Abstract :
The ASTER sensor aboard the Terra platform has a capability of spectral measurement not only in visible and near infrared (VNIR) and shortwave infrared (SWIR) regions but also in thermal infrared (TIR) region with a spatial resolution adequate for geological applications. This paper proposes several spectral indices for rock type mapping using ASTER TIR data and applies them to a part of the Beishan Mountains in China. The result indicates that the indices are very useful in lithologic mapping
