ST_S2ToGeom

Introduction: Returns an array of Polygons for the corresponding S2 cell IDs.

!!!Hint To convert a Polygon array to MultiPolygon, use ST_Collect. However, the result may be an invalid geometry. Apply ST_MakeValid to the ST_Collect output to ensure a valid MultiPolygon.

An alternative approach to consolidate a Polygon array into a Polygon/MultiPolygon, use the [ST_Union](../Overlay-Functions/ST_Union.md) function.

Format: ST_S2ToGeom(cellIds: Array[Long])

Return type: Array<Geometry>

Since: v1.6.0

SQL Example:

SELECT ST_S2ToGeom(array(11540474045136890))

Output:

[POLYGON ((-36.609392788630245 -38.169532607255846, -36.609392706252954 -38.169532607255846, -36.609392706252954 -38.169532507473015, -36.609392788630245 -38.169532507473015, -36.609392788630245 -38.169532607255846))]
