Monitoring The Land Surface Temperature and Its Correlation with NDVI of Chiniot by Using GIS Technology and Remote Sensing

Abstract

The unplanned and rapid increased in unban area have changed the atmospheric conditions and the non-urban area have less warm as compare to urban areas. In study area little portion of Chenab River include and the river bed contains the sand it shows high temperature value due to its specific heat energy. For this study Lands at-5 (February2000), Landsat-7(February 2005,2010) and Landsat-8 (Feb2015, Feb2020, Feb2022) Data acquired from USGS. The LST and NDVI correlation is negative and it is clearly seen that in the analysis of Landsat-8 (OLI/TIRS) the Land Surface Temperature is increases 3.5408o C from 2015 to 2022. The analysis of Landsat-7(ETM+) the Land Surface Temperature is increases 3.3461o C from 2005 to 2010. In the Correlation analysis(LST&NDVI) the most of vegetation occurs between 11 o C to 28 o C.
