In this paper, we address the challenge of land use and land cover classification using remote sensing satellite images. For this challenging task, we use the openly and freely accessible Sentinel-2 satellite images provided within the scope of the Earth observation program Copernicus. The key contributions are as follows. We present a novel dataset based on satellite images covering 13 differe...

Some methodologies were compared in providing erosion maps of surface, rill and gully and erosion features, in research which took place in the Varamin sub-basin, north-east Tehran, Iran. A photomorphic unit map was produced from processed satellite images, and four other maps were prepared by the integration of different data layers, including slope, plant cover, geology, land use, rocks erodi...

The radiometric normalization of multi-temporal satellite optical images of the same terrain is necessary for land cover change detection e.g. relative differences. In previous studies, ground reference data or pseudo invariant features (PIFs) were used in the radiometric rectification of multi-temporal images. Ground reference data are costly and difficult to acquire for most satellite remotel...

Thermal infrared satellite sensor images are widely used for assessing the thermal urban environment as well as for identifying the Urban Heat Islands (UHI) in highly urbanized areas. In this study, the relationship between urban growth and UHI in the megacity of Istanbul was investigated using the Landsat 5 TM satellite sensor data and temperature recordings obtained from the meteorological st...

the persian gulf is northern part of the ropme sea area (rsa), and is semi-enclosed shallow sea which located in subtropical climate. measuring is 1000km in length, varying in width 60-340km, and average depth is about 35m and maximum depth is 105m. this research was carried out during 2005-2010 for reviewing the corals status and determination of coral reef habitats distribution in the persian...

For land cover classification and urban area analysis remote sensing techniques are gaining more importance. Numerous remote sensing techniques have been developed for analyzing the satellite images. The launch of Worldview-2 satellite with resolution of 0.5 m signaled the advent of high resolution satellite images. Such images offer an exciting possibility for feature extraction as well as com...

Comparison of the nucleotide sequences of cucumber mosaic virus (CMV) satellite RNAs, which induce necrosis on tomatoes, reveals a highly conserved region within their 3' halves. The sequence of WL1 satellite (WL1-sat) RNA, which attenuates CMV symptoms on tomatoes, differs from all necrogenic satellite RNAs at three nucleotide positions within this conserved region. These nucleotides were prog...

association of satellite rna with cucumber mosaic virus (cmv) leads to either attenuation or enhancement of the viral symptoms. for detection of the satellite rnas in iranian isolates of cmv, plant samples showing viral symptoms were collected from different farms in the provinces of east- and west- azerbayjan and ardebil. these samples were inoculated onto the experimental host plants in green...

Spatial and temporal information on urban infrastructure is essential requires various land-cover/land-use planning management applications. Besides, a change in has direct impact other land-cover climatic conditions. This study assessed changes the rate spatial distribution of Peshawar district’s its effects Land Surface Temperature (LST) during years 1996 2019. For this purpose, firstly, sate...
