نبذة مختصرة : Lahore, Punjab’s provincial capital and 2nd largest metropolitan city of Pakistan, is facing an increasing population and migrational trend from rural to urban areas and socio-economic development resulting in rapid urbanization and Land Use Land Cover (LULC) changes recently. Rapid urban growth has influenced the Land Surface Temperatures (LST) causing Urban Heat Island (UHI) effect. The present research is an effort to estimate the LULC changes and their influence on the Land Surface Temperature mainly using remotely sensed satellite data and Geographic Information System (GIS). Satellite data from Landsat 5 TM data was considered for the year 2010 and Landsat 8 OLI/TIRs data was taken for years 2015 and 2020. Supervised LULC classification was performed for May 2010, May 2015 and May 2020 using the QGIS-SCP plugin. LST temperatures were estimated using thermal infrared bands of the satellite imagery. Comparison of LULC classification of 2010, 2015 and 2020 reveals that the built class is increasing and vegetation is shrinking. A positive correlation has been noticed between increasing population and urbanization. Population density and area of built class/person is increased over the decade. The study of the LST reveals that the built class has the highest temperatures and several hot spots denoting the highest temperatures are observed over the built class showing that it is the biggest contributor to UHI effect. The integration of remote sensing techniques and GIS is an efficient tool for monitoring and evaluation of urban expansion and its influence on LST.
