I'm not sure.  You could well be right about 'tarps', & I think in some 
places materials such as corrugated iron sheets have been reused. What 
was once extensive tree cover obscuring buildings is now fairly open 
ground, so in some cases the outline has changed purely because we can 
now see the whole structure.
