geopandas.GeoSeries.is_ring

property GeoSeries.is_ring

Returns a Series of dtype('bool') with value True for features that are closed.

When constructing a LinearRing, the sequence of coordinates may be explicitly closed by passing identical values in the first and last indices. Otherwise, the sequence will be implicitly closed by copying the first tuple to the last index.

Examples

>>> from shapely.geometry import LineString, LinearRing
>>> s = geopandas.GeoSeries(
...     [
...         LineString([(0, 0), (1, 1), (1, -1)]),
...         LineString([(0, 0), (1, 1), (1, -1), (0, 0)]),
...         LinearRing([(0, 0), (1, 1), (1, -1)]),
...     ]
... )
>>> s
0    LINESTRING (0.00000 0.00000, 1.00000 1.00000, ...
1    LINESTRING (0.00000 0.00000, 1.00000 1.00000, ...
2    LINEARRING (0.00000 0.00000, 1.00000 1.00000, ...
dtype: geometry

>>> s.is_ring
