Investigating Land Surface Temperature and Vegetation Indices Changes Using Landsat Data: A Case Study of Iaşi County

Paul MACAROF, Cristian-Iulia BIRLICA


The main purpose of this paper is to investigate the change of land surface temperature between 1994 and 2016, for Iaşi county, using remotely sensed data. Also in this research the changing of vegetation indices (VI) is investigated. LST is an estimate of ground temperature and the important to identify change in environment. Vegetation indices are quantitative measurements indicating the vigor of vegetation. The advantages of using remotely sensed data are the availability, consistent and repetitive coverage and capability of measurements of earth surface environment. Among them Landsat is the most popular one. The images taken, at 1994/2003/2013/2016, by Landsat-5 TM and Landsat 8- OLI satellites were used as the basic data source. The obtained results showed that temperature, for Iaşi county, increased about 7ᴼC between 1994 and 2016. Also, during the same period, the VI (NDVI, EVI, SAVI and MSAVI) analysis shows a decrease in dense vegetation and an increase in urban areas
