geopolars.from_arrow

geopolars.from_arrow(
    a: pa.Table | pa.Array | pa.ChunkedArray,
) -> GeoDataFrame | GeoSeries

Construct a GeoPolars GeoDataFrame or GeoSeries from an Arrow Table or Array.

This operation will be zero copy for the most part. Types that are not supported by Polars may be cast to the closest supported type.

Parameters:

• a (pa.Table | pa.Array | pa.ChunkedArray) –

  Data represented as Arrow Table or Array.

Returns:

• GeoDataFrame | GeoSeries –

  GeoDataFrame or GeoSeries

geopolars.from_geopandas

geopolars.from_geopandas(
    gdf: geopandas.GeoDataFrame
    | geopandas.GeoSeries
    | pandas.DataFrame
    | pandas.Series,
    force_wkb: bool = True,
) -> GeoDataFrame | GeoSeries | DataFrame | Series

Construct a GeoPolars GeoDataFrame or GeoSeries from a geopandas.GeoDataFrame or geopandas.GeoSeries.

This operation clones data.

This requires that geopandas and pyarrow are installed.

Parameters:

• gdf (geopandas.GeoDataFrame | geopandas.GeoSeries | pandas.DataFrame | pandas.Series) –

  Input data to convert from.

Returns:

• GeoDataFrame | GeoSeries | DataFrame | Series –

  A GeoPolars GeoDataFrame or GeoSeries
