Joe,
I've been following your project with keen interest. This is really keen stuff.
Now, looking forward, two thoughts come to mind. One, how to adapt this to
lesson plans that can be easily adapted to classroom work. Two, how to apply
the same techniques, perhaps in real, or near real time,
EMike,
My code and processing scripts push through all of the data in a couple of
seconds. And that's processing ALL of it.
So it would be reasonably trivial to do all of this in realtime and have maps
with plots available with telemetry overlays / etc.
Now that I have all the hard work
This is excellent, Joe. Could this same technique be used for all the ISS
images as well?
It might be interesting to sequence all the ARISSat-1 images into a movie,
