Hi all,
I want to find endmembers from MODIS 36 bands and then perform linear
unmixing. Does any body have any idea whether it is possible in GRASS. How
do I perform unmxing. Is there any module avaliable.
Please reply, if anybody has worked on spectral unmixing in GRASS.
Hi Uttam,
yes, I was writing i.spec.unmix for my MSc. Two articles
are available:
