Urban Growth Dynamics of Ghaziabad District using Remote Sensing

Abstract

Human activities are the primary cause of environmental changes, particularly in rapidly developing places. These changes in land use or land cover (LULC) can be evaluated by mapping the different land cover classes. This study aimed to assess the LULC dynamics of the Ghaziabad district of Uttar Pradesh using Landsat satellite imageries. Two time periods,i.e. 1992 and 2022,were taken into consideration to find the land variation. According to the findings, there has been a significant surge in the built-up category from 140 sq km to 223 sq km, whereas the surface covered by vegetation land decreased from 136 sq km to 101 sqkm showing a decline of 15.5% to 11.5% in 30 years.The study's  findings demonstrate the use of satellite digital image processing for locating and mapping LULC alterations.
