But I notice two queries for maps.

WARNING! Satellite images are not maps!
If your intent is only to have a cute bit maps for workstations,
no problem.  Buy to your hearts contents.  BUT,....
Raw images are deficient from maps on several counts.  The process
is worth several PhD theses on geographic information systems/image
processing, and other aspects of graphics, but raw images should NEVER
be used as maps requiring ANY accuracy, subject to knowing the processes
which created these images.  You might hear of things called
"ortho-photographs" these are not maps and nor are they raw images.
They are better, but should NOT be used as maps either.

Another gross generalization from
