ST_StraightSkeleton (Python)

Compute the straight skeleton of an areal geometry. The straight skeleton is a method of representing a polygon by a topological skeleton formed by a continuous shrinking process where each edge moves inward in parallel at a uniform speed. SQL reference: ST_StraightSkeleton

Signature

from sedona.spark.sql.st_functions import ST_StraightSkeleton

ST_StraightSkeleton(
    geometry: ColumnOrName,
    max_vertices: Optional[Union[ColumnOrName, int]] = None,
) -> Column

Parameters

ColumnOrName

required

Polygon or MultiPolygon geometry column to compute the straight skeleton for.

Optional[Union[ColumnOrName, int]]

default:"None"

Optional maximum number of vertices to keep in the input geometry before computing. If the geometry has more vertices, it will be simplified. This improves performance for complex geometries.

Returns

Column

MultiLineString representing the straight skeleton as a geometry column.
