I am thinking about getting a new Mac. Not any good reason for it though. I'll
try to wait it out for one of the new iBooks rumored for next spring. No new
PowerBook next month if new models come out. No. I said no! Stop thinking about

Planning battle tactics; for this reason, the intelligence press
reports, spy satellites have had 1-meter resolution for many years.
Finding an individual vehicle in a city might occasionally be possible
with 1-m images and might occasionally also be worth the money.
For small areas you have legitimate access to, it's probably cheaper
to go there with a digital camera and a GPS and take some snapshots
from ground level.  Aerial photos might be cheaper for large areas,
areas where you're not allowed --- or, perhaps, physically able --- to
go, and cases where you don't have time to send a ground guy around
the whole area.
