The monitoring of large areas by using satellite technique is very useful in the context of sustainable development and efficient and secure management. Satellite methods and techniques are increasingly used in studying and monitoring land and vegetation. There is very useful spectral information with great precision in characterizing large areas of land. This study is used for analyzing and determining how one of the most important parameters that could be obtained based on satellite images and the spectral frequency spectrum of the thermal surface in the thermal area, which is named the surface temperature of the ground. The studied area was Timisoara, and the LST parameter was determined using a specialized GIS software based on images from Landsat 8. Landsat 8 is an American Earth Observation Observatory launched on February 11, 2013 and an infrared thermal sensor TIRS) with two thermal bands. Starting from Landsat 8 satellite images and bands 10 and 11, the information spectrum describing the studied area was extracted and mathematical algorithms were processed, the LST parameter was determined to characterize the studied area. This study is also used to analyse how the soil surface temperature is determined based on Landsat 8 satellite imagery and a terrain surface response spectrum. To detect certain temperature categories of a surface or object, the radiation emitted by this electromagnetic spectrum is measured with thermal infrared.
