  • pyogrio writes EMPTY geometries to gpkg, fiona writes None.
import geopandas as gpd`
import shapely`

gdf = gpd.GeoDataFrame(geometry=[shapely.Polygon()], crs=31370)`
gdf.to_file("test_fiona.gpkg", engine="fiona")`
gdf.to_file("test_pyogrio.gpkg", engine="pyogrio")`
print(f'{gpd.read_file("test_fiona.gpkg", engine="pyogrio").geometry.item()=}')`
print(f'{gpd.read_file("test_pyogrio.gpkg", engine="pyogrio").geometry.item()=}')`

print(f'{gpd.read_file("test_pyogrio.gpkg", engine="fiona").geometry.item()=}')`

Output:

gpd.read_file("test_fiona.gpkg", engine="pyogrio").geometry.item()=None
gpd.read_file("test_pyogrio.gpkg", engine="pyogrio").geometry.item()=<POLYGON EMPTY>
gpd.read_file("test_fiona.gpkg", engine="fiona").geometry.item()=None
gpd.read_file("test_pyogrio.gpkg", engine="fiona").geometry.item()=<POLYGON EMPTY>
