Coastal Tidal Flat Distribution Maps of China for 2016 and 2024 at 10 m Resolution

This dataset provides national-scale coastal tidal flat vector maps of China for 2016 and 2024, derived from dense time series Sentinel-2 imagery at 10 m spatial resolution. All available Sentinel-2 acquisitions within each target year were incorporated to construct dense time series. The dataset was produced using the fully automated hierarchical classification framework (TF-LMMO) described in the accompanying publication, and was validated with overall accuracies exceeding 95% (Kappa > 0.91). The dataset offers a consistent and reliable spatial baseline for coastal wetland monitoring, change analysis, and sustainable coastal management.
