I have some field spectra that was collected with a ASD field spectrometer. I want to be able to use this data as endmembers for classifying a Hymap image. Problem is the Hymap is MNF-transformed, and the field spec is in reflectance. Its easy to transform an image, but I cant figure out how to MNF-transform a spectral library signature. Anybody have any ideas for this? - CHarlie F
