Satellite images are commonly used for defining thermal urban environment and heat islands in urban areas. The objective of this study was to analyze and evaluate thermal environment of Uzundere-Erzurum using satellite images provided by the Landsat Thematic Mapper (TM) sensor on board Landsat 5 satellite. In respect to land use and urban surface features, spatial characterization of thermal urban environment was defined. In order to define the link between surface emissivity, land surface temperatures (LST), and urban surface characteristics more effectively, the CORINE Land Cover (CLC) database for Uzundere was also used. Based on the Landsat satellite images, different land cover categories are defined, and the alterations of heat islands are identified according to these categories. The minimum and maximum surface temperatures were obtained from open spaces, non-vegetated bare rocky areas (- 1.8 and 29.1 °C, respectively). The surface temperature in the water areas was much better (7.5 and 21.9 °C) and followed by green areas surface temperature (- 0.9 and 28 °C). Surface temperatures should be considered energy-focused planning.
卫星图像常用于定义城市热环境和城市热岛。本研究的目的是利用搭载在 Landsat 5 卫星上的 Landsat 专题制图仪 (TM) 传感器提供的卫星图像，分析和评估厄曾德雷-埃尔祖鲁姆的热环境。根据土地利用和城市表面特征，对热环境进行了空间特征描述。为了更有效地定义表面发射率、地表温度 (LST) 和城市表面特征之间的关系，还使用了厄曾德雷的 CORINE 土地覆盖 (CLC) 数据库。根据 Landsat 卫星图像，定义了不同的土地覆盖类别，并根据这些类别识别热岛的变化。从开阔地和无植被裸露岩石区获得的最低和最高表面温度分别为（-1.8 和 29.1°C）。水域的表面温度要好得多（7.5 和 21.9°C），其次是绿色区域的表面温度（-0.9 和 28°C）。表面温度应作为以能源为重点的规划考虑因素。
