GeoDataFrame.intersects

Returns a Series of dtype('bool') with value True for each aligned geometry that intersects other. An object is said to intersect other if its boundary and interior intersects in any way with those of the other. The operation works on a 1-to-1 row-wise manner.

Signature

intersects(other, align=None)

Parameters

GeoSeries or geometric object

required

The GeoSeries (elementwise) or geometric object to test if is intersected.

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.

Returns

Series(bool)

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

>>> 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),
... )

>>> 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:

>>> line = LineString([(-1, 1), (3, 1)])
>>> s.intersects(line)
0    True
1    True
2    True
3    True
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.intersects(s2, align=True)
  False
   True
   True
  False
  False
dtype: bool

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