Characteristics of Landsat and ASTER

Methodology • Band combination and Band ratio method • Multi spectral signature by using multispectrum software for mineral composition, and rock. • Compare with True color and False color composite

Procedure

Spectral signature analysis • channels 1, 2 and 3 are seen on the x-axis • The pixel values are seen on the y-axis. • average pixel values • Cluster…water, Mineral, Rock unit….
