to determine the suitable indices for vegetation cover and production assessment based on the remote sensing data, simultaneous digital data with field data belonging to the spring rangeland of the semirom-isfahan province were analyzed. during two years of monitoring the annual, grass, forb, and shrub vegetation cover and the total production data from 86 were collected. the global positioning...
Background and Aim: Arthropod-borne diseases are one of the major causes of human mortality. Since launch of the first meteorological satellites in 1960s, remote sensing has been increasingly implicated in the field of human health research and the data from satellites and their sensors with different spatial and temporal resolutions opened a new field of research in human health for scientists...
mineral dust can directly affect the solar and terrestrial radiation in both visible and infrared (ir) spectral regions through scattering and absorption processes. due to specific optical properties of dust particles, satellite observed radiances carry the spectral signatures of dust particles that are different from molecular, cloud, and underlying surface. based on these differences, various...
Development of new pattern recognition techniques for the analysis of data collected from satellites and airborne sensors used for Earth observation has been a popular research topic for several decades. Consequently, the pattern recognition and remote sensing research fields have always overlapped. However, the large volumes of remote sensing data acquired from last generation sensors require ...

Analyzing the Spatial Pattern of Drought in Central and South Zagros Using Remote Sensing Indicators
Introduction: As a complex phenomenon occurring due to a long period of poor precipitation, drought causes water scarcity in the soil and the hydrological system via hydrological, bringing about long-term consequences which may lead to severe economic, environmental, and social problems worldwide. Droughts are classified into four types: meteorological (rainfall), agricultural (soil’s moisture)...
sarbisheh mineral occurrence is located in the vicinity of the tourshab village about 50 km south of birjand, the center of southern khorassan province, east iran. the predominant geologic characteristics of the region are highly-tectonic deformation, and intrusive, granodiroritic-dioritic, to volcanic, dacitic-andsitic rocks associated with broad alteration. to the northern part of the studied...
emissivity mapping of the earth’s surface is the prerequisite to thermal remote sensing. a precise determinationof a surface's temperature is dependent upon the availability of precise emissivity data for that surface. the presentstudy area is a part of sugarcane plantation fields in the west part of khuzestan province. in this work, temperatureemissivity separation algorithm (tes) was applied ...
