GeoSeries.contains(other, *args, **kwargs)#

Returns a `Series` of `dtype('bool')` with value `True` for each aligned geometry that contains other.

This docstring was copied from geopandas.base.GeoPandasBase.contains.

Some inconsistencies with the Dask version may exist.

An object is said to contain other if at least one point of other lies in the interior and no points of other lie in the exterior of the object. (Therefore, any given polygon does not contain its own boundary – there is not any point that lies in the interior.) If either object is empty, this operation returns `False`.

This is the inverse of `within()` in the sense that the expression `a.contains(b) == b.within(a)` always evaluates to `True`.

The operation works on a 1-to-1 row-wise manner:

Parameters:
otherGeoSeries or geometric object

The GeoSeries (elementwise) or geometric object to test if it is contained.

alignbool (default True) (Not supported in Dask)

If True, automatically aligns GeoSeries based on their indices. If False, the order of elements is preserved.

Returns:
Series (bool)

Notes

This method works in a row-wise manner. It does not check if an element of one GeoSeries `contains` any element of the other one.

Examples

```>>> from shapely.geometry import Polygon, LineString, Point
>>> s = geopandas.GeoSeries(
...     [
...         Polygon([(0, 0), (1, 1), (0, 1)]),
...         LineString([(0, 0), (0, 2)]),
...         LineString([(0, 0), (0, 1)]),
...         Point(0, 1),
...     ],
...     index=range(0, 4),
... )
>>> s2 = geopandas.GeoSeries(
...     [
...         Polygon([(0, 0), (2, 2), (0, 2)]),
...         Polygon([(0, 0), (1, 2), (0, 2)]),
...         LineString([(0, 0), (0, 2)]),
...         Point(0, 1),
...     ],
...     index=range(1, 5),
... )
```
```>>> s
0    POLYGON ((0.00000 0.00000, 1.00000 1.00000, 0....
1        LINESTRING (0.00000 0.00000, 0.00000 2.00000)
2        LINESTRING (0.00000 0.00000, 0.00000 1.00000)
3                              POINT (0.00000 1.00000)
dtype: geometry
```
```>>> s2
1    POLYGON ((0.00000 0.00000, 2.00000 2.00000, 0....
2    POLYGON ((0.00000 0.00000, 1.00000 2.00000, 0....
3        LINESTRING (0.00000 0.00000, 0.00000 2.00000)
4                              POINT (0.00000 1.00000)
dtype: geometry
```

We can check if each geometry of GeoSeries contains a single geometry:

```>>> point = Point(0, 1)
>>> s.contains(point)
0    False
1     True
2    False
3     True
dtype: bool
```

We can also check two GeoSeries against each other, row by row. The GeoSeries above have different indices. We can either align both GeoSeries based on index values and compare elements with the same index using `align=True` or ignore index and compare elements based on their matching order using `align=False`:

```>>> s2.contains(s, align=True)
0    False
1    False
2    False
3     True
4    False
dtype: bool
```
```>>> s2.contains(s, align=False)
1     True
2    False
3     True
4     True
dtype: bool
```
