That would actually work out pretty good. Generally, the color maps are
generated from digital data to begin with, so if we could get that data
somewhere, we'd be well on the way.
My first post was tongue in cheek, of course - at least the section about
analyzing the graphics.
The second section is quite do-able, if the data is available and ... ahem
... I spend a few months teaching myself the software techniques/algorithms
for analyzing this stuff. :)
