## Geometry

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

## Notes

Large Southern African country on the Atlantic coast, former Portuguese colony, with a long coastline from the Congo River mouth in the north to the Namib Desert in the south. Capital Luanda has good OSM coverage; the interior is sparsely mapped. Geofabrik /africa/ PBF (~81 MB). Notable protected areas include Iona National Park (in the Namib fringe), Kissama (Quiçama) National Park near Luanda, and the Calandula / Kalandula waterfalls.
