The military already have these spy satellites; they are basically
|
|
Hubble pointed the other way, so I doubt they will be a big enough
|
|
customer of this service to justify a next-generation wireless
|
|
network rollout for the rest of us.

My car is only just over 1.5 meters across and maybe 3 meters long, so
|
|
that means roughly six pixels total surface area. You might find a
|
|
16-wheeler this way, but how often do people misplace a 16-wheeler
|
|
such that it is _that_ important to get old images of the terrain?
|
|
Since they can't send up aircraft to update images in realtime every
|
|
time, how is this different from just releasing the map on DVDs? Why
|
|
wireless?
|
|
|
|
I thought of the common problem of lost prize cattle, but there again,
|
|
will there really be business-case for creating a hi-res map of
|
|
wyoming on the fly instead of just doing what they do now and hiring a
|
|
helicopter for a few hours?

I can see lower-res being useful for Geologists, but considering their
|
|
points of interest change only a few times every few million years,
|
|
there's not much need to be wireless based on up-to-the-minute data.
|
|
I expect most geologists travel with a laptop perfectly capable of DVD
|
|
playback, and I also expect the most interesting geology is in regions
|
|
where the wireless ain't going to go ;)
|
|
|
|
I don't mean to nit-pick, it's just that I'm curious as to (a) the
|
|
need for this product that justifies the extreme cost and (b) how we'd
|
|
justify the ubiquitous next-generation wireless network that this
|
|
product postulates when we /still/ can't find the killer app for 3G.
