geopandas.GeoSeries.interpolate

GeoSeries.interpolate(distance, normalized=False)

Return a point at the specified distance along each geometry

Parameters:

distancefloat or Series of floats

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.

normalizedboolean

If normalized is True, distance will be interpreted as a fraction of the geometric object’s length.

Examples

>>> from shapely.geometry import LineString, Point
>>> s = geopandas.GeoSeries(
...     [
...         LineString([(0, 0), (2, 0), (0, 2)]),
...         LineString([(0, 0), (2, 2)]),
...         LineString([(2, 0), (0, 2)]),
...     ],
... )
>>> s
0    LINESTRING (0 0, 2 0, 0 2)
1         LINESTRING (0 0, 2 2)
2         LINESTRING (2 0, 0 2)
dtype: geometry

>>> s.interpolate(1)
0                POINT (1 0)
1    POINT (0.70711 0.70711)
2    POINT (1.29289 0.70711)
dtype: geometry

>>> s.interpolate([1, 2, 3])
0                POINT (1 0)
1    POINT (1.41421 1.41421)
2                POINT (0 2)
