Abstract – This study introduces two applications of remotely sensed data to detect degraded areas and to evaluate the relative pollution produ...

to identify an appropriate index for monitoring and evaluation of drought, rainfall data obtained from meteorological stations of ilam province from 2000 to 2011 and modis satellite images with 16-day intervals were collected and processed. the standardized precipitation index (spi) was calculated based on rainfall data; therefore, the rainfall data were used for measuring spi and satellite ima...

Designing a social responsibility assessment model with network data envelopment analysis approach (Case study: public hospitals in Yazd province)

the changes in time and location of surface temperature from a water body has an important effect on climate activities, marine biology, sea currents, salinity and other characteristics of the seas and lakes water. traditional measurement of temperature is costly and time consumer due to its dispersion and instability. in recent years the use of satellite technology and remote sensing sciences ...

BACKGROUND Cancer incidence rate is increasing in the world particularly in developing countries. The awareness regarding cancer incidence and distribution helps policy makers and researchers to design comprehensive plan for controlling cancer. The aim of this study was to determine the incidence rate and trend of cancer in Yazd Province, central Iran. METHODS Data from Yazd cancer registry w...

   Current study monitored Electerical Conductivity (EC) as soil salinity index and Organic Matter (OM) in the area of Harat in Yazd, Iran, through remote sensing technology with high spatial and spectral resolution. The images were selected from IRS, LISS III satellites between the years 2008 and 2012. After preprocessing and analyzing the images, the relationship between parameters of (EC) an...

This paper reports on an investigation of radiometric calibration errors due to differences in spectral response functions between satellite sensors when attempting cross-calibration based on near-simultaneous imaging of common ground targets in analogous spectral bands. Five Earth observation sensors on three satellite platforms were included on the basis of their overpass times being within 4...

For the hydro power companies it is of major importance to know the magnitude of the spring flood. Hence, the amount of snow is crucial for forecast modelling. In mountainous areas with plenty of snow, the meteorological network is often sparse, and they lack direct observations of the snow pack. Therefore, if it is possible to combine satellite snow cover area information with a hydrologic mod...
