I work in the borehole instrumentation industry, and lots of our customers get hyperspectral data from core. I'm working on a new data delivery and management platform, and I've made sure our data structures can handle hyperspectral images. Multidimensional arrays are front and centre. I too think of spectral images as "cubes".

One thing that stems from this is the question of how you visualise it. False colour mapping?

I found that people think that whatever you are doing must be extremely cool if you display it with the 3rd dimension being time. So create a video of each frame of the hyperspectral image and it shifts from one frame to another. Idk if it is super useful but if you put the video on a powerpoint it gets lots of excitement

Wikipedia has an article on hyperspectral imaging that also talks about how these images are acquired.
