2026-07-17 GLC_FCS10AD land-cover dynamic dataset from 2017 to 2024 doi:10.57760/sciencedb.43265 en GLC_FCS10AD is the first global 10 m annual land-cover dynamics dataset with 30 land-cover classes covering 2017–2024. The dataset was generated using an AlphaEarth Foundation (AEF)-driven monitoring framework that integrates adaptive change detection, localized land-cover updating, and spatiotemporal consistency optimization to produce temporally consistent annual land-cover maps. Validation using globally distributed annually interpreted reference samples demonstrates an overall accuracy of 84.23%–84.42%, while independent third-party validation over the United States achieves 87.64%–87.72% overall accuracy. GLC_FCS10AD provides detailed information on annual global land-cover changes and supports applications in global change research, ecosystem monitoring, carbon-cycle assessment, biodiversity conservation, agricultural monitoring, and sustainable land management.
