Abstract. Global warming is getting more and more attention, and one of the main reasons is the rapid growth of the surface temperature. Today more than fifty percent of the human population is living in the cities, and with the growing tendency by the year 2050 to seventy percent, urbanisation is becoming one of the main factors of global warming. Conducted research indicates that the heat island effect is increasing rapidly in a territory with fast urbanisation growth. The surface temperature and air temperature are increasing in surrounding rural areas. This research aims to analyze urbanisation's impact on creating heat islands in a specific time frame from 1990 until 2020 in five large cities with satellite imagery obtained from Landsat satellite missions. By conducting the land cover classification and interpretation of vegetation indexes with the help of GEE (Google Earth Engine) and GIS tools as well as their changes in time by using different channels of satellite imagery will try to show the correlation between urbanisation and heat islands. This research is important for the professional and academic society because the control of global warming and increasing the quality of life in cities is today's priority.
