| ## Geometry | |
| The parquet file in this folder | |
| (`brazil-sul.parquet`) has the same schema as the combined | |
| `combined/all_world.parquet`. Each row carries the polygon | |
| **geometry as WKT** (default), plus centroid + area + the | |
| whitelist-matched tag. | |
| Load with: | |
| ```python | |
| import pyarrow.parquet as pq | |
| table = pq.read_table("per_country/brazil-sul/brazil-sul.parquet") | |
| df = table.to_pandas() | |
| # df["geometry_wkt"] is a column of WKT strings; parse with shapely.wkt.loads | |
| ``` | |
