geopandas.GeoSeries.to_json#

GeoSeries.to_json(show_bbox=True, drop_id=False, to_wgs84=False, **kwargs)[source]#

Returns a GeoJSON string representation of the GeoSeries.

Parameters:

show_bboxbool, optional, default: True: Include bbox (bounds) in the geojson
drop_idbool, default: False: Whether to retain the index of the GeoSeries as the id property in the generated GeoJSON. Default is False, but may want True if the index is just arbitrary row numbers.
to_wgs84: bool, optional, default: False: If the CRS is set on the active geometry column it is exported as WGS84 (EPSG:4326) to meet the 2016 GeoJSON specification. Set to True to force re-projection and set to False to ignore CRS. False by default.
*kwargs* that will be passed to json.dumps().

Returns:

JSON string

Examples

>>> from shapely.geometry import Point
>>> s = geopandas.GeoSeries([Point(1, 1), Point(2, 2), Point(3, 3)])
>>> s
0    POINT (1 1)
1    POINT (2 2)
2    POINT (3 3)
dtype: geometry

>>> s.to_json()
