Abstract

Abstract NASA’S EO-1 Hyperion sensors launched in November 2000. It provides good opportunity to evaluate the spaceborne hyperspectral capabilities. Hyperion sensors cover 0.4 to 2.5μm range with 242 spectral bands at approximately 10nm spectral resolution and 30m spatial resolution from 705km orbit. The enhanced information contains sensors which provides, hyperspectral analysis methods, namely Minimum Noise Fraction- transformation (MNF) for data quality assessment and noise reduction as well as Spectral Angle Mapper (SAM) for classification of Mineral potential zones. The Classification results show the detailed information that can be extracted from the source of information. The analysis reveals that Hyperion scene is strongly affected by system induced radiometric interferences. As a result considerable amount of bands are to be discarded to allow satisfying results.
