# ST_S2CellIDs

Cover the geometry with Google S2 Cells, return the corresponding cell IDs with the given level.
The level indicates the [size of cells](https://s2geometry.io/resources/s2cell_statistics.html). With a bigger level,
the cells will be smaller, the coverage will be more accurate, but the result size will be exponentially increasing.

## Signatures

```sql theme={"system"}
ST_S2CellIDs(geom: Geometry, level: Integer)
```

## Parameters

<ParamField body="geom" type="Geometry" required>
  The input geometry.
</ParamField>

<ParamField body="level" type="Integer" required>
  The level value.
</ParamField>

## Return type

<ResponseField type="Array<Long>">
  An integer value.
</ResponseField>

## Example

```sql theme={"system"}
SELECT ST_S2CellIDs(ST_GeomFromText('LINESTRING(1 3 4, 5 6 7)'), 6)
```
