Tutorial: Hyperspectral Signatures and Spectral Resolution
View AVIRIS Image and Spectra
AVIRIS data have approximately 10 nm spectral resolution and 20 m spatial resolution. The AVIRIS data used
in this exercise were acquired during July 1995 as part of an AVIRIS Group Shoot (Kruse and Huntington,
1996). The following plot shows the ROI mean spectra for kaolinite, alunite, and buddingtonite. Compare these
to the library spectra and note the high quality and nearly identical signatures.
