# GeoDataFrame.difference

> Returns a GeoSeries of the points in each aligned geometry that are not in other.

Returns a `GeoSeries` of the points in each aligned geometry that
are not in `other`.

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

Unlike Geopandas, Sedona does not support this operation for GeometryCollections.

## Signature

```python theme={"system"}
difference(other, align=None)
```

## Parameters

<ParamField path="other" type="Geoseries or geometric object" required>
  The Geoseries (elementwise) or geometric object to find the
  difference to.
</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="GeoSeries" />

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

## 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)]),
...         Polygon([(0, 0), (2, 2), (0, 2)]),
...         LineString([(0, 0), (2, 2)]),
...         LineString([(2, 0), (0, 2)]),
...         Point(0, 1),
...     ],
... )
>>> s2 = GeoSeries(
...     [
...         Polygon([(0, 0), (1, 1), (0, 1)]),
...         LineString([(1, 0), (1, 3)]),
...         LineString([(2, 0), (0, 2)]),
...         Point(1, 1),
...         Point(0, 1),
...     ],
...     index=range(1, 6),
... )
```

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

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

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

```python theme={"system"}
>>> point = Point(0, 1)
>>> s2.difference(point)
1    POLYGON ((0 0, 1 1, 0 1, 0 0))
2             LINESTRING (1 0, 1 3)
3             LINESTRING (2 0, 0 2)
4                       POINT (1 1)
5           GEOMETRYCOLLECTION EMPTY
dtype: geometry
```

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.difference(s2, align=True)
0    POLYGON ((0 0, 2 2, 0 2, 0 0))
1    POLYGON ((0 0, 2 2, 0 2, 0 0))
2             LINESTRING (0 0, 2 2)
3             LINESTRING (2 0, 0 2)
4                       POINT (0 1)
5                       POINT (0 1)
dtype: geometry
```

```python theme={"system"}
>>> s.difference(s2, align=False)
0    POLYGON ((0 0, 2 2, 0 2, 0 0))
1    POLYGON ((0 0, 2 2, 0 2, 0 0))
2           GEOMETRYCOLLECTION EMPTY
3             LINESTRING (2 0, 0 2)
4           GEOMETRYCOLLECTION EMPTY
dtype: geometry
```
