Many investigations have shown thermal data obtained from sensors have extensive applications in the study of earth features. But based on the author’s information, the use of thermal remote sensing has not been widespread yet. Temperature is important factor in understanding some physico-chemical and biological properties, which can be used for describing the state of materials. Therefore, decision for selecting thermal remotely- sensed data and sensor types is a crucial step in the environmental studies. So, it is necessary that the content of thermal band information and their applications be evaluated. In this study, the advantages of thermal remote sensing and its applications in the study of sustainable development, vegetation, climate, air quality, soil and seismology are discussed. Based on the obtained results it may be concluded that thermal remote sensing data are powerful tools for environmental studies.
