The first 1-m China's national-scale sandy beach map in 2025 derived from high-resolution satellite imagery

This is China's first 1-meter resolution national-scale beach map dataset. Based on Bing aerial imagery acquired in June 2025, the 1-meter resolution beach map of China was generated using the image classification method. The projected coordinate system of this data is Pseudo-Mercator, and the geographic coordinate system is GCS_WGS_1984. The "Shape_Leng" field in the dataset represents the beach perimeter, the "Shape_Area" field represents the beach area, and the "Province" field represents the affiliated province of each independent beach.
