Multipolygon outer way shares segment with other ring (2)

That has nothing to do with crossing ways. It has to do with "shared segments"

Why is this water way a multipolygon? Relation: 13470856.

The relation has 4 members that join to from a continuous closed way .. yet the roles for the members are both 'inner' and 'outer' which is wrong.

I have combined these into ONE way and put the tags on that way .. and deleted the relation.

The geofabrik runs ~every day .. so you can check it about a day after you make changes to see. The JOSM validator also does some checks too .. see if you have any errors or warnings there before you upload the data to OSM. .

Hi,
A relation's outer way should not cross the same relation's other outer way.

See https://tools.geofabrik.de/osmi/?view=areas&lon=115.51391&lat=-32.00749&zoom=18

Suggest the gun is not a bunker and should be tagged as such.

An 'inner' cannot touch an 'outer'!

I leave you to fix this one.

This broke the beach relation!

An 'inner' cannot cross an 'outer'.

Corrected. Rocks now more detailed. Beach extended out to sea - beyond hi water level. There are more rocks that can be added .. if you want.

Thanks.
I keep an eye on the area errors and the public transport route errors.Started so I can pick up my own errors - usually relations, but I now try to keep the general Australian errors down. Where it is a new mapper I usually fix it myself - we all need time to learn. Where it is a more experienced mapper I tend to let them know of the error, particularly where it is repetitive.

Hi,
You would have had a warning message about 'self crossing ways'. These should be fixed before uploading.
Please see https://tools.geofabrik.de/osmi/?view=areas&lon=145.90375&lat=-41.06388&zoom=12

There are some 5 errors there now, there maybe more as the QA tool sifts through the data to d=find more.

I have checked 2 of them and in both cases you are the author of the errors. Please fix them.

The 'Bruce Highway' incorporates many roads with different names - e.g. Yamba Road. This does NOT mean those road names are added to the name of the route.

Kunwarara Rd removed from route name.

I have done a few where they cross a 'road' (alley).

Good luck .. it won't be 'nice'. Possibly select all buildings with you as author (should be able to do that .. but I don't recall the magic potion) and move them as one lot. Then check them at various places.

Hi,
This playground does not appear to be located within the arena.

Deleted. Suggest a survey, possibly it refers to a number of playgrounds, with age limits?

Error! This is actually Burnie Tasmania!

Yes the buildings should have been referenced to the roads locations. Now many roads are crossing buildings - mess!

Hi,

Using JOSM validator there appears to be a lot of errors/warning here.
See https://tools.geofabrik.de/osmi/?view=areas&lon=115.80982&lat=-31.94067&zoom=18 for a small sample.

No.

It is not a multiplygon.. see https://tools.geofabrik.de/osmi/?view=areas&lon=115.80982&lat=-31.94067&zoom=18

Simplest solution - retrace the outline.
? Is the outdoor seating on top of a ground floor ... or is it not really part of the building?

Hi,

The relation/13437361 has errors.
See https://tools.geofabrik.de/osmi/?view=areas&lon=141.98260&lat=-33.04930&zoom=14

Hi
relation/13431424 has two shared segments - against the 'rules'.

Hi,

layer=0 is unnecessary and will be automatically removed by JOSM validator tools.

The route relations for Sydney XPT, North West Explorer, North Shore & Western line have been repaired.

Hi,
Welcome to OSM.

If these buildings are houses then building=house would be more correct.
