Hi,

Thanks for your comment. I've realised a few things from this:
1. I had only looked on Vespucchi and saw there was no aerial imagery of the houses, hence the number of notes. 
I didn't want to walk and stop for two minutes outside every single house (and drawing unnecessary attention to myself) to add a building node from there. Adding a note from SC while gpx tracking was quicker

However, I've since seen on iD that Maxar Premium Imagery has quite up to date imagery, only missing one or two since built houses I think. I've added all the aerial imagery houses and will do something like this in the future prior to going out.
