Agree, but if in the close surroundings I see some elements (trees) with
projected shadow, I assume I have a collapsed building. I don't know how
tall trees are, just approximate 5-10meters for a 5-10meters canopy, which
IMO can be compared to 3-5meter height of a rural building.
Anyway I make just assumpions. Of course, if you are exeprienced in
photogrammetry I'll take care of your suggestions.
