# GeoSeries.intersects

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

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

An object is said to intersect `other` if its `boundary` and `interior`
intersects in any way with those of the other.

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

## Signature

```python theme={"system"}
intersects(
    other: Union[GeoSeries, BaseGeometry],
    align: Union[bool, None] = None,
) -> pspd.Series
```

## Parameters

<ParamField path="other" type="Union[GeoSeries, BaseGeometry]" required>
  The GeoSeries (elementwise) or geometric object to test if is
  intersected.
</ParamField>

<ParamField path="align" type="Union[bool, None]" default="None">
  If True, automatically aligns GeoSeries based on their indices. None defaults to True.
  If False, the order of elements is preserved.
</ParamField>

## Returns

<ResponseField name="return" type="Series(bool)" />

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

## Examples

```python theme={"system"}
>>> from sedona.spark.geopandas import GeoSeries
>>> from shapely.geometry import Polygon, LineString, Point
>>> s = GeoSeries(
...     [
...         Polygon([(0, 0), (2, 2), (0, 2)]),
...         LineString([(0, 0), (2, 2)]),
...         LineString([(2, 0), (0, 2)]),
...         Point(0, 1),
...     ],
... )
>>> s2 = GeoSeries(
...     [
...         LineString([(1, 0), (1, 3)]),
...         LineString([(2, 0), (0, 2)]),
...         Point(1, 1),
...         Point(0, 1),
...     ],
...     index=range(1, 5),
... )
```

```python theme={"system"}
>>> s
0    POLYGON ((0 0, 2 2, 0 2, 0 0))
1             LINESTRING (0 0, 2 2)
2             LINESTRING (2 0, 0 2)
3                       POINT (0 1)
dtype: geometry
```

```python theme={"system"}
>>> s2
1    LINESTRING (1 0, 1 3)
2    LINESTRING (2 0, 0 2)
3              POINT (1 1)
4              POINT (0 1)
dtype: geometry
```

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

```python theme={"system"}
>>> line = LineString([(-1, 1), (3, 1)])
>>> s.intersects(line)
0    True
1    True
2    True
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`:

```python theme={"system"}
>>> s.intersects(s2, align=True)
0    False
1     True
2     True
3    False
4    False
dtype: bool
```

```python theme={"system"}
>>> s.intersects(s2, align=False)
0    True
1    True
2    True
3    True
dtype: bool
```
