Awareness of the process of environmental change, which has intensified due to extensive human activities, and now, the use of satellite imagery to study environmental and spatial changes is known as the best example for detecting and evaluating changes. Because with the advances made in this technology and the production of satellite images with high spectral and spatial resolution, as well as various image processing techniques, environmental and spatial changes can be estimated and managed. In this study, changes are examined. Temperature (day and night) and vegetation of YASOUJ city, which is in a period of 20 years, and for this purpose, using software (Giovanni NASA) and (Google earth) to capture satellite images in four five-year periods (2020 - 2000) has been done. According to the research and studies were done from the current research, there is a phenomenon (global warming) and our planet due to our activities as humans, we have caused global warming and over time this trend is intense and strong. It takes more. The intensity of temperature changes in urban environments is more. پرونده مقاله
