ASTER Spectral Analisys with ENVI

[zabdi3l]

Hi

I tried to made spectral analisys to ASTER image.

I have mi 3A level ASTER image in .hdf format. I use ENVI

With ENVI I open the .hdf and ENVI make auto-correct for ASTER Radiance

I re-size the SWIR band to 15m pixel

I made layer stacking to VNIR_SWIR bands and convert to .BIL

With the VNIR_SWIR .BIL image a made a correct atmospheric correction with FLAASH to convert radiance to reflectance

I resample te USGS spectral library to ASTER

I use the mapping method Spectral angled mapper

I change the Y scale from the spectral library to 10000 to si the values 10*4 to have the same values from my image Z values for spectrum

I select for example from the spectral library Kaoli to use in spectral angle mapper and in Maximun angle (radiand) I change to 1 because in .100 this dont show me nothign in SAM classification

But the problem is for the al spectral I made this show me the same pixels
