| Abstract | ||||
| In order to control urban growth, Egypt resorted to establishing new cities on the boundaries of existing ones. Thus, there is concern that the urban heat island phenomenon (UHI) will increase in these desert cities as their urban growth This phenomenon is dependent on land surface temperatures (LST), which are difficult to measure over large areas in situ. As a result, this research is focused on two primary objectives. The first objective is to establish a framework for examining the relationship between urban growth and LST over time using freely available data from remote sensing (RS) and geographic information systems (GIS). The second objective is to validate and apply this framework in order to ascertain the impact of changes in urban growth on the LST of 6th of October City, which will serve as a case study for new cities. Satellite images for the years 2001, 2007, 2013, and 2019 were obtained using the Landsat data source. Hence, the Land Use/Land Cover Classification (LULC) was obtained with excellent Kappa values of 0.973, 0.962, 0.962, and 0.968, respectively. By examining the relationship between LST and urban growth, the framework was able to produce satisfactory results regarding the impact of urban growth on UHI. It was discovered that as urbanization increases, the city's average LST decreases. This is because it increases the likelihood of shading and the presence of green spaces, rather than desert areas that absorb the most radiation. Thus, urbanization does not endanger UHI in new cities | ||||
