Abstract
To assessed remotely data remote sensing and GIS methods was basic to accuse and
analysis of the thematic area, like the impacts of vegetation cover change of land surface
temperature. But there is a problem on calculating and evaluating the influence of
change in vegetation cover on the change of climate. Then, this study was conducted the
impacts of vegetation cover change on land surface temperature using remote sensing
and GIS methods. The study area was in south which is high populated and more
highland. Data was extracted from land satellite images like Landsat 5, Landsat 8
Operational Land Imager/ Thermal Infrared Sensor (OLI/TIRS). Thematic Mapper
Sensor (TM) and Climate Moderate Resolution Imaging Spectroradiometer (MODIS)
(and also ground truth data was used to verify remotely sensed data, additionally
Pearson Correlation coefficient was conducted to calculate and to analyze the
relationship of vegetation cover with LST. The final output presented that vegetation
cover occupied an area of 227979.09 ha (15.6%),154424.43 ha (12.5%), and 195231.59
ha (13.3 %) in 1985, 2000 and 2018, respectively where 3.1% of vegetation cover has
been lost in the last 33 years in in the study area.
