Yes, the filter was moved today

Good point. Probably remove the inner/outer relation from the building (and put the tags on the outer way) then mark the quad with layer=1. Or some more complicated building mapping, that I've never really understood!

By the way, Welcome to Openstreetmap! Sorry about the briefness of my comment last night, I had a lot on, and just fired it off without checking any more about it.

As long as none of the objects have had any further changes, then whole changesets can be reverted with the offline editor JOSM and its Reverter plugin osm.wiki/JOSM/Plugins/Reverter. It's not something I've done in a while, but I'll give it a go if it's not something you want to tackle yourself - let me know!

Remember that the aerial imagery doesn't always line up with what's on the ground, and needs to be adjusted before you start aligning features to it. osm.wiki/Using_Imagery#iD

Pretty sure - why do you think it might not be? It only opened in this location November.

Hi, have you got a source for the bollard having a name? It seems an unusual thing!

Hi - I'm just looking at Iffley Lock. This was already in OSM (way/355542242) but now there's a new way with some additional tags (way/369908987). Did you mean to double this up, or is it an accident that needs correcting?

Cheers

If it's wrong, it probably wasn't intentional - as the changeset comment says I was correcting poor spelling and standardising tags to use established schemes. The problem with much of this "micromapping" is that it's very confusing when the next person comes to edit it - I don't really have a solution to this. Personally, I think it's a shame so much time/effort is being put into mapping interior levels and footpath areas when there are parts of the city without basic building outlines and address information, but family commitments mean I don't really have time to improve things myself with actually useful stuff at the moment.

The remains of Cowley Airfield is the park behind Herschel Crescent. Roads that were built on the airfield include:

Bartholomew Road (east of Church Cowley school)
Cholsey Close
Burgan Close
Lockheart Crescent
Barns Road (south of Boswell Road)
Kersington Crescent
Amory Close

The Southern part of Oxford Business park South and the land that Tesco/etc are on was also part of the airfield.

This is NOT a misconception that has led to the A420 being tagged this way, but the result of consensus being reached in the OSM community on the mailing lists. Much of the editing done in this area today needs to be wound back, and only redone once the changes have been approved by the community.

Please please engage with the other editors in your area before making changes like this.

I've never used planning documents for Openstreetmap because they all seem to be based on Ordnance Survey base maps. What's the licence situation here?

Hi - please don't use highway=towpath until you've got consensus on the wiki - it's going to break routing and mapping unless it's agreed upon.

What's with name=disabled_symbol - that (and nearby "roughlydrawn") is surely not actually the names of the feature is it?
