Urbanization directly affects the existing infrastructure, landscape modification,
environmental contamination and traffic pollution especially if there is lack of urban
planning. Recently, the rapid urban sprawl has resulted in less developed green areas and
has devastating environmental consequences. This study was aimed to study the past urban
expansion rates and Measure LST from satellite data. The Land use land cover (LULC)
maps of years 1996, 2010, 2013, and 2017 were generated using Landsat satellite images.
Four main classes i.e. water, urban, bare land and vegetation were identified using
unsupervised classification with iterative self-organizing data analysis (isodata) technique.
The LST from satellite thermal data can be derived from different procedures:atmospheric,
radiometric calibrations and surface emissivity corrections, classification of spatial
changeability in land-cover. Different methods and formulas were used in the algorithm
that successfully retrieves the land surface temperature to help us study the thermal
environment of the ground surface. To verify the algorithm, the land surface temperature
and the near-air temperature were compared. The results showed that, From 1996-2017
urban areas increased to about considerable increase of about 48%.few areas of city also
shown in reduction in LST from year 1996-2017that actually began their transitional phase
from rural to urban LULC.Mean temperature of city increased averagely about 1ºC each
year in the month of October. The green and vegetative areas witnessed a decrease in area
while higher number of pixels increased in urban class.
