MCHCD: A multi-source Chinese high-resolution satellite benchmark dataset

The MCHCD dataset incorporates ten types of high-resolution Chinese satellite imagery, including Gaofen-1 (A–D), Gaofen-2, Gaofen-6, Ziyuan-3, Ziyuan-302, and the China–Brazil Earth Resources Satellite-04 (CBERS-04), with spatial resolutions ranging from 3 to 10 meters and coverage across the entire territory of China. The complete MCHCD dataset consists of 415 scenes, which are divided into 75 labeled training scenes, 71 labeled test scenes, and 269 unlabeled test scenes. Due to data volume constraints, the current Zenodo repository only hosts the labeled training and labeled test subsets (146 scenes in total). The unlabeled test subset (269 scenes) is provided separately via https://pan.baidu.com/s/1D_zceV-NSEo5FyN3jlNkcw?pwd=y6cy (access code: y6cy).
