snowflake.snowpark.functions.st_azimuth¶

snowflake.snowpark.functions.st_azimuth(geography_or_geometry_origin: Union[snowflake.snowpark.column.Column, str], geography_or_geometry_target: Union[snowflake.snowpark.column.Column, str]) → Column[source]¶

Calculates the azimuth (bearing) in radians from the origin point to the target point. The azimuth is measured clockwise from north and returned as a value between 0 and 2π.

Parameters:

• geography_or_geometry_origin (ColumnOrName) – The origin point as a GEOGRAPHY or GEOMETRY object

• geography_or_geometry_target (ColumnOrName) – The target point as a GEOGRAPHY or GEOMETRY object

Returns:

The azimuth in radians from origin to target point

Return type:

Column
