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.本数据集为中国首套1米分辨率国家级海滩地图数据集。该数据集以2025年6月获取的必应（Bing）航空影像为数据源，通过图像分类方法生成中国1米分辨率海滩地图。本数据采用伪墨卡托（Pseudo-Mercator）投影坐标系，地理坐标系为GCS_WGS_1984。数据集中的"Shape_Leng"字段代表海滩周长，"Shape_Area"字段代表海滩面积，"Province"字段用于标注各独立海滩所属的省级行政区。
