Abstract :
Global warming has obtained more and more attention because the global mean surface temperature
has increased since the late 19th century. As more than 50% of the human population lives in cities,
urbanization has become an important contributor to global warming. The changes in land use/cover
include loss of agricultural lands, loss of forest lands, increase of barren area, increase of impermeable
surface of the area because of the built-up area, etc. The development of land use land cover is very
much useful to the city planner and policymakers. For the sustainable urban ecosystems, the amount of
land required for growing the vegetation can be estimated from these studies. One of the major
implications of urbanization is an increase in surface temperature and development of Urban Heat
Island. Surface temperature is increased by anthropogenic heat discharges due to energy consumption,
increased land surface coverage by artificial materials having high heat capacities and conductivities,
and the associated decrease in vegetation and water pervious surfaces which reduce the surface
temperature through evapotranspiration. Landsat8 images are widely used to observe the land surface
temperature. In addition to the development of land use/cover maps band, 6 of the Landsat8 imagery is
useful for deriving the surface temperature. Several researchers used Landsat8 imagery to develop land use/cover images as well as temperature images.
