geopandas.GeoSeries.geom_equals_identical

GeoSeries.geom_equals_identical(other, align=None)

Return True for all geometries that are identical aligned other, else False.

This function verifies whether geometries are pointwise equivalent by checking that the structure, ordering, and values of all vertices are identical in all dimensions.

Similarly to geom_equals_exact(), this function uses exact coordinate equality and requires coordinates to be in the same order for all components (vertices, rings, or parts) of a geometry. However, in contrast to geom_equals_exact(), this function does not allow specifying specify a tolerance, and additionally requires all dimensions to be the same (geom_equals_exact() ignores the Z and M dimensions), where NaN values are considered to be equal to other NaN values.

This function is the vectorized equivalent of scalar equality of geometry objects (a == b, i.e. __eq__).

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

Requires Shapely >= 2.1.

Added in version 1.1.0.

Parameters:

otherGeoSeries or geometric object

The GeoSeries (elementwise) or geometric object to compare to.

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 Point
>>> s = geopandas.GeoSeries(
...     [
...         Point(0, 1.1),
...         Point(0, 1.0),
...         Point(0, 1.2),
...     ]
... )
>>> s
0    POINT (0 1.1)
1      POINT (0 1)
2    POINT (0 1.2)
dtype: geometry

>>> s.geom_equals_identical(Point(0, 1))
0    False
1     True
2    False
dtype: bool
