ST_Buffer (Python)

Calculate a geometry that represents all points whose distance from the input geometry column is equal to or less than a given amount. SQL reference: ST_Buffer

Signature

from sedona.spark.sql.st_functions import ST_Buffer

ST_Buffer(
    geometry: ColumnOrName,
    buffer: ColumnOrNameOrNumber,
    useSpheroid: Optional[Union[ColumnOrName, bool]] = False,
    parameters: Optional[Union[ColumnOrName, str]] = None,
) -> Column

Parameters

ColumnOrName

required

Input geometry column to buffer.

ColumnOrNameOrNumber

required

Either a column or value for the amount to buffer the input geometry by.

Optional[Union[ColumnOrName, bool]]

default:"False"

Whether to buffer on the spheroid, with the buffer amount in meters, instead of in the geometry’s planar coordinates. Default is False.

Optional[Union[ColumnOrName, str]]

default:"None"

Buffer style parameters as blank-separated key=value pairs, such as “quad_segs=8 endcap=round”.

Returns

Column

Buffered geometry as a geometry column.
