# geopandas.GeoSeries.geom_equals#

GeoSeries.geom_equals(other, align=None)[source]#

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

An object is said to be equal to other if its set-theoretic boundary, interior, and exterior coincides with those of the other.

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

Parameters:
otherGeoSeries or geometric object

The GeoSeries (elementwise) or geometric object to test for equality.

alignbool | None (default None)

If True, automatically aligns GeoSeries based on their indices. If False, the order of elements is preserved. None defaults to True.

Returns:
Series (bool)

Notes

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

Examples

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

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

```>>> polygon = Polygon([(0, 0), (2, 2), (0, 2)])
>>> s.geom_equals(polygon)
0     True
1    False
2    False
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`:

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