Comment from JodaStephen
Hi, I noticed you have been aligning roads to Bing imagery. Are you aware of the new Cadastral boundaries, and that they are now being used as the golden definition of location? I've setup a new offset at Wimbledon Chase of (3.95,-2.22) for our area, and just wanted to make sure you knew about it.

Hey, I've been aligning to an offset of 4.1, -1.7 within this end of London, so we aren't far off.
I wasn't aware of the new boundaries though, do you have a link to a reference? I got my offset above from a mix of GPS and landmarks, so another source would be useful.
Unfortunately iD doesn't nag people to check offsets like JOSM does, so everyone else still seems to be mapping to the uncorrected imagery :(

The official-ness isn't perfectly explained, but this is the best link I have http://gis.19327.n8.nabble.com/OSMUK-response-to-Accuracy-of-cadastral-parcel-alignment-td5986988.html and there is this tweet about iD editor https://twitter.com/osmuk/status/1368983036751187972 . My offset is setup in https://wiki.openstreetmap.org/wiki/Imagery_Offset_Database under "Cadastral at Wiimbledon Chase". (Cadastral data is not 100% perfect, but I checked a few locations around Wimbledon Chase to ensure my choice was OK, and I always switch the layer on for each edit session.)

Wow that dataset is incredible, thanks for pointing it out.
Now if only I could convince everyone else to check offsets :/
