Imaging spectroscopy retrieval

Base sensing method for spaceborne imaging spectrometers: acquires per-pixel spectral fingerprints across contiguous VNIR-SWIR bands, producing a spectral cube from which material composition, vegetation biochemistry, or land-cover classes are retrieved. Spectral-library-matching and supervised-tree-ensemble-classification build on this base retrieval.

Imaging spectrometers (EnMAP, HyperScout-H, EMIT, DESIS, PRISMA) sample contiguous VNIR-SWIR spectral ranges at high spectral resolution, yielding a per-pixel spectrum. The base retrieval step produces atmospherically corrected surface reflectance cubes. Analysis methods (spectral-library-matching, supervised-tree-ensemble-classification, spectral-unmixing) apply on top of this cube product. Wikipedia: Hyperspectral imaging
