geopandas.GeoDataFrame.from_arrow

classmethod GeoDataFrame.from_arrow(table, geometry=None, to_pandas_kwargs=None)

Construct a GeoDataFrame from a Arrow table object based on GeoArrow extension types.

See https://geoarrow.org/ for details on the GeoArrow specification.

This functions accepts any tabular Arrow object implementing the Arrow PyCapsule Protocol (i.e. having an __arrow_c_array__ or __arrow_c_stream__ method).

Added in version 1.0.

Parameters:

tablepyarrow.Table or Arrow-compatible table

Any tabular object implementing the Arrow PyCapsule Protocol (i.e. has an __arrow_c_array__ or __arrow_c_stream__ method). This table should have at least one column with a geoarrow geometry type.

geometrystr, default None

The name of the geometry column to set as the active geometry column. If None, the first geometry column found will be used.

to_pandas_kwargsdict, optional

Arguments passed to the pa.Table.to_pandas method for non-geometry columns. This can be used to control the behavior of the conversion of the non-geometry columns to a pandas DataFrame. For example, you can use this to control the dtype conversion of the columns. By default, the to_pandas method is called with no additional arguments.

Returns:

GeoDataFrame
