Abstract

Earth surface temperature has been used in a wide variety of scientific studies including climatology, astronomy, meteorology, hydrology, ecology, geology, and medical sciences. The design and optimization of transportation network and site selection of conflagration and particularly in the calculation of the actual evapo-transpiration we require such data. Considering the earth's surface temperature monitoring in a limited number of meteorological stations to the distribution point we need to place and estimate the surface temperature in a wide area, and at the same time the surface temperature. To access the earth's surface temperature and classification the SEBAL and decision tree algorithm was used. Using ETM+ images dated 31 August 2000 and pre-process, files were ready for implementation of SEBAL method. Processing of the above mentioned software was through Envi4.5 and ArcGIS 9.3. This paper estimates the temperature differences if less than 5.57°C between a satisfactory level through remote sensing and statistics, while we estimated temperature measured from ground level for a period of 12 years (1993-2005) at Maragheh meteorological station. Results indicate that temperature estimates through remote sensing and such studies are applicable for earth science research and the environment.
