Harmonized global land cover maps at 10 m (2020) and 30 m (annual, 2020 to 2024) resolutions were generated using a deterministic, rule-based ensemble framework that integrates primary spatial backbones with specialized thematic and contextual layers. Using LCM-10, GLAD GLCLUC, and GLC_FCS30D as baseline inputs, the workflow sequentially applies prioritized conditional rules to refine generic categories into up to 44 detailed hierarchical classes. The classification incorporates specialized crop, grassland, forest, and coastal datasets, along with topographic, spectral, and coastal-distance variables, to account for landscape contexts.
