geopandas.GeoSeries.fillna#
- GeoSeries.fillna(value=None, inplace=False, **kwargs)[source]#
Fill NA values with geometry (or geometries).
- Parameters:
- valueshapely geometry or GeoSeries, default None
If None is passed, NA values will be filled with GEOMETRYCOLLECTION EMPTY. If a shapely geometry object is passed, it will be used to fill all missing values. If a
GeoSeries
orGeometryArray
are passed, missing values will be filled based on the corresponding index locations. If pd.NA or np.nan are passed, values will be filled withNone
(not GEOMETRYCOLLECTION EMPTY).
- Returns:
- GeoSeries

Examples
>>> from shapely.geometry import Polygon >>> s = geopandas.GeoSeries( ... [ ... Polygon([(0, 0), (1, 1), (0, 1)]), ... None, ... Polygon([(0, 0), (-1, 1), (0, -1)]), ... ] ... ) >>> s 0 POLYGON ((0 0, 1 1, 0 1, 0 0)) 1 None 2 POLYGON ((0 0, -1 1, 0 -1, 0 0)) dtype: geometry
Filled with an empty polygon.
>>> s.fillna() 0 POLYGON ((0 0, 1 1, 0 1, 0 0)) 1 GEOMETRYCOLLECTION EMPTY 2 POLYGON ((0 0, -1 1, 0 -1, 0 0)) dtype: geometry
Filled with a specific polygon.
>>> s.fillna(Polygon([(0, 1), (2, 1), (1, 2)])) 0 POLYGON ((0 0, 1 1, 0 1, 0 0)) 1 POLYGON ((0 1, 2 1, 1 2, 0 1)) 2 POLYGON ((0 0, -1 1, 0 -1, 0 0)) dtype: geometry
Filled with another GeoSeries.
>>> from shapely.geometry import Point >>> s_fill = geopandas.GeoSeries( ... [ ... Point(0, 0), ... Point(1, 1), ... Point(2, 2), ... ] ... ) >>> s.fillna(s_fill) 0 POLYGON ((0 0, 1 1, 0 1, 0 0)) 1 POINT (1 1) 2 POLYGON ((0 0, -1 1, 0 -1, 0 0)) dtype: geometry
