Thanks; fixed. It's the school playground. I've had a bunch of things duplicated from JOSM edits somehow.

I was about to say that's what's on their schematic, but the web version says Main Track, so I probably mis-remembered. Or do you mean it shouldn't be tagged with the name.

Thanks; I'll fix them. JOSM keeps failing to catch things like that which should have been changed from the imported data. How did you find them?

Thanks. I wonder why I didn't see the original, but I don't understand the iD search. I'd better look at the others.

The source should have been OS_OpenData_OpenMapLocal, not VectorMap. It wasn't proprietary data.

I'm sure the buildings need refining. The OS outlines suggest they've been derived automatically from imagery, and less accurately than osmai. It's a basis, anyhow. (I don't know much of Cleeve.)

The house postcode looks as if it should be GL54 1JQ, not 1JT (e.g. on Zoopla).

I'd forgotten to worry about assorted changes I've seen sourced from the University of Manchester campus map, with a view to at least trying to get permission to use that, if not Estates data direct. However, I notice you've used it in this changeset, and doubtless would be careful. Is there some sort of copyright clearance for it, or other legal justification?

Do you understand the designation of Wyman's Brook east of Pittville lake, specifically south of Bouncer's Lane cemetery?
Historical and current OS labels the currently-unmapped stretch of stream by Slad Way, and nothing else I can see. The OSM source is given as NPE, but I don't see it named anywhere on NPE, and I don't know what else might be definitive and accessible.
I should inspect the Oakley estate construction area soon, but a visit presumably wouldn't help with this.

Oh, yes, ta. I keep realizing I've been doing things sub-optimally, but I should have found the relevant part of the wiki.

Updated, ta.
