Abstract

Abstract

This paper chose the Shuimo-Dahe area of Sichuan Wangcang as its research area, use ASTER image and in-situ measured spectra data by ASD FieldSpec3 as the research object, extract mineral endmember information according to rock spectral curve from field survey data and USGS spectral library, match the spectral curve of image pixel, combine ENVI4.4 software for automatic information extraction and man-computer interactive interpretation, to conduct lithology classification, based on GIS, it has an important application value for basic geological survey and mineral survey.
- spectral of minerals and rocks,
- ASTER,
- spectral angle mapper,
- matched filtering,
- lithological classification
