You could use something like https://imgbb.com/ ?

"according to the diagram" which diagram?

If the sign just says left turn only, then it should be mapped in OSM with an only_left_turn relation (and not with a no_straight_on as that is implied already by the only_left_turn).

How is this signposted on the ground? If it says left turn only then it's better to map it as only_left_turn rather than with the no_straight_on. only_left_turn implies you can't go straight or or turn right already.

You can't modify a changeset comment after you've saved it, but you can add a changeset comment like we are doing here. The changeset comment is helpful for others to understand what and why you changed something.

If you check the history of the way you're talking about at https://pewu.github.io/osm-history/#/way/151022092 you can see it was actually created by inas. No worries though.

Looking at the imagery, it doesn't look like there is a physical barrier and as you point out you can still make left and right turns from the Kingsway so you can't delete it otherwise routers wouldn't be able to direct people to make those right turns off the Kingsway.

What you suggest with adding the only_left_turn restrictions on Willarong Rd the way to go. Ideally you'd only add this tag where there is a sign or road marking indicating you can only make a left turn from Willarong.

PS. I also noticed that short segment https://pewu.github.io/osm-history/#/way/151022092 has oneway=yes, which means you can't turn right from Kingsway heading northbound, but looks like from the imagery that you can, so you might want to remove the oneway=yes tag.

The SEO business was removed already in an SEO cleanup, but I've also reverted the part which moved the footway.

+1 with discussing this change.

I tried to document the current situation at
https://gist.github.com/andrewharvey/6c55bff57b96481528cc4da974e69e35

In summary, I'm okay with how it is currently, but still think we should distinguish certain suburbs as higher ranking (eg. Parramatta vs Harris Park)

...aware that @TheSwavu also replied with a direct message. But worth noting that on the way down from the Blue Mountains there is a sign which says "Welcome to Sydney", which would indicate that the Blue Mountains shouldn't be part of Sydney.

I'm torn though, @TheSawvu raised good argements for including Blue Mountains in Sydney. At the end of the day anyone can always create the own polygons including or excluding if they want.

Thanks for contributing.

1. AFAIK this facility is mostly un-staffed so no office here right?
2. An industrial process takes place here so should be landuse=industrial.
3. Add the operator=Sydney Water
4. https://taginfo.openstreetmap.org/search?q=amenity%3Dutility_water isn't used, so I would leave this out. The landuse=industrial + water tanks imply it.

We now have this pub mapped twice

way/518743604
way/535898268

I prefer to map the grounds since someone in the outdoor seating area is still at the pub. So I'd put all the tags relating to the pub on the outside way, and just leave the tags relating to the building on the building itself. That's my preference. Open to what you think.

There are now two post offices here

node/4312386629
way/535847473

There should only be one amenity=post_office since there is only one post office.

I suggest migrate across tags from the node to the way and delete the node.

You could change it to highway=service, service=driveway, access=private rather than deleting, but I'm not fussed.

Perhaps building=retail would fit here since it sells things?

You could just add amenity=atm as a seperate node inside the building, it's more likely to be used by data consumers and you can then add tags specifc to the atm.

There is a bicycle=dismount sign on the footbridge which I've mapped and an arrow on the road pointing bicycles to divert to footbridge but nothing forbidding it.

At the moment routers might decide to skip it since it's dismount and no, but in reality you can ride on the road.

I'm not 100% sure either but I might remove the bicycle=no.

I made some changes to Bennelong Bridge, see changeset/53393819

The road and cycle/foot path are physically seperated on the single bridge. I've changed the access tags for each to reflect. (ie. no foot or bicycle on the road way, only on the cycle/foot way).

Changed psv to bus as it's only busses allowed, not taxis (psv includes taxi).

The access restrictions extend west past the bridge for a little bit.

Any reason way/260879705 was changed to bicycle=no? I rode over the bridge today and couldn't find any signs forbidding bicycles.

I thought way/329309054 had been long overgrown, I'll need to try to follow your path next time!

Just adding the link for fitness station leisure=fitness_station

copied, yes but moved no. moving the tags means removing them from way/461677979. ;)

Agreed all the tags that relate to the building should remain on the way, and all the tags relating to the station should be moved (including deleted from the way) to the node.
