# GeoSeries.crosses

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

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

An object is said to cross `other` if its `interior` intersects the
`interior` of the other but does not contain it, and the dimension of
the intersection is less than the dimension of the one or the other.

The underlying Sedona expression returns `NULL` when a
GeometryCollection is involved. This GeoSeries method normalizes that
result to `False` to preserve GeoPandas' non-nullable boolean
contract.

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

## Signature

```python theme={"system"}
crosses(other, align=None) -> pspd.Series
```

## Parameters

<ParamField path="other" type="GeoSeries or geometric object" required>
  The GeoSeries (elementwise) or geometric object to test if is
  crossed.
</ParamField>

<ParamField path="align" type="bool | None (default 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
>>> 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.crosses(line)
0     True
1     True
2     True
3    False
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.crosses(s2, align=True)
0    False
1     True
2    False
3    False
4    False
dtype: bool
```

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

Notice that a line does not cross a point that it contains.
