ABSTRACT: During the communism, the accent of development was put mainly on industry. This is also the case of The Industrial Platform Săvineşti, from Neamţ county, which assured two major productions: textile fibers and chemical fertilizers. After the fall of the regime, the platform was divised and some of the new owners have sold all the equipments, have demolished the buildings, leaving the place barren. In the present, only a few of the old factories still work, and new stakeholders started their businesses. The study aims to show how the land surface temperature (LST) evolved in association with the events that followed from the flowering period of the factory. Three summer months from different years (1991, 2008 and 2018) where taken into consideration and LST was calculated based on Landsat scenes from missions 5-TM and 8-OLI. In order to make the whole process faster, two models were constructed using ArcMap extesion Model Builder. Besides the land surface temperature, there were calculated another two indices: Normalized Difference Vegetation Index (NDVI) and Normalized Difference Moisture Index (NDMI), which offer additional arguments to the changes that took place on the platform. The purpose of the study is to show how land surface temperature changes depending on the use of the territory, thus the importance of remote sensing being emphasised.
