Thanks! Surveying on foot has been a good activity for me this year.

Corrected in changeset/98145409, thanks for the feedback. :)

It's entirely possible I messed it up; I did this edit on my phone while walking and might have forgotten to do an edit pass from a real computer afterwards. Thanks for the reminder, I'll get to it shortly!

I didn't add the abandoned:building=yes tag and I agree that it is not correctly used here. You can remove it with my blessing but that is not a change i am going to make.

disused:amenity=police is correctly used here because if you are looking for policing services you will find recent evidence of them but no activity.
