Returns an array of H3 cell IDs at the specified target resolution that are contained within the input array of H3 cell IDs. This function uncompacts H3 cells to a finer resolution.

Parameters:

  • array_of_cell_ids (ColumnOrName) – An array of H3 cell ID strings.

  • target_resolution (ColumnOrName) – The target H3 resolution (0-15).

Returns:

An array of H3 cell ID strings at the target resolution.

Return type:

Column

Example:

>>> from snowflake.snowpark.functions import array_construct, lit
>>> df = session.create_dataframe([
...     [['8a2a1072339ffff', '892a1072377ffff']],
...     [['8a2a1072339ffff']]
... ], schema=["cell_ids"])
>>> df.select(h3_uncompact_cells_strings(df["cell_ids"], lit(10)).alias("uncompacted")).collect()
[Row(UNCOMPACTED='[\n  "8a2a1072339ffff",\n  "8a2a10723747fff",\n  "8a2a1072374ffff",\n  "8a2a10723757fff",\n  "8a2a1072375ffff",\n  "8a2a10723767fff",\n  "8a2a1072376ffff",\n  "8a2a10723777fff"\n]'), Row(UNCOMPACTED='[\n  "8a2a1072339ffff"\n]')]
