GeoSeries.
crosses
Returns a Series of dtype('bool') with value True for each aligned geometry that cross other.
Series
dtype('bool')
True
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:
The GeoSeries (elementwise) or geometric object to test if is crossed.
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 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 ((0.00000 0.00000, 2.00000 2.00000, 0.... 1 LINESTRING (0.00000 0.00000, 2.00000 2.00000) 2 LINESTRING (2.00000 0.00000, 0.00000 2.00000) 3 POINT (0.00000 1.00000) dtype: geometry
>>> s2 1 LINESTRING (1.00000 0.00000, 1.00000 3.00000) 2 LINESTRING (2.00000 0.00000, 0.00000 2.00000) 3 POINT (1.00000 1.00000) 4 POINT (0.00000 1.00000) 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 using align=False:
align=True
align=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.
