snowflake.snowpark.functions.st_geomfromgeohash¶

snowflake.snowpark.functions.st_geomfromgeohash(geohash: Union[snowflake.snowpark.column.Column, str], precision: Union[snowflake.snowpark.column.Column, str] = None) → Column[source]¶

Constructs a GEOMETRY object from a geohash string.

Parameters:

geohash (ColumnOrName) – A column or string containing the geohash value
precision (ColumnOrName, optional) – A column or value specifying the precision level for the geohash conversion

Returns:

A GEOMETRY object representing the polygon area covered by the geohash

Return type:

Column
