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.
