not the changeset that introduced 'construction' nor 'access=no' etc...

Hi,

You have created a duplication of the river ...

Suggest you delete this one Machchhu (14759437, v2)
and retain the older one Machchhu (227972084) v28

Hi again,

Same problem with relation/14867988 scrub.

I reverted the deletion of the way - the tags there will have to be discussed with those that put them there.

Given that some money was recently spent on the bridge and it was just reopened for the festival, I would think there would be fair pressure to restore it. It may take some time for the determination of what is to be done (restricted numbers?). In the mean time access=no should dis-wade routers as would highway=construction. I'm not certain about the bridge=yes ... Andy Malbert thinks there are enough remnants for that to be ok, I'd like to signify it is 'damaged' .. possibly a new life cycle prefix .. could also be used for damages by floods/fires/landsides/earthquakes...

HI,
This changeset has been reverted.

The way contains some history and should not be deleted . Some elements of the bridge remain. The local mappers have already tagged it access=no and construction.

Hi,
The multipolygon 14786426 scrub is not correct.

Multipolygon outer ways cannot share segments. See https://tools.geofabrik.de/osmi/?view=areas&lon=151.42202&lat=-33.30793&zoom=19&baselayer=Geofabrik%20Standard&overlays=duplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways%2Cduplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways

I would delete the relation and simply place the tags on each way.

Good .. umm how? Sometimes I don't want to change the 'other things' and sometimes I do want to change the other things .. but getting any associated features could be a good step.

JOSM has a 'download along' thingy (under the file menu IIRC) . I have been using that sometimes .. depends on what I'm doing.

Hi,
Relation 14744556 - 'South2' parking is faulty ... similar to the last one ... outer ways sharing segments... as it is mapped there is no need for this to be a relation at all. Simply map the outside way and tag that simple way as parking.

Note a Quality Assurance too identifies these errors, that is how I find them. See https://tools.geofabrik.de/osmi/?view=areas&lon=151.12208&lat=-33.78372&zoom=12&baselayer=Geofabrik%20Standard&overlays=duplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways%2Cduplicate_node%2Csingle_node_in_way%2Cduplicate_segment%2Cway_in_multiple_rings%2Cintersection%2Cintersecting_segments%2Cring_not_closed%2Ctouching_rings%2Crole_should_be_inner%2Crole_should_be_outer%2Cinner_with_same_tags%2Cways

Hi
The 3 pitches you have as 'field_hockey' .. nup .. that is futsal. Fixed. The pitch encompassing the 3 futsal is probably field hockey..?

Few things are 'perfect'.. the map is a guide.

Hi
This dragged some nodes of at least one building out of their true position..

Nodes 5396365685, 5762715185 and 5762715180 - these have been restored to their previous positions.

Hi,

The parking relations for 'London Bridge' ...
relation/14741147 outer ways share segments... that is an error .. and then I'd not think the parking area is named 'London Bridge' .. that is some other feature.
relation/14741146 duplicates 3 of 4 ways ... of the above relation ..

What I'd do ... delete the relations. Tag the 4 ways as parking and be done. Simple is better. May want to check there are no duplications of the ways too.

Hi
relation/14747572 is in error - the outer ways should not touch. I do not see this in imagery.

Way: 1024120367 building=yes, layer=-1 .. NO!!! this is not a single building and it is not underground. Layer=0 is taking as 'ground level'. The buildings are at ground level as are the roads... Please redraw the individual buildings, some share walls .. but that alone does not make them the same building.

Hi
The wetland relation/13478309 has an outer within an outer... and that is a problem.

The DCS Base Map shows more of it as wetland.. possibly a broader brush? In any case the relation needs looking at.

Hi,

The 'east 2' car park relation is not correct. The 'east 3' car park relation is correct.

A multipolygons outer ways should not touch one another - that is the problem with the 'east 2' car park relation. Solution - make one outer way around the outside of the thing. Then make 2 inner ways for the trees ... job done.

Hi
If you use the DCS Base Map you can find the names of these .. tracks.. highway=track for these - dashed lines on road = track, solid lines on road =unclassified.

Boundaries of National Parks, State Forests suburbs usually have no 'on the ground markers' but they are hand things to have on the map .. so you can tell when you enter one, or leave one.

The area could be a legal easement for something.. road, electricity line, gas line .. even an old stock route..
There is no road there..

In id you should be able to select various satellite imagery as a background .. is that what you mean by 'photographic view'? This image is a 'map rendering' .. and it is the 'standard OSM map' changeset/128033403#map=19/-32.5543951/117.320466

That data set has no road information...
Someone has linked a road to It?
Can you tell me where it is?
Use the map and pan around (you can zoom in/out) then zoom in and use the '?" button on the lower right of the page and click on it to get the thing your interested in .. Open this webpage
way/963923971

Here you can see the boundary was entered by 'TheSwavu'.
