This dataset is a China terrace map at 30 m resolution in 2018. It was developed through supervised pixel-based classification using multisource and multi-temporal data based on the Google Earth Engine platform. The overall accuracy and kappa coefficient achieved 94% and 0.72, respectively. This first 30 m China terrace map can be used for studies on soil erosion, food security, biogeochemical cycle, biodiversity, and ecosystem service assessments.
