Global warming is a factor that has widened over the last period of time, so monitoring ground temperature is needed to take measures to prevent this phenomenon. In the hope of preserving life on earth and bring balance in our life, as we use to have it, it is up to our civic duty to share the essentials of the scientific research done, for the doctoral thesis and came with some ideas and suggestion, to help our community to reach our goal. The objective of the study will describe a methodology used for estimating the terrestrial surface temperature by means of the geographic information systems technology, using the two Landsat thermal bands, acquired by the Thermal Infrared Sensor (TIRS) installed on the Landsat 8 satellite platform. A case study on the administrative area of Cristuru Secuiesc, located in the South-West part of Harghita County, will be approached in the paper. The primary data base consists of thermal bands (band 10 and band 11) and multispectral bands (2, 3, 4, 5) from the Landsat 8 mission, taken with OLI (Operational Land Imager) and TIRS (Thermal Infrared Sensor) sensors. To carry out the study, the NDVI index will be calculated using the multispectral bands, while the thermal bands will be converted to several physical quantities in order to obtain the desired result. The paper describes the process of collecting data and processing it, to obtain valuable information on the surface temperature experienced by a computer, without the need for field measurements.
