Hi Bob and all,
Google Earth uses the same composite images as does Google Maps on line.
Being software GE has it's own viewer to manipulate the image it
downloads from GM. If you use an external viewer to manipulate an image
captured from GM (such as IRFanview) you'll notice the same blurring. For
that matter the same will happen if you enlarge any digital image, it's
called "pixelization" to use a television broacast term rather
inappropriately but as a point of reference.
When you "blow up" any image either optically or digitally (comparing
film grain to pixels here) you're not adding detail to the image, that
requires more pixels and they don't come out of thin air. What you're
doing is enlarging the pixels to the point where they become visible in
the image. Blow it up enough and you see ragged borders with squared
bits. These are the edges of the pixels, pixels are square. Remember the
old video arcade games with those blocky looking robots and space aliens?

You can't do a whole heck of a lot with 4 bits so the pixels were huge.
Oh here we go again! Oh well, another copy and paste job in the offing. Anyway you get the idea, you can only do so much zooming in before the image looks out of focus but it's really those big pixels in your eyes. Bob, have you seen the blue kangaroo on your roof yet? Geoff rather goofed, roos old enough to hop that high are generally bigger, that one's a baby. (;->)
