Thanks Nick, that was a helpful kickstart.  The one query I still have 
is are all the blue structures tents? As you say, most have appeared 
where there was once a building and in some cases they are alongside.  
I've not tagged any as tents as most seem to be in place of a building 
or as well as a building so I wonder wether they are "tarps" that have 
been draped over ruins or damage?   So I've simply marked the building 
as damaged.
