Have you guys looked at NASA's world Wind?

It's also alot of fun to play with.

Thus spake Jonathan Rickman (jrickman at gmail.com):

&gt; I don't know the answers to your specific questions, but I can
&gt; enlighten you as to the source of most of the detailed photos. The
&gt; detailed photos are not satelite imagery. At some point as you zoom in
&gt; the photos transition to aerial photos taken some time in 2004. If you
&gt; want to see the limits of satalite imagery (at least commercial) have
&gt; a look at the overheads from a non metro area. You should check out
&gt; the keyhole app that all of this is derived from. It reveals the
&gt; source of the imagery. It's also more fun to play with. Windows only
&gt; though. :-(

&gt; &gt; While gmap'ing over the ATL airport yesterday I noticed that you can see
&gt; &gt; 3 planes in position over runway 8R (northside takeoff).  If you click
&gt; &gt; the URL below you will see one plane that has just departed.  If you
&gt; &gt; navigate to the left you will see one plane that has just left the
&gt; &gt; concrete, and move further to the left you will see one plane beginning
&gt; &gt; it's take-off roll.  Clearly this would be an FAA violation.  So, since
&gt; &gt; all three planes look identical in the pictures, it is safe to assume
&gt; &gt; they are all the same plane.
&gt; &gt; 
&gt; &gt; So a few questions to ponder:
&gt; &gt; 
&gt; &gt;  -Is it safe to assume the camera is moving west to east?
&gt; &gt; 
&gt; &gt;  -Take off speed would be about 150 mph (Sega Airlines ;-) so
&gt; &gt;     how fast is the camera moving?
&gt; &gt; 
&gt; &gt; -The satellite image captures frames as it passes over earth,
&gt; &gt;     why does it not show 2 slow moving planes/objects on top of
&gt; &gt;     each other?  (see cars/trucks on nearby expressways)
