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. DaveD [Non-text portions of this message have been removed]
