2015-8-6 For example, kaolinite is a common alteration product associated with both gold and copperdeposits. Hence, mapping concentrations of kaolinite using ASTER can indicate the presence ofthese ores. The ASTER data set contains visible, shortwave infrared and thermal bands. Theproper preprocessing and combination of these bands can produce relative mineral alterationdistributions

Combined phengite (yellow) and muscovite (blue) mineral maps draped over grey-scale 1 ASTER image. Individual index maps were clipped using a mean plus two standard deviation algorithm, then re-coloured.
ASTER imagery, as one of the multispectral sensors, can recognize mineral groups in the VNIR -SWIR range, and the data after processing allow potential mapping of minerals.
ASTER is the “zoom lens” for the other instruments. Terra is in a sun-synchronous orbit, 30 minutes behind Landsat ETM+; it crosses the equator at about 10:30 am local solar time. ASTER can acquire data over the entire globe with an average duty cycle of 8% per orbit. This

2010-7-13 minerals in Siyahrud area by different image processing methods on Aster imagery data such as false colore composite, band ratio methods and Crosta method.During the study,data analyses were carried out using ENVI4.2 software . At the end of processing data, validity of mentioned methods have been proved by field study.
2020-3-21 The ASTER color-ratio composite image 4/1, 3/1, 12/14 in RGB is introduced by Abdeen et al. to map exposed rocks in arid regions (Fig. 8). Kalinowski and Oliver used this ratio for mapping in the “ASTER Mineral Index Processing Manual.” The authors recommended it because of a high optimum index factor (OIF) and the presence of diagnostic
Remote sensing by satellite images is frequently used for geological mapping in desert or semiarid lands, and numerous excellent results have been obtained for sedimentary sequences using Landsat data (Sgavetti et al., 1995; Lang, 1999, and references therein).In contrast, satellite remote sensing is not considered to be readily applicable to the mapping of metamorphic and igneous sequences
2012-2-1 ASTER processing and calibration includes channel co-registration, geometric and radiometric correction, crosstalk correction and atmospheric correction, respectively, to retrieve pseudo reflectance data. A comprehensive overview of mineral indices that can be derived from ASTER data is the ‘ASTER Mineral Index Processing Manual
2016-10-14 Great Topic When you have ASTER Image lever 3b, you data is in Radiance you need to convert that data in Reflectance, with ENVI with FLASSH module you will use the make atmospheric corrections to change radiance values to reflectance to do spectral analyst, and another important thing is resampling your spectral library that you can use with ASTER.
2014-4-8 Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data covering the Jiafushaersu area in Xinjiang were used for mapping lithology and hydrothermal alteration. The study area situates at a potential mineralization zone in relation to small hypabyssal granodiorite or quartz monzonite intrusions along the margin of granitoid batholiths of Darbut foot wall.

ASTER Processing Methodology The following is a summary of the background and methodology involved in processing the multi-scene ASTER imagery. Detailed accounts will be provided in related publications. Physical model The ASTER processing methodology for the nine VNIR-SWIR bands follows that developed by Hewson et al (2005), Cudahy et al
2019-4-22 of all ASTER images are displayed in red (see Figure 2, below). Image Pre-Processing The ASTER imagery on the MapPlace have been orthorectified and atmospherically corrected before being placed on the site. Orthorectification was performed using the AsterDTM (SulSoft, 2005) add-on to the ENVI (RSI, 2005) image analysis program.
Many ore deposits are first detected in the field by the recognition of hydrothermally altered host rocks, and are typically zonally distributed. Ore deposits are often produced by fluid flow processes that alter the mineralogy and chemistry of the country rock. One of the main reason for extention using a multi-spectral and hyperspectral sensor is due to detect the optical characteristics of
2019-3-22 ASTER processing Pre-processing strategies and algorithms developed for handling the ASTER Level lb (radiance at sensor) data used for this study have been previously described by Hewson et al. (2005). In particular, data issues such as SWIR Crosstalk and
