[Talk-GB] High quality NLS imagery of buildings and HOUSENUMBERS (!) available in London (and Scotland). Create a tasking manger to add this?

This is why I think that a tasking manager is good. Firstly, it is not exactly "wholesale" in the sense that a lot of data with little checking. Every square is mapped and then validated as well. 

Secondly, this is why it is imperative to check if the buildings still exist on Bing. If they do, almost certainly the housenumbers haven't changed. (As mentioned by spiregrain). If the buildings have changed, then you can mark a square as "bad imagery", making the tasking manager even more useful (so that you can discern where the imagery is accurate and where it isn't).

It's out of copyright, so there aren't any licensing issues in deriving data from it.I would, though, be a little reluctant to use it as a basis for wholesale numbering without any supporting local knowledge or survey. House numbers can, and sometimes do, change, particularly when streets are renamed or rebuilt. So you can't be 100% certain that a house number in the 1950s is the same number it is now, even if the building is still the same.
