snowflake.snowpark.functions.st_makepolygonoriented

snowflake.snowpark.functions.st_makepolygonoriented(geography_expression: Union[snowflake.snowpark.column.Column, str]) → Column[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.47.0/src/snowflake/snowpark/_functions/scalar_functions.py#L2763-L2797)

Returns a polygon with vertices oriented in a consistent direction (counter-clockwise for exterior rings, clockwise for interior rings).

Parameters:

geography_expression (ColumnOrName) – The geography expression (typically a LINESTRING) to convert to an oriented polygon.

Returns:

The oriented polygon geometry.

Return type:

Column

Examples::
>>> from snowflake.snowpark.functions import col, to_geography
>>> import json
>>> df = session.create_dataframe([

... ], schema=["linestring"])
>>> result = df.select(st_makepolygonoriented(to_geography(col("linestring"))).alias("polygon")).collect()
>>> assert json.loads(result[0]["POLYGON"]) == {
