geopandas.GeoSeries.crosses#
- GeoSeries.crosses(other, align=None)[source]#
Returns a
Series
ofdtype('bool')
with valueTrue
for each aligned geometry that cross other.An object is said to cross other if its interior intersects the interior of the other but does not contain it, and the dimension of the intersection is less than the dimension of the one or 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 if is crossed.
- 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
crosses
any element of the other one.Examples
>>> from shapely.geometry import Polygon, LineString, Point >>> s = geopandas.GeoSeries( ... [ ... Polygon([(0, 0), (2, 2), (0, 2)]), ... LineString([(0, 0), (2, 2)]), ... LineString([(2, 0), (0, 2)]), ... Point(0, 1), ... ], ... ) >>> s2 = geopandas.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.crosses(line) 0 True 1 True 2 True 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 usingalign=False
:>>> s.crosses(s2, align=True) 0 False 1 True 2 False 3 False 4 False dtype: bool
>>> s.crosses(s2, align=False) 0 True 1 True 2 False 3 False dtype: bool
Notice that a line does not cross a point that it contains.
