Abstract | spatial growth of population and human settlement is a universal process. The objective of this research is to analyze the urban growth of Bhaktapur district using the Landsat satellite Images of 1988, 1998, 2010 and 2015. Bhaktapur district has been selected as the study area for this study. Bhaktapur has undergone a radical change in its physical form, not only on its vast urbanized territorial expansion but also through an internal physical transformation over the last decades. Unsupervised classification technique followed with correction according to the supporting documents was applied to prepare the land cover map with five land cover classes. The study showed that almost all the land cover components have changed (gains or losses) according to the time into one another. Especially in last 5 years. The increase in built-up area is prominent in Bhaktapur district over the years (1989-2015).The built-up area increased from 1.8% to 24.0% of the total study area in between 1988 and 2015. The rate of urbanization was dramatic in between 2010 to 2015. About 12.9% of the total study area was converted into the built-up area in last 5 years period alone. Expansion of road might be one of the main factors, which increased the urbanization dramatically. |
