摘要：Consistent and appropriate change detection of topographic features offers the framework for evaluating the links and interconnections between anthropogenic and natural processes for sustainable resource management. This investigation seeks to reveal the present land use/land cover and their transition pattern between 2009 and 2019 utilizing Landsat TM and Landsat 8 OLI imagery through the process of change detection techniques. ArcGIS v 10.8 and ERDAS Imagine v14 were utilized to interpret satellite imagery and analyze quantifiable information for land-use change estimation of the research region, Berhampore block. Maximum Likelihood Classifier (MLC), Raster-based analysis, Vector-based analysis, and Image Differencing have been used to evaluate the results of the transformation during the study period. The result indicates that during the period of 2009 and 2019, built-up, vegetation, and barren land have been increased while agricultural land and water bodies have been decreased. Finally, the study would also recommend the policymakers to keep an eye on the prevailing situation of present land use and land cover in order to preserve existing plants, prevent the uneven expansion of the built-up area, and protect the natural ecosystem.
