ST_ConcaveHull(
    geometry: ColumnOrName,
    pctConvex: Union[ColumnOrName, float],
    allowHoles: Optional[Union[ColumnOrName, bool]] = None,
) -> Column

Parameters

ColumnOrName

required

Geometry column to generate a cancave hull for.

Union[ColumnOrName, float]

required

value between 0 and 1, controls the concaveness of the computed hull.

Optional[Union[ColumnOrName, bool]]

default:"None"

The computed hull will not contain holes unless allowHoles is specified as true

Returns

Column
