Analysis of Sentinel 3 images of SLSTR sensors in identifying urban heat islands and its relationship with vegetation (Case study: Kermanshah)

This issue has become more apparent in large cities and provincial capitals, which have undergone land use changes in recent years. The main purpose of this study is to investigate the spatial relationship between the distribution of thermal islands with urban vegetation and compare the intensity of thermal islands in minimum, maximum and average values in urban areas of Kermanshah during the last 10 years. Data were analyzed using Sentinel 3 satellite imagery and SLSTR sensor with a spatial resolution of 500 m in the reflective bands and 1000 m in the thermal band using SNAP and QGIS software. Therefore, continuous monitoring of land use change is one of the main challenges of urban planning and management in metropolitan areas. Because the increase of green space in the city significantly reduces the temperature of the city and thermal islands. The key findings of this research are focused on three areas: first, focusing on the fair distribution of green spaces in the city, second, using waste spaces to increase green spaces, and finally, avoiding additional burden on the ground, because in dense areas, the possibility of creating thermal islands is much higher. It was from other places.
