Why hyperspectral imagery needs atmospheric correction to convert L1B top-of-atmosphere radiance to L2A surface reflectance, and tools (ATCOR, ENVI QUAC, ACOLITE, Py6S) for Wyvern data.

How spectral signatures identify materials in hyperspectral imagery, plus mixed pixels, endmember extraction (spectral unmixing), and pixel classification techniques.

Earth observation processing levels (L0–L4) explained, plus the details of Wyvern's L1B top-of-atmosphere radiance product, including projection, units, and delivery format.
