dask_geopandas.GeoSeries.is_ring

dask_geopandas.GeoSeries.is_ring#

property GeoSeries.is_ring#

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

This docstring was copied from geopandas.base.GeoPandasBase.is_ring.

Some inconsistencies with the Dask version may exist.

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, ...
