# GeoDataFrame.is_simple

> Returns a Series of dtype('bool') with value True for geometries that do not cross themselves.

Returns a `Series` of `dtype('bool')` with value `True` for
geometries that do not cross themselves.

This is meaningful only for `LineStrings` and `LinearRings`.

## Examples

```python theme={"system"}
>>> from sedona.spark.geopandas import GeoSeries
>>> from shapely.geometry import LineString
>>> s = GeoSeries(
...     [
...         LineString([(0, 0), (1, 1), (1, -1), (0, 1)]),
...         LineString([(0, 0), (1, 1), (1, -1)]),
...     ]
... )
>>> s
0    LINESTRING (0 0, 1 1, 1 -1, 0 1)
1         LINESTRING (0 0, 1 1, 1 -1)
dtype: geometry
```

```python theme={"system"}
>>> s.is_simple
0    False
1     True
dtype: bool
```

## Signature

```python theme={"system"}
GeoDataFrame.is_simple
```
