Urban Area Change Analysis in the Rangpur Sadar Upazila, Bangladesh Using Landsat Imageries
Md. Shareful Hassan, Syed Mahmud-ul-islam
Abstract: Rangpur sadar Upazila has been becoming an important city in terms of administration, livelihoods, education and population migration from its nearest Upazilas. In this paper, temporal changes of the urban and agriculture areas were estimated using two multi-date Landsat imageries from 1989 and 2014. Two thermal imageries from the both years were also used to investigate Land Surface Temperature (LST). From this study, it is estimated that urban areas have increased by 20 % at annual growth rate while agriculture was only 3 %. This percentage of agricultural areas were converted from forest and wetlands. An increase trend of temperature was found in the area. The mean LST was 190C and 400C in 1989 and 2014 respectively. In order to understand the relationship between population growth and urbanization, we used a regression analysis, which was 92 %. The overall accuracy for urban and agriculture was 92 % and 95 % in 1989 and 2014 respectively.
