Abstract

In general, population growth, urbanization, and the industrialization of cities have an important effect on air temperature in the area. To study land use and temperature changes, Landsat 8 satellite images were used for the years 1991 and 2016 at the beginning and end of a 25-year period, and after reprocessing, Support Vector Machine (SVM) classification and Vegetation Index (NDVI) were applied. The Kappa coefficient index (for 1991=0.88, and 2016=0.92) and overall accuracy (for 1991=90.90, and 2016=93.75) were used to assess the accuracy of the classification. Results showed that vegetation, water, and land were decreased by 16.14, 6.12, and 13.51 percentages, respectively and urban and road areas were increased by 28.4 and 7.33 percentages, respectively. On average, real and estimated temperatures were increased by 3.7 and 4.52 °C during the period, respectively. Also, the RMSE (1.26) represents an incremental direct relationship between industrialization and LST.
