# GeoSeries.interpolate

> Return a point at the specified distance along each geometry.

Return a point at the specified distance along each geometry.

## Signature

```python theme={"system"}
interpolate(distance, normalized=False) -> GeoSeries
```

## Parameters

<ParamField path="distance" type="float or Series of floats" required>
  Distance(s) along the geometries at which a point should be
  returned. If np.array or pd.Series are used then it must have
  same length as the GeoSeries.
</ParamField>

<ParamField path="normalized" type="bool (default False)" default="False">
  If True, `distance` will be interpreted as a fraction
  of the geometric object's length.
</ParamField>

## Returns

<ResponseField name="return" type="GeoSeries" />

## Examples

```python theme={"system"}
>>> from sedona.spark.geopandas import GeoSeries
>>> from shapely.geometry import LineString
>>> s = GeoSeries(
...     [
...         LineString([(0, 0), (2, 0), (0, 2)]),
...         LineString([(0, 0), (2, 2)]),
...         LineString([(2, 0), (0, 2)]),
...     ],
... )
```

```python theme={"system"}
>>> s.interpolate(1)
0                POINT (1 0)
1    POINT (0.70711 0.70711)
2    POINT (1.29289 0.70711)
dtype: geometry
