Regional mapping and monitoring land use/land cover changes: a modified approach using an ensemble machine learning and multitemporal Landsat data

Geocarto International, 2023
Regional mapping and monitoring of land use/land cover (LULC) still remain a challenge that depend on classifier and remote sensing data selected. This study aims to create precise LULC maps and explore the efficiency of an ensemble machine learning ...
