The used scene of Hyperion hyperspectral remote sensing image have contiguous 242 narrow bands in the range of $0.4-2.5 \mu \mathrm{m}$ with capability of spatial and spectral resolutions such as $30 \mathrm{~m}$ and $10 \mathrm{~nm}$, respectively, with narrow swath coverage of $7.5 \times 100 \mathrm{~km}$ including high radiometric accuracy of 12 bit quantization $[1,5,11$, $1214]$

The AVIRIS-NG hyperspectral remote sensing data have 425 narrow contiguous bands in spectral region of VNIR and SWIR ranging from $0.38$ to $2.51 \mu \mathrm{m}$ of electromagnetic spectrum. The spatial and spectral resolutions are $8.1 \mathrm{~m}$ and $5 \mathrm{~nm}$, respectively $[2,6,9,16]$. The adopted methodology for mineral identification is divided into three parts such as pre-image processing, extraction of mineral spectra, and validation. The stage of prefield-image processing contains de-striping, bad band removal, and atmospheric correction. The second stage related to extraction of mineral spectra through image. Third stage involves in matching of image-extracted spectra and measured spectra of minerals through USGS mineral library spectra and with field samples spectra. There are 155 bands and 390 bands were found suitable for mineral identification and extraction of spectra by Hyperion and AVIRIS-NG hyperspectral image, respectively (Fig. 2).

The comparative analysis of extracted spectra of talc mineral by Hyperion hyperspectral remote sensing image of Chabhadiya area of Jahajpur, Bhilwara, Rajasthan shows diagnostic absorption features at $2.31 \mu \mathrm{m}$ due to $\mathrm{Mg}-\mathrm{OH}[3,5,12,21]$. Absorptions present at $1.4$ and $1.9 \mu \mathrm{m}$ due to $\mathrm{OH}$ and $\mathrm{HOH}$ overtones. There is some minor absorption also presents between $2.0$ and $2.2 \mu \mathrm{m}$. In spectral range of $0.4-2.5 \mu \mathrm{m}$, some major absorption such as at $0.45 \mu \mathrm{m}$ due to $\mathrm{Fe}^{3+}$ and at $0.9 \mu \mathrm{m}, 1.1 \mu \mathrm{m}$ due to $\mathrm{O}{2}$ and $\mathrm{H}{2} \mathrm{O}$ also identified in VNIR region of EMR. The Hyperion image spectra showing deep absorption at $0.85-0.95 \mu \mathrm{m}$ which is indication of the presence of hematite [24] and showing normal absorption at near $0.456 \mu \mathrm{m}$ [10]. The spectral analysis of AVIRIS-NG extracted talc mineral spectra shows diagnostic absorption at $2.31 \mu \mathrm{m}$ with doublet $2.29 \mu \mathrm{m}$ due to $\mathrm{Mg}-\mathrm{OH}$, and $1.4$ and $1.9$ due to overtones of $\mathrm{OH}$ and $\mathrm{HOH}$. At near $1.4-1.5 \mu \mathrm{m}$ and $2.0 \mu \mathrm{m}$ shows maximum variation in absorption due to $\mathrm{O}{2}$ and $\mathrm{CO}{2}$ which is not present in the Hyperion image. Absorption at $0.47$ and $0.6 \mu \mathrm{m}$ indicating the presence of $\mathrm{Fe}^{3+}$, (Hematite) and lesser deep absorption at $0.9 \mu \mathrm{m}$ which is unavailable in Hyperion image. Various minor absorptions are also present minutely compared to minor absorption features of Hyperion image. The shape and reflectance value are also differentiating the characteristics and properties of both spectra. The subtle changes and subtle variation in shape, reflectance, and absorption can be observed very minutely in AVIRIS-NG than the Hyperion image. The spectroscopic spectra of talc field samples also validating the potential and capability of identification of talc and hematite with absorption at $2.31 \mu \mathrm{m}$ with doublet at $2.28 \mu \mathrm{m}$ with overtones of $\mathrm{OH}$ and $\mathrm{HOH}$ at $1.4$ and $1.9 \mu \mathrm{m}$ and $\mathrm{Fe}^{3+}$ presence identified at absorptions at near $0.56$ and $0.9 \mu \mathrm{m}$, respectively. The shape, absorption, reflectance, and depth of image spectra of Hyperion and AVIRIS-NG in correlation of spectroscopic result of field sample spectra including comparison with USGS talc minerals spectra shows the most accurate and acute capability and performance of AVIRIS-NG hyperspectral images. The USGS talc mineral library spectra show complete matching of identified and measured spectra of talc through Hyperion, AVIRIS-NG, and spectroscopic field sample spectra (Fig. 3).
