This dataset is mainly sourced from Amap (www.amap. com) and obtained through the transformation and processing of JSON boundary data.
1) Download JSON data of provincial, municipal, and county administrative boundaries using the API provided by Gaode Open Platform;
2) Develop a program to correct JSON;
3) Synthesize JSON boundary data from various regions and convert it into vector data in GPKG format;
4) Supplement the missing boundary data within each administrative region to ensure the completeness of the administrative regions in each document.
Good data quality and accurate boundaries.
