Abstract: The use of multi-temporal satellite images in digital change detection algorithms aids in the comprehension of landscape dynamics. This study presents the spatiotemporal dynamics of land use and land cover in Kokrajhar District, Assam, India. Landsat Satellite images of four different periods. i.e., Landsat Thematic Mapper (TM) images from 1991, 2001, 2011, and 2021 were acquired from the Google Earth Explorer site and used to quantify changes in the Kokrajhar district over the 30 years from 1991 to 2021. Supervised classification methodology has been employed using the maximum likelihood technique in the ArcMap 10.8 Software. The images of the study area were categorised into four different classes: vegetation, agriculture, built-up, and water body. The results indicate that during the last three decades, built-up regions have increased by 3.8% (658.75 km²), while agriculture, vegetation, and water bodies have decreased by 0.74% (708.9 km²), 0.56% (1494.46 km²), and 2.46% (273.5 km²), respectively.
