This is really informative and makes perfect sense..... makes my life a
lot harder, but perfect sense
If I Could i ask a follow on question to this,
What is the recommended processing paradigm for slightly
off-nadir imagery where their is a need for a full [3x3] matrix mapping
to take it to a consistent projection? ie the images have at a minimum
perspective effects.
the reason i ask, is i have a significant image pile that needs
this re-projection to remove camera lens + perspective effects , to map
it to a consistent conformal projection? Can i do this with gdal_warp?
or do i need to code this up, and then go from their once their is just
a rotation / scale left.
Many thanks
Joe

The basic point is that this process is starting from a belief that the
imagery is consistent and needs only translation, scaling, and rotation.
That's not quite true, as a general matrix multiply is looser than a
rotation and scale, having 4 variables vs 2.
