Shapely

For interoperability with Shapely, use WKB methods as shown below.

import geoarrow.rust.core
import shapely

shapely_geoms = shapely.from_wkb(geoarrow.rust.core.to_wkb(geoarrow_array))
geoarrow_array = geoarrow.rust.core.from_wkb(
    shapely.to_wkb(shapely_geoms, flavor="iso")
)

Note

geoarrow.rust.core.from_wkb and geoarrow.rust.core.to_wkb do not yet work on chunked arrays. To use with a chunked array, operate on each chunk:

import geoarrow.rust.core
import shapely
import pyarrow as pa

table = geoarrow.rust.core.read_geojson("...")
chunked_geoarrow_array = table.geometry
shapely_geoms = shapely.from_wkb(
    pa.chunked_array(
        [
            geoarrow.rust.core.to_wkb(chunk)
            for chunk in chunked_geoarrow_array.chunks()
        ]
    )
)

It will be fixed to work with chunked arrays in the future.
