geopandas.GeoDataFrame.to_parquet#

GeoDataFrame.to_parquet(path, index=None, compression='snappy', schema_version=None, **kwargs)[source]#

Write a GeoDataFrame to the Parquet format.

Any geometry columns present are serialized to WKB format in the file.

Requires ‘pyarrow’.

WARNING: this is an early implementation of Parquet file support and associated metadata, the specification for which continues to evolve. This is tracking version 0.4.0 of the GeoParquet specification at: opengeospatial/geoparquet

This metadata specification does not yet make stability promises. As such, we do not yet recommend using this in a production setting unless you are able to rewrite your Parquet files.

New in version 0.8.

Parameters:

pathstr, path object
indexbool, default None: If True, always include the dataframe’s index(es) as columns in the file output. If False, the index(es) will not be written to the file. If None, the index(ex) will be included as columns in the file output except RangeIndex which is stored as metadata only.
compression{‘snappy’, ‘gzip’, ‘brotli’, None}, default ‘snappy’: Name of the compression to use. Use None for no compression.
schema_version{‘0.1.0’, ‘0.4.0’, None}: GeoParquet specification version; if not provided will default to latest supported version.
kwargs: Additional keyword arguments passed to pyarrow.parquet.write_table().
