The difference between L1B top-of-atmosphere radiance and L2A surface reflectance for Wyvern data, what Wyvern's L2A product corrects, and the tools to use if you are correcting L1B yourself.

How spectral signatures identify materials in hyperspectral imagery, why mixed pixels complicate that, and the main methods for handling them: endmember extraction, spectral unmixing, and spectral matching.

Earth observation processing levels (L0–L4) explained, plus the details of Wyvern's two delivered products: L1B top-of-atmosphere radiance and L2A surface reflectance, with their projections, units, data types, and NoData values.
