  Change detection helps to determine the vicissitudes of land use/land cover properties by perceiving them in different times. Substantially, it includes the ability to measure temporal effects by utilizing multi-temporal data sets. In this research, Landsat satellite data is used to identify the temporal change by using diverse techniques of remote sensing and geographic information system. The current research is based upon Karachi Division to observe the spatial change of land use/land cover with urban land surface temperature and precipitation level in between the years 1998 and 2018 for the period of 20 years. Satellite imagery that is used to classify LULC features are for the years 1998, 2008 and 2018 for better visualization of the temporal situation. In this research, LULC area was observed to identify the changes in two decades from 1998-2008 and 2008-2018 and as whole era 19.. View More»
