Land use land cover change of Sundarbans mangrove from 1975 to 2020

This study aims to explore the land use (LULC) change over time in the world’s largest mangrove forest, Sundarbans, from 1975 to 2020 using Landsat Satellite images. The accuracy of the LULC classification is explored, and consequential thematic changes analysed. Standard methods for radiometric calibration, atmospheric correction, mosaicking effect mitigation, and rectification are used. The maximum likelihood classification algorithm provided LULC maps at four time periods over 45 years (1975, 1990, 2005, and 2020).
