Cuprite Synthetic Dataset

The Cuprite HSI dataset covers a region around Las Vegas, Nevada, USA, and comprises a 512×614, 188-channel HSI. The area under observation contains 12 minerals (or, for our purposes, endmembers): Alunite, Andradite, Buddingtonite, Dumortierite, Kaolinite1, Kaolinite2, Muscovite, Montmorillonite, Nontronite, Pyrope, Sphene, and Chalcedony. The Cuprite dataset lacks pixel-level abundance information that the proposed model needs for training. We explored transfer learning to deal with this issue. We constructed a Cuprite Synthetic dataset that uses the same materials as those found in the Cuprite dataset. The spectra for these materials were taken from the USGS spectral library.
