@bluestarfish I'll see if I can join, and maybe get help to map buildings in Chiswick as my whole neighbourhood is just *empty*.

And I'm not super comfortable with the satellite imagery as Bing's seems to be quite outdated :-/

@Girgias I would suggest not to use Bing for adding buildings.

Instead, I use the "NLS - OS 1:1,250/1:2,500 National Grid Maps, 1947-63 - TQ" layer as reference.

I draw from that, and then verify it's still up-to-date by walking around and looking what changed. Having an existing reference makes it a lot easier, and on top of that you get (some) address information too.

To do terraced buildings (like south of Chiswick High Street), I created the Uberterracer plugin: https://josm.openstreetmap.de/wiki/Plugins

@derickr did you do Turnham Green Terrace? Someone mapped that with building parts and separate floor mapping, which I might have botched once by using an editor that didn't make that complexity obvious.

@milh0use I see @Girgias just updated https://www.openstreetmap.org/way/209434700 — and it indeed looks wrong now (not due to her change). But it was Paul, not me, who added it in the first place (but at a mapping party I was at too). Let me see if I can fix it.

@milh0use @Girgias I've added a building tag, but I see that almost all the bicycle parking stands on that street are doubled (some added by you, and some by @Girgias too).

@derickr @milh0use there are a *lot* of bicycle stands on Turnham Green Terrace
Show threadDerick RethansMar 4
@Girgias @milh0use I know, but nearly all are duplicated. Nodes nearly on top of each other.

@derickr I wonder if that's my fault and I added them thinking they were missing when I just need to refresh the EveryDoor cache?

@milh0use It's possible. I didn't see it which ones were first.
