ST_S2CellIDs

Introduction: Cover the geometry with Google S2 Cells, return the corresponding cell IDs with the given level. The level indicates the size of cells. With a bigger level, the cells will be smaller, the coverage will be more accurate, but the result size will be exponentially increasing.

Format: ST_S2CellIDs(geom: Geometry, level: Integer)

Since: v1.4.0

SQL Example

SELECT ST_S2CellIDs(ST_GeomFromText('LINESTRING(1 3 4, 5 6 7)'), 6)

Output:
