Parameters:: geography_or_geometry_expression (ColumnOrName) – A GEOGRAPHY or GEOMETRY object.
Returns:: The minimum Y coordinate value.
Return type:: Column

Examples::

>>> from snowflake.snowpark.functions import to_geography
>>> df = session.create_dataframe([
...     ['POINT(-180 0)'],
...     ['POINT(180 0)'],
...     ['LINESTRING(-60 30, 60 30)'],
...     ['LINESTRING(-60 -30, 60 -30)']
... ], schema=["geometry"])
>>> df.select(st_ymin(to_geography(df["geometry"])).alias("ymin")).collect()
[Row(YMIN=0.0), Row(YMIN=0.0), Row(YMIN=29.999999999999943), Row(YMIN=-49.106605350869174)]
