The Impact of the Green Spaces On the Land Surface Temperature in Urban Areas - Analysis of the Land Surface Temperature in the City of Oradea using Landsat 8 Satellite Images

Abstract

People living in urban areas face temperature discomfort due to the urban heat island phenomenon that is in correlation with the land surface temperature (LST) generated by the buildings for living and other construction. In this paper, we aim to use remote sensing data to retrieve the LST values to demonstrate the visual correlation that exists between these values and green spaces. To retrieve the LST values and to obtain the raster dataset necessary to identify the correlation between the green spaces and these values, we applied the method of single window algorithm using data from Landsat 8, acquired on 27th May 2021, in ArcGIS software for the City of Oradea area. The obtained results confirmed the strong correlation between green spaces and low values of land surface temperature.
