## Geometry

The parquet file in this folder
(`bulgaria.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/bulgaria/bulgaria.parquet")
df = table.to_pandas()
# df["geometry_wkt"] is a column of WKT strings; parse with shapely.wkt.loads
```

## Notes

Sofia, Plovdiv, and the Black Sea coast have dense landuse and building footprints; mountain areas (Rila, Pirin, Rhodopes) are better-mapped for hiking.
