Lithological and alteration mineral mapping in poorly exposed lithologies using Landsat-8 and ASTER satellite data: North-eastern Graham Land, Antarctic Peninsula
TL;DR: In this article, a two-stage methodology was adopted to distinguish pixel and sub-pixel targets in the satellite images, where the first stage used Continuum Removal (CR) spectral mapping tool and Independent Components Analysis (ICA) technique were applied to Landsat-8 and ASTER spectral bands to map the pixels related to poorly exposed lithological units.

Hydrothermal alteration mapping from Landsat-8 data, Sar Cheshmeh copper mining district, south-eastern Islamic Republic of Iran
TL;DR: In this article, the applicability of data from the recently launched Landsat-8 for mapping hydrothermal alteration areas and lithological units associated with porphyry copper exploration in arid and semi-arid regions was studied.
Journal ArticleDOI
Identifying areas of high economic-potential copper mineralization using aster data in the urumieh-dokhtar volcanic belt, Iran
TL;DR: In this article, spectral image processing methods were applied to ASTER data for mapping hydrothermal alteration zones associated with porphyry copper mineralization and related host rock, including phyllic, argillic and propylitic mineral assemblages.

A transformation for ordering multispectral data in terms of image quality with implications for noise removal
TL;DR: In this paper, a transformation known as the maximum noise fraction (MNF) transformation is presented, which always produces new components ordered by image quality, and it can be shown that this transformation is equivalent to principal components transformations when the noise variance is the same in all bands and that it reduces to a multiple linear regression when noise is in one band only.

Towards a paleogeography and tectonic evolution of Iran
TL;DR: In this paper, maps of the paleography of Iran are presented to summarize and review the geological evolution of the Iranian region since late Precambrian time on the basis of the data presented in this way reconstructions of the region have been prepared that take account of the known major movements of continental masses.

Spectral signatures of particulate minerals in the visible and near infrared
TL;DR: The utility of multispectral remote sensing techniques for discriminating among materials is based on the differences that exist among their spectral properties as distinct from spectral variations that occur as a consequence of target condition and environmental factors, intrinsic spectral features that appear in the form of bands and slopes in the visible and near infrared (325 to 25 μm) bidirectional reflection spectra of minerals as mentioned in this paper.
Mapping target signatures via partial unmixing of AVIRIS data
TL;DR: In this article, the authors proposed a method to map apparent target abundances in the presence of an arbitrary and unknown spectrally mixed background, which allows the target materials to be present in abundances that drive significant portions of scene covariance.
