Secondary Link between Wharf Street and Sevenoaks Street has been removed. Bing Map Aerial imagery is a few years old. Use Esri World Imagery to see the new roadworks.

Yeah, I had made it the same as the mall next door. I've now changed the mall and shopping centre to corridor.

Thanks

Are my road crossings done correctly?
I could head out again to confirm the alignment for some of the roads (I also need to check some of the house numbers).

For land-use I have followed the wiki page*. Is this recommended in Perth?
Should I attach the land-use nodes to the footpaths? Currently they are mm's apart.

Thanks for pointing it out. I created all the building areas with their respective levels, selected them all and merged them, and added the address to the relation.
Reading the wiki page 'Simple 3D Buildings' and 'Relation:multiygon', the end result is completely wrong. I used the iD in-browser editor.

relation/10843750 - I created two buildings and merged them for the one property. Looking at the result I'm not too happy, it deleted the building tags and just made them a line with the relation outer. I was thinking of changing the type:multipolygen to type:residential, but the wiki page 'Types of relation' only has a few options.
Then I was going to change the lines to buildings again, but the editor is not liking it.

Is there a place I could chat and learn how to do building mapping, so I can fix my mistakes?
