Evaluating Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data for alteration zone enhancement in a semi‐arid area, northern Shahr‐e‐Babak, SE Iran

Identification of hydrothermal alteration minerals for exploring of porphyry copper deposit using ASTER data, SE Iran

“…PCA is a well-known Hubner, 1969b;Mars and Rowan, 2006). method for lithological and alteration mapping in metalogenic provinces (Crosta et al, 2003;Ranjbar et al, 2004;Kargi, 2007;Massironi et al, 2008;Moore et al, 2008;Tangestani et al, 2008;Amer et al, 2010). Standard PCA transformation has applied to the two full ASTER scenes of the Sarcheshmeh and Meiduk regions.…”

Digital Mapping of Soil Properties Using Multivariate Statistical Analysis and ASTER Data in an Arid Region

“…The results showed high correspondence between the measured spectra and those extracted from AST L1B calibrated and atmospherically corrected dataset. Due to inconsistency in Band 9 of the AST07 product, the image spectra could be unreliable to estimate and map surface soil properties with reasonable accuracy [82,83]. On the other hand, AST L1B atmospherically corrected with ATCOR software was successfully used in various mapping applications [82,84,85]; therefore, the atmospherically corrected Level 1B dataset was applied also in this study to model selected soil properties.…”

Iron ore prospection East Aswan, Egypt, using remote sensing techniques

“…(2) Principal Component Analyses (PCAs) to produce uncorrelated output bands, segregate the noise components and to reduce the dimensionality of data sets in the way of showing iron ore concentrations, (3) band ratio methods have been used for exploring the iron ore rich localities separating them from the host rocks and creating an iron index map, (Crosta and Filho, 2003;Kargi, 2007;Massironi et al, 2008;Moore et al, 2008;Tangestani et al, 2008;Amer and Kusky, 2010;Pour and Hashim, 2011, 2012a,b, 2013Hashim et al, 2011). Several band ratios of ETM + and Landsat 8 have been experimented for finding the efficient ones in iron exploration.…”
