Abstract
This research aims to analyze temperatures for periods of heat waves using the Earth's surface temperature index (LST) and linking it to the vegetation density index data (NDV), using GIS techniques, and using the data of the LANDSAT 8 satellite visuals represented by Band 10 - Thermal Infrared (TIRS) to estimate the temperature The temperature of brightness, and the two bands Band 4 - Red and Band 5 - Near infrared (NIR) were used during the heat waves in July, August and September of 2020. The study concluded that the surface temperature of the earth ranged between 40-48 m and constituted approximately 70% of the area The totality, which was recorded during the months of August and September, while the surface temperature, which ranged between 27-43 degrees, constituted approximately 30% of the total area, which was recorded during the month of July. As for the NDVI vegetation index, it turned out that the negative values are low compared to the positive values, which indicates the existence of lands with moderate vegetation cover. Thus, the rise in temperatures affects the open areas with no vegetation cover more than the areas with vegetation cover.
