全国省市县三级行政区。gpkg格式矢量数据。数据集包含：
1）省域边界.gpkg;
2)市域边界.gpkg;
3)县域边界.gpkg。", "ds_source": "
本数据集主要来源于高德地图（www.amap.com）， 经对json边界数据进行转换加工获得。", "ds_process_way": "
1）利用高德开放平台提供的API分别下载省市县三级行政区边界JSON数据；\n
2）编制程序对JSON进行校正；\n
3）合成各区域JSON边界数据并转换为GPKG格式矢量数据；\n
4）对各行政区内缺失的边界数据进行补充，保证各文件中行政区域的完整。", "ds_quality": "
