Are you sure that putting street names from findmystreet complies with that site's licence conditions?

Fair enough.
My recollection is that for a lot of estates the name tag was applied to the residential area and these didn't render very well on the map, so I copied the name tag onto a point within the area. However the area of "Woughton Park" doesn't have a name tag, maybe someone deleted it.

I've taken another look at this area. It's now paved, with seating and some beds of shrubs. Hardly unique, but I can't quickly find anything nearby mapped to this level of detail to compare.

It's a square-shaped area of gravel at the junction of the paths. I think there may be an artwork of some kind at the centre but I don't recall the details. If there is a better way to tag it then so be it.

I drove past the site of this 'new development' this morning, and there is nothing but a muddy field with a couple of diggers churning it up. As I understand it we are mapping how things are, not how they might be in the future. Also I'm not sure where the information came from; there is nothing on Bing or OS OpenData - anything else is likely to be copyright. Can I suggest removing this until the houses and roads are actually built and then surveying by GPS?
PS I'm just a mapper too!

I'll do some more GPS surveying over the weekend to plot in the cinema and the other car parks. But next time I'll do it on foot - the place is too dangerous to cycle around with cars pulling out of parking spaces without looking...
