Abstract.
The study area is located in the district of Yura, Arequipa Region, Peru.
The study aims to show the
use of Advanced Spaceborne Thermal Emission and Reflectance (ASTER) data, the application of spectral
analysis for mineral mapping (alunite, kaolinite, illite, smectite) and the results comparison between Spectral
Angle Mapper (SAM) and Matched Filtering (MF) techniques.
This work describes a method for mapping using ASTER data, initiating with the pre-processing of ASTER
image (resulting reflectance and apparent reflectance); after the spectral signatures of the image can be
compared with the signature from USGS database; then the processing of the data includes the nads combination,
ratio and indexes used to get th
