Hi, I'm currently looking into treatment of hyperspectral data in GRASS and have several questions:
1) I've seen that the addons i.spec.unmix and i.spec.sam have been ported to GRASS 7. Great job ! However, documentation is a bit sparse. One major question I have: does the signature matrix that is needed for these modules have to be projected to the same bands as are in the image it is compared to ? Or can these modules handle more generic signatures ? 2) Has anyone applied any other dimension reductions than PCA on hyperspectral data in GRASS ? 3) Has anyone tried to implement any of the automatic endmember targeting algorithms in GRASS ?
