The study area is located in Jabal-Barez Ranges, southeastern part of Kerman Copper Belt (KCB), where the porphyry copper mineralization such as Kerver occurs. This article deals with the enhancement of hydrothermal alteration minerals for exploration of porphyry Cu mineralization, and differentiates intense hydrothermal alteration zones from those with low intensity. Shortwave Infrared (SWIR) ...

In this study, we comparison of NDVI of ground measurement, atmospheric corrected ASTER LIB data and ASTER surface reflectance product (AST07) data to evaluate the accuracy of the ATCOR software atmospheric correction of Terra/ASTER data (Jun 30, 2002), using ground radiometric measurement data (ASD's FieldSpec® Pro). Our research selected the study area Sarobetsu Marsh located in coastal area ...

To determine suitable indices for vegetation cover and production assessment based on remote sensing data, simultaneous digital data with field data belonged to summer rangeland of southern part of Isfahan province were analyzed. During 2 years of monitoring, annuals, grasses, forbs and shrubs vegetation cover and total production data from sixty 1 square meter plots in each site were collected...

The RST (Robust Satellite Techniques) approach is a multi-temporal scheme of satellite data analysis widely used to investigate and monitor thermal volcanic activity from space through high temporal resolution sensors such as the Moderate Resolution Imaging Spectroradiometer (MODIS), Spinning Enhanced Visible Infrared Imager (SEVIRI). In this work, we present results preliminary algorithm imple...

The detection of geothermal anomalies using Thermal Infrared (TIR) remote sensing data is challenging because how sensor specifications (such as the infrared wavelength used for measurement, spectral dependence emissivity, angle at which measurement made, state surface and height above surface) physical parameters solar radiation, topography, albedo, soil compaction coherence rocks) affect Land...

This paper presents a new remotely sensed solution for monitoring the recovery of a large disaster-affected area. It exploits the powerful data grid and computing grid technologies developed on GEO (Global Earth Observation) Grid system. Accessing the ASTER portal site of GEO Grid, all the necessary ASTER multi-spectral images and on-demand ASTER digital elevation model (DEM) are easily and qui...

The Global Digital Elevation Model produced from stereo images of Advanced Spaceborne Thermal Emission and Reflection Radiometer data (ASTER GDEM) covers land surfaces between latitudes of 83°N and 83°S. The Phased Array type L-band Synthetic Aperture Radar (PALSAR) onboard Advanced Land Observing Satellite (ALOS) collected many SAR images since it was launched on 24 January 2006. The combinati...
