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

[Ken Kilfedder]

I've made extensive use of these tiles for numbering tasks in London E15 and E7.  But you are right that more up to date material is needed.  Bing gives me the more modern building outlines,  and I then do some spot checks of the NLS-sourced housenumbers when I survey the newer buildings.

But I don't recall any instances where NLS was 'wrong' for buildings that are still standing.  Maybe the odd 45 vs 45a etc.
