I was  playing around with Google Earth yesterday, tracing down the line 
of the  Farmer's Bridge flight on the Birmingham & Fazeley canal.  There  
is something peculiar about the BT tower - it seems to have fallen over.  :-)





The lower level photos are actually taken from a plane that flies a regular  
pattern back and forth across the target area. I remember seeing one doing 
this  across the centre of Southend. Having done a (fairly short) run 
east-west, 
it  would turn and fly back along a parallel path. The resulting pictures are  
stitched together to produce the database, and it doesn't matter which 
version  of the viewer you use.
 
If you close in on any building and turn the image round, there will always  
be a 'natural' view of it where the image is less distorted. On a house, for  
example, you will always see one wall where you can see all of it and one 
where  the roof appears to overhang the wall so much that it is hidden. The 
taller 
the  building, the more the apparent lean.
