## vectools.save_and_read_parquet()


Save a GeoDataFrame as a GeoParquet file and read it back for verification.


Usage

``` python
vectools.save_and_read_parquet(
    gdf,
    out_path,
)
```


## Parameters


`gdf: gpd.GeoDataFrame`  
The GeoDataFrame to be saved.

`out_path: str or Path`  
The file path where the GeoParquet file will be saved.


## Returns


`gpd.GeoDataFrame`  
The GeoDataFrame read back from the saved GeoParquet file.


## Notes

The function ensures that the output directory exists before saving. It uses the 'pyarrow' engine for writing the Parquet file. The write is staged to a unique sibling temp file and atomically moved into place, so a crash mid-write cannot leave a truncated file at `out_path`.
