Abstract :
The POSAM method identifies each pixel in the hyperspectral data to create an alteration mineral map. An IDL program for "ENVI" was developed. Data processing using the POSAM method was conducted on AVIRIS and Hyperion data. The mineral map created from the AVIRIS data showed better results compared to the general processing method proven by ground truth survey, but only few pixels were identified from the Hyperion data.
