Thanks - makes sense. I've changed it to "farm_auxiliary".

EV1 should be OK here now: http://ra.osmsurround.org/analyzeRelation?relationId=9540148 .
Also EV2 http://ra.osmsurround.org/analyzeRelation?relationId=5479822 .

Thanks for updating this to say that the change was based on local knowledge.

Thanks for confirming local knowledge here in the update to way/507631409/history .
(to anyone else spotting this - it's clearly visible on OSM-compatible imagery too).
Local knowledge I presume also applies to way/498577935/history (which is in the same area, and from which another mapper has removed the Google tag)

Reverted in changeset/165369722 and redacted

Thanks!

There are a few options - one is to keep them as a multipolygon but to remove the "building" tag from relation/13505281/history and add "building=yes" to way/152963307 and "building=roof" to way/222122213 . Another option is to draw the larger perimeter of the fuel station area and move the tags to that (without a building tag) or to a node (again without a building tag)

I'd be really helpful to be a bit more descriptive in changeset comments - "tweak areas" is doing a lot of heavy lifting here as this is actually a revert using JOSM's revert plugin...

Thanks - done in changeset/165235237

Hello,
I'm a bit confused by the change here. Previously way/881142231/history was an area runway and it didn't have a linear component. The MR challenge said to add the linear runway and change the area to area:aeroway=runway, but you didn't do that - you removed the area tag, which meant that it's possible to misinterpret the runway as a linear circle.
Am I missing something here, or does the data need fixing here?
Best Regards,
Andy

Thanks - obvious really!

Hello,
I think that something gone a bit wrong here.
After this changeset, way/1287508458/history is aligned with the area of the agricultural building visible on aerial imagery, but the building type is "house (site of)" and the name seems a bit odd for an agricultural building.
If you look at https://overpass-api.de/achavi/?changeset=158935998 and zoom in you can see what happened - that name and building type corresponds to something that was here a long time ago ("ty'n y nant" - "the house in the stream"). That was added in changeset/151963821#map=15/52.39429/-3.92576 . I've no idea what the source was since that changeset doesn't say, but whatever it is that name and building type probably belongs on https://www.openhistoricalmap.org rather than here.
I'll update that (and the others).
Any questions about how to spot these, please get in touch!
Best Regards,
Andy

Hello,
Should way/1329335285 perhaps be "operator=SSE" rather than building=sse"?
Best Regards,

Hello,
What is a "building=barb"?
way/644918873#map=20/54.1568336/-2.1386904&layers=H
Cheers,
Andy

I've set it back to yes :)

You didn't add it originally, but have you any idea what sort of building way/51583113 is? It does match OS OpenData but doesn't match Bing imagery, suggesting that something might have been rebuilt in its place?

Hello, and welcome to OpenStreetMap!
You've set way/1272898465/history to "building=closed". If it's still a pub building but the pub is closed, more appropriate would be "building=pub" and "disused:amenity=pub".
Best Regards,
Andy
PS: Any other questions, please don't hesitate to ask!

I'm guessing that "building=yesrunning_or_walking_while_listening_to_some_music_or_a_podcast_can_get_you_into_a_great_rhythm_-_please_just_be_careful_that_it_doesn’t_end_up_distracting_you._when_crossing_the_road,_temporarily_remove_your_headphones_and_avoid_interacting_with_your_ph" was an accident here?
I've changed that in changeset/165089530

Thanks!

Oops - I think that this might have created a gap in the Thames Down Link path - you can see that at relation/115934#map=20/51.2696199/-0.3117511 .
Are you OK to fill in the gap, or would you need any pointers to help doing that?
Cheers,
Andy
