TEMPORAL AND SPATIAL ANALYSIS OF CLASSIFICATION TREE FOR IMPERVIOUS SURFACE MAPPING FROM SENTINEL-2 MSI DATA

Urban areas are expanding rapidly worldwide, but inconsistent definitions make cities hard to compare. This study created a new dataset mapping urban built-up areas for 1,611 cities from 2000 to 2025 using satellite imagery and population data. A unified definition of urban settlements allows fair comparisons across countries and time. The results show how land consumption and population growth are linked across regions, supporting global monitoring of sustainable development.
