GeoSeries.
geom_equals
Returns a Series of dtype('bool') with value True for each aligned geometry equal to other.
Series
dtype('bool')
True
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:
The GeoSeries (elementwise) or geometric object to test for equality.
If True, automatically aligns GeoSeries based on their indices. If False, the order of elements is preserved.

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 ((0.00000 0.00000, 2.00000 2.00000, 0.... 1 POLYGON ((0.00000 0.00000, 1.00000 2.00000, 0.... 2 LINESTRING (0.00000 0.00000, 0.00000 2.00000) 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 POINT (0.00000 1.00000) 4 LINESTRING (0.00000 0.00000, 0.00000 2.00000) 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:
align=True
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
