Comparison of AVIRIS and Hyperion for Hyperspectral Mineral Mapping
1.0 Introduction The 0.4 to 2.5 μm spectral range provides abundant information about many important Earth-surface minerals (Clark et al., 1990). In particular, the 2.0 to 2.5 μm spectral range covers spectral features of hydroxyl-bearing minerals, sulfates, and carbonates common to many geologic units and hydrothermal alteration assemblages. Imaging Spectrometers, or “Hyperspectral” sensors pr...
متن کاملBand Clustering for the Lossless Compression of AVIRIS Hyperspectral Images
Hyperspectral images can be efficiently compressed through a linear predictive model, as for example the one used in the SLSQ algorithm. In this paper we exploit this predictive model on the AVIRIS images by individuating, through an off-line approach, a common subset of bands, which are not spectrally related with any other bands. These bands are not useful as prediction reference for the SLSQ...
متن کاملMineral Mapping with AVIRIS and EO-1 Hyperion
1.0 Introduction Imaging Spectrometry data or Hyperspectral Imagery (HSI) acquired using airborne systems have been used in the geologic community since the early 1980’s and represent a mature technology (Goetz et al., 1985; Kruse et al., 1999). The solar spectral range, 0.4 to 2.5 μm, provides abundant information about many important Earth-surface minerals (Clark et al., 1990). In particular,...
متن کاملPotential of Resolution-Enhanced Hyperspectral Data for Mineral Mapping Using Simulated EnMAP and Sentinel-2 Images
Spaceborne hyperspectral images are useful for large scale mineral mapping. Acquired at a ground sampling distance (GSD) of 30 m, the Environmental Mapping and Analysis Program (EnMAP) will be capable of putting many issues related to environment monitoring and resource exploration in perspective with measurements in the spectral range between 420 and 2450 nm. However, a higher spatial resoluti...
