Ground surface temperature is one of the important criteria in regional and regional planning. Surface temperature can be used in many environmental, agricultural, meteorological and other applications. In this research, Landsat 8 satellite images have been used to monitor the surface temperature in Dezful city. After performing radiometric corrections to calculate emissions based on vegetation and soil fraction (PV), emission calculations were performed based on FVC. As a result, ground surface temperature was estimated using a separate, single-channel window algorithm. While the separate window method shows a much higher value than the Planck method a very low value. It seems that the error of these two methods is much more than other methods. According to the approximate temperature extracted from the synoptic stations of Dezful city, the value of which is considered to be 308.95 Kelvin. But in general, it should be noted that the methods of calculating LST through satellite images are very different from the temperature obtained from meteorological and synoptic stations and do not offer high accuracy.
