Google Earth Engine——该数据集是2018年30米分辨率的中国梯田分布地图。它是通过使用基于谷歌地球引擎平台的多源和多时空数据进行基于像素的监督性分类开发的。

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.
