Abstract :

The main purpose of this study was to monitor the surface temperature in relation to land use changes with surface temperature using OLI and TM images in the present study. It was used for 2020, and the Landsat 5TM satellite imagery was used to extract land use and its thermal band (band 6) was used to extract ground surface temperature for 1992. The monitored method was used to classify land use for 1992 and 2020 and land use changes and the maximum similarity method was used. The obtained results indicate the accuracy of the classification by the basic pixel method. According to the research findings, the total accuracy of the classification maps using the maximum similarity method was 99.84 for 1992 and 99.78 for 2020. According to the land use map of Sufi Chay watershed from 1992, which has been extracted by the maximum similarity method, most of the land uses are primarily related to the type 1 mountainous part, which has an area of approximately 320.42 square kilometers. Then, rainfed land use with an area of 191.09 square kilometers and dense agricultural land use with an area of 74.29 square kilometers have the most areas. The area of land uses in 2020 also shows that the most land uses are mountainous type 1 rainfed and residential. Keywords: Surface temperature, land use change, OLI, QGIS, Sufi chay.
