Ground heat of geothermal energy is defined as hot water, steam or gas under pressure accumulated in the depths of the earth's crust. At the same time, geothermal energy is a sustainable, renewable, inexhaustible, natural energy source. Geothermal areas are reservoirs formed by the warming of the water in the rocks. Depending on the depth of the reservoirs, the temperature of the waters can vary with the ground surface temperature. Our country is very rich in geothermal energy and uses geothermal energy in many areas. For example, electrical power generation, heating of houses and greenhouses, thermal facilities (health tourism) and the like. Land surface temperature is a very important data for many studies. Especially in regions where the surface temperature is higher than the average surface temperature, the surface temperature of the land is analyzed with the help of thermal images obtained from satellites and surface temperature models of these regions are produced. Terrain surface temperature models are generated from the thermal bands of Sentinel satellite images. The Sentinel 3A satellite launched by the European Space Agency (ESA) into orbit makes it possible to directly determine the temperature change of the ocean and land surface thanks to the LST band. The surface temperature increase of Sentinel 3 images obtained at certain time intervals between the periods determined by using the Sentinel Application Platform (SNAP) was examined and the data obtained were analyzed. In this study, thermal bands of Sentinel satellite images were used to determine the land surface temperature of the geothermal area located near Kestanbol village of Ezine district of Çanakkale province. The obtained satellite images were analyzed using the Sentinel Application Platform (SNAP) software, and the temperature changes of the land surface at certain time periods were analyzed and the data obtained were analyzed. Land surface temperature maps of the geothermal area were created with ArcGIS software.
