ASTER, ALI and Hyperion sensors data for lithological

Some studies were carried out using EO1 data (ALI and Hyperion) for lithological mapping and ore mineral exploration. The capacity of VNIR and SWIR subsystems of Hyperion data for mineral mapping has been evaluated at Mountain Fitton, South Australia (Cudahy et al., 2001). The Hyperion derived mineral map indicated spatially coherent mineral
