Hi, just saw ur query on wiki. As you can see with most of the map, the house number is added to the building as part of the building address instead of entrances as there are likely multiple entry points to a building.
You can crosscheck the house number with the Singapore OneMap overlay (which also puts the house number in buildings) but the one used for osm iD might not have been updated with the latest version on the official gov website so newer buildings might not show up
Hope this helps

Yes, the PIE exit is closed/rerouted. But you have edited access tags along Thomson Road which is still open. I've reversed this changeset

Hi there, I've noticed that several of your edits have street names in ALL CAPS. Please fix and capitalise correctly (i.e. Telok Blangah Road) Thank you

Can someone revert this node (1838456031) to the previous version? One of their previous edit (Changeset #136863665) moved it and it is definitely off. It is at Singapore Changi Airport T2 and I've added a note on the map as well

Hi there, I've noticed that several of your edits have street names in ALL CAPS. Please fix and capitalise correctly (i.e. Tampines Expressway)

Please use "Street" instead of "St" and FYI link roads are usually not named

Hi, this is the link road from the expressway. Please fix your edit. What you have included is an address

Hi there, we usually don't include names on slip/link roads and do not use abbreviations like. Use "Avenue" instead of "Ave"

Fixed it and renamed the roads to Woodleigh Underpass, Braddell Road and Bartley Road accordingly

There is already a right turn from Bartley Road to Upper Serangoon Road. The way you drew is from the underpass section that goes under Upper Serangoon Road and does not intersect with it.

Hi, there is already a right turn so I'm not sure why you are adding a right turn that does not exist from the underpass. Please delete it

There's abt 200 duplicate ways that needs to do deleted (prob all the v1 ways in this changeset)

Can someone revert the edits? There's too many duplicates to delete and fix manually.

How abt the bus stops? They're gonna need to be shifted as well right?

Might not be super accurate due to terrain height differences

the islands didnt even exist until mid-late 1990s

If you looked at historical maps of Singapore, when the islands were first reclaimed, they weren't linked. Think it was only when they dammed up sungei punggol that the islands where connected

Hi there, noticed u used 'name' instead of 'addr:housenumber' for the block number. Also suggest editing the geometry that's already mapped replacing it with a new one since you also accidentally removed other info and tags

The buildings for the following residential areas seem to be slightly offset from actual location based on 'Singapore OneMap' overlay: Woodlegh Glen, Woodleign Hillside, Alkaff Courtview, Alkaff Lakeview, Alkaff Oasis and Alkaff Vista
