چکیده
This paper proposes a useful technique for generating an earth resistivity map. Earth resistance is one of essential factors in a broad range of power system analysis and design. Information of earth resistivity is helpful for practical power system engineers in order to establish power system grounding. In this paper, a LANSAT7 image of a tested area of 50 km was used by ENVI program in associative with a set of resistivity data obtained from field measurement. By using the maximum likelihood for supervised classification of a mixed band 7, 5 and 3, highest value of 85.71% confidence was obtained. Key-Words: Earth resistivity, Wenner method, Satellite image technology, Power system grounding, Classification technique, Multispectral

Object-Oriented Method for Automatic Extraction of Road from High Resolution Satellite Images
As the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. This processing comprises two fundamental and critical steps towar...
متن کاملMonitoring the earth surface temperature and relationship land use with surface temperature using of OLI and TIRS Image
Earth surface temperature is an important indicator in the study of energy equilibrium models at the ground level on a regional and global scale. Due to the limitation of meteorological stations, remote sensing can be an appropriate alternative to the Earth's surface temperature. The main objective of this study is to monitor the surface temperature and its relationship with land use, which is ...
