Chinese Cropland Parcel and Boundary Dataset

In order to address the challenge of fine-grained land parcel extraction in complex agricultural landscapes in China, this study developed the China Farmland Parcel and Boundary Dataset (CCPBD). This dataset is based on 5-meter resolution remote sensing images and covers 679 representative sample areas from 31 provincial-level administrative regions in China (excluding Hong Kong, Macao, and Taiwan), with a total area of 40061 square kilometers and 999734 manually mapped independent cultivated land parcels. CCPBD not only provides high-precision vector data, but also supports pixel level structured labels, covering typical forms such as plain farmland, sloping farmland, and terraced farmland. It aims to provide a high-quality benchmark platform for the development, training, and evaluation of intelligent farmland extraction algorithms, and to assist in precision agriculture and fragmented land management
